The objective of this work is to develop a near-infrared laser device capable of emitting orbital angular momentum (OAM) light. The prototyped device must be suitable for compact, energy-saving optical communication applications. Integrated OAM lasers will revolutionize high-capacity data transmission over any telecommuni- cation network environment, as OAM light can be guided and transmitted through kilometers of optical fibers and propagated in free space and underwater. Several methods for generating OAM light employing various complex monolithic and hybrid integration methods have been demonstrated. In this work, microscale integrated spiral phase plates (SPPs) are chosen to convert the laser beam output into an OAM mode. The concept and design fundamentals of SPPs are discussed, followed by the SPP fabrication process and their implementation in a high-speed communication setup and then integration with a semiconductor laser. SPPs are fabricated by a novel direct laser writing that provides the possibility to rapidly prototype 3D photonic structures via a two-photon polymerization pro- cess. After fabrication, SPPs are used in a fine-tuned free-space optical experimental setup that requires high-precision intercomponent alignment to test the high-speed OAM communication system and analyze the quality of OAM modes, resulting in high-purity OAM signals at data rates up to 1.8 Gbit/s – limited by the avalanche photodetector (APD) frequency response. The fabricated 20-μm-diameter SPPs were the smallest reported in the literature to date for optical characterization. A proof-of-concept monolithic light-emitting array, as a highly integrated OAM laser source, is further proposed for telecommunications and other applications. SPP-integrated 940-nm vertical-cavity surface-emitting laser (VCSEL) array chips that are relatively low-cost, have a small footprint, and are manufacturable in high volumes are developed. SPPs with topological charge modulus values from 1 to 3 are fabricated on the VCSEL arrays, demonstrating OAM modal purities up to ∼65%. The experimentally evaluated data rates in the OAM setup showed consistently sta- ble links up to 2.0 Gbit/s with a bit error ratio of ∼ 1.6 × 10−8 (APD-limited). The challenges of SPP-laser integration are summarized, with the conclusion that the widespread adoption of OAM is limited by the availability of practical integrated solutions for OAM generation and detection.

Self-heating leads to temperature rise of laser diode and limits the output power, efficiency and modulation bandwidth due to increased loss and decreased differential gain. The main heat sources in laser diode during continuous wave operation are Joule heating and free carrier absorption loss. To control device self-heating, the epi structure needs to be designed with low electrical resistance and low absorption loss, while the heat flux must spread out of the device efficiently. This dissertation presents the control of self-heating of both edge emitting laser diodes and vertical cavity surface emitting lasers (VCSELs). For the 980nm high power edge emitting laser, asymmetric waveguide is used for low free carrier absorption loss. The waveguide and cladding materials are optimized for high injection efficiency. BeO heatsink is applied to spread the heat efficiently. Injection efficiency of 71% and internal loss of 0.3 cm-1 have been achieved. A total output power of 9.3 W is measured from 0.5cm long device at 14.5A injection current. To further reduce the internal loss, the development of 980nm quantum dot active region is studied. Threshold current density as low as 59A/cm2 is reached. For the VCSELs, oxide-free structure is used to solve the self-heating problem of oxide VCSELs. Removing the oxide layer and using AlAs in the DBRs leads to record low thermal resistance. Optimization of the DBRs leads to low resistance and low free carrier absorption. Power conversion efficiency higher than 50% is achieved. To further reduce device voltage and heat generation, the development of intracavity contacts devices is introduced.

Frequency domain functional near infrared spectroscopy (FD-fNIRS) is a tissue optical measurement technique used to measure absolute haemoglobin concentrations in brain tissue. This work is intended to be the first step in the development of a wearable, low-cost FD-fNIRS device for neurofeedback applications. The system requirements were generated from a review of relevant literature. A simplified system architecturewas developed based on the various instrumentation methodologies proposed by various authors. The functional blocks of this system were prototyped and their performance was evaluated. The developed vertical-cavity surface-emitting laser (VCSEL) current source was found to have a span of 10uA which meets the design specifications. Challenges exist in optimally biasing silicon photomultiplier (SiPM), which is susceptible to optical and electronic noise sources.

Ce travail de thèse porte sur l'étude et le développement de composants à cavité verticale dans le contexte des réseaux courtes et moyennes distances multiplexés en longueur d'onde autour de 1,55 μm. Pour fabriquer de telles structures, nous avons tout d'abord développé des miroirs de Bragg diélectriques constitués de silicium amorphe et de nitrure de silicium. La différence d'indice (1,9) élevée entre ces matériaux a permis d'atteindre les hautes réflectivités (R = 99,5%) nécessaires au bon fonctionnement des VCSELs. A la suite du développement de ces miroirs, nous avons réalisé un VCSEL, reporté sur substrat silicium par collage métallique AuIn2, comprenant deux miroirs diélectriques et une zone active à base de puits quantiques InGaAs/InGaAsP. Les caractérisations et les études par simulation du VCSEL ont engendré plusieurs optimisations, et ont permis d'obtenir une émission laser continue sous pompage optique jusqu'à une température de 35°C. Ces résultats encourageants ont validé notre processus de fabrication ainsi que la fiabilité et la bonne qualité des miroirs de Bragg diélectriques. Pour s'affranchir du caractère instable de la polarisation de ces VCSELs nous avons proposé l'utilisation de nanostructures quantiques InAs/InP anisotropes se présentant sous forme de fils. L'étude de ces structures et leur mise en cavité ont démontré leur intérêt pour introduire une anisotropie du gain permettant d'assurer une polarisation stable. Nous avons développé un VCSEL accordable suivant une nouvelle approche. Le principe repose sur l'insertion d'une couche de phase électro-optique à base de nano-PDLC (Polymer Dispersed Liquid Crystal) dans la cavité du VCSEL. Le nano-PDLC, permet d'obtenir une variation isotrope de l'indice de réfraction sous l'action d'une tension. La réalisation d'un prototype pompé optiquement a permis une première démonstration de faisabilité d'un VCSEL accordable par voie électro-optique. Une accordabilité de 10-nm autour de 1.55-μm a été mesurée pour une tension de 170V, et le temps moyen de commutation sur la gamme spectrale est de 30 μs.

L’objectif de cette thèse est de développer un nouveau matériau photopolymère pouvant être microstructuré dans la gamme de longueur d'onde du proche infrarouge (NIR). Le but final de ce travail est de proposer des solutions innovantes pour l'intégration de micro-optique sur les VCSELs (Vertical-Cavity Surface-Emitting Laser), sources lumineuses miniaturisées utilisées dans de nombreuses applications en optique, photonique, capteurs ou biologie. Le verrou technologique principal a consisté à développer et étudier le photopolymère adéquat pour la microfabrication déclenchée par le VCSEL. La difficulté principale tient à la longueur d'onde de photopolymérisation qui est fixé par le VCSEL et qui a obligé à développer un système moléculaire nouveau pour une polymérisation radicalaire à 780 et 850 nm. Une part importante du travail a consisté à étudier les mécanismes photophysiques et photochimiques des matériaux permettant de proposer des systèmes efficaces, sur le plan de la photophysique, de la photochimie de photopolymérisation et également une approche originale a été développée pour appréhender de façon quantitative les phénomènes de diffusion du colorant dans la matrice polymère. Sur la base des systèmes moléculaires proposés, la démonstration de l'intégration de microlentilles sur VCSEL par ce procédé innovant a pu être démontré. Les VCSELs lentillés ont été caractérisés et des propriétés très intéressantes pour la focalisation ont été démontrées. / The objective of this thesis is to develop a new photopolymer material that can be microstructured in the wavelength range of near-infrared (NIR). The ultimate aim of this work is to propose innovative solutions for micro-optical integration on VCSELs (Vertical-Cavity Surface-Emitting Laser). These miniaturized light sources are used in many applications in optics, photonics, sensors or biology. The main technological challenge was to develop and explore a new photopolymer compatible with a microfabrication initiated by the VCSEL. The main difficulty was to develop a new molecular system for radical polymerization at 780 and 850 nm, which is the wavelength emitted by the VCSEL. An important part of the work consisted to study the photophysical and photochemical mechanisms of this photopolymer in order to provide efficient systems in terms of photophysics, photochemistry of the photopolymerization. An original approach was developed to quantitatively apprehend the phenomena dye diffusion in the polymer matrix. Based on the proposed molecular systems, demonstrating the integration of microlenses on VCSELs by this innovative process could be shown. The lensed VCSELs have been characterized and very interesting properties for focusing have been demonstrated.

The vertical-cavity surface-emitting laser or VCSEL is a special type of diode laser, which has established itself in optoelectronic applications asa low-cost, high-quality miniaturized light source. The development of VCSELs can be largely promoted with support from computer simulations. In this study, we have used such simulations, on one hand to understand and improve the VCSEL performance, and on the other hand to prepare for analyzing new device concepts such as transistor-VCSELs. This thesis starts with a background introduction to the principle idea of VCSELs and then states the significance of this simulation work.Then it briefly introduces the previously used simulation workbench Sentaurus and explains the mathematical approach and the computation methods of the finally chosen simulator PICS3D. The case study of a fabricated and characterized epitaxially regrown VCSEL is the major component of this work. First the device configuration is demonstrated with detailed discussion on several design features. Second the physical models of electrical, optical and thermal phenomena along with their key parameters are presented and so are the advanced models for the active region. The main results of simulation, including steady-state characteristics and small-signal modulation, show good agreement with the experimental results and reveal some imperfections of the device design and processing, such as the overestimated stability of the regrown junction and the variation of cavity length caused by over-etch. This work is also treated as an evaluation of the simulator PICS3D, and two problems are identified: one is the troublesome way to construct a 3D device by coupling several 2D layer structures together, requiring the mesh for each layer structure to be compatible; the other would be the tricky boundary setting for the adopted method, Effective Index Method (EIM), for the transverse field calculation when only a weak index guiding effect exits in the cavity. Finally, we summarize this work and suggest some tasks for further simulations.

The aim of this project was to produce an integrate-able free space optical transceiver for Specks. Specks are tiny computing units that together can form a powerful network called a SpeckNet. The SpeckNet platform is developed by the SpeckNet consortium, which consists of five Scottish Universities and combines computer science, electrical engineering and digital signal processing groups. The principal goal of creating an optical transceiver was achieved by integrating in-house fabricated VCSELs (with lasing thresholds below 400 uA) and custom designed detectors on the SpeckNet platform. The transceiver has a very low power consumption (approximately 100 uW), which removes the need for synchronous communication through the SpeckNet thus making the network more efficient. I describe both static and dynamic beam control techniques. For static control, I used micro-lenses. I fabricated the lenses by greyscale electron beam lithography and integrated them directly on VCSEL arrays. I achieved a steering angle of 10 degrees with this design. I also looked at integrated gratings etched straight into a VCSEL and observed beam steering with an efficiency of 60% For dynamic control, I implemented a liquid crystal (LC) design. I built a LC cell with 30 individually controlled pixels, but I only achieved a steering angle of 1 degree. Furthermore, I investigated two different techniques for achieving beam steering by interference, using coupled VCSELs (a phased array approach). Firstly, using photonic crystals etched into the surface of the VCSEL, I built coupled laser cavities. Secondly, I designed and built bow-tie type VCSELs that were optically coupled but electrically isolated. These designs work by differential current injection causing an interference effect in the VCSELs far field. This technique is the first stepping stone towards realising a phased optical array. Finally, I considered signal detection. Using the same VCSEL material, I built a resonant-cavity detector. This detector had a better background rejection ratio than commercially available silicon devices.

This thesis deals with the use of microcavity resonators for the control of light in organic active materials. In addition to the vertical confinement provided by highly reflecting mirrors in a vertical cavity surface emitting laser (VCSEL), in-plane patterning facilitates additional ways to manipulate the cavity dispersion and enables the observation of novel photonic modes in highly confined systems and an improved performance of organic solid state lasers. Furthermore, organic microcavities are employed for efficient spectrally sensitive photodetection in the near infrared. In microcavities comprising two dielectric distributed Bragg reflectors sandwiching an organic active blend of the matrix molecule Alq3 and the laser dye DCM, optically pumped lasing is investigated, exhibiting a broad spectral tunability over 90 nm due to the large gain bandwith of the laser dye. To directly influence the microcavity dispersion, different interlayers are introduced into the system, facilitating a red-shift of the cavity resonance due to the formation of Tamm-plasmon-polariton states (when using plasmonic Ag interlayers) or an increase of the optical cavity thickness (when using non-absorbing layers such as SiO2). Both concepts are explored and enable strong spectral shifts on the order of 10 meV-100 meV when using interlayers of only few tens of nm in thickness. In order to enhance the optical quality of metal-organic microcavities, the growth of noble metal layers on top of organic films can be improved by the use of diffusion barriers, stopping the diffusion of metal atoms into the organics, and seed layers which provide an improved surface wetting. Both concepts in total lead to an enhancement of the quality factor of such devices by a factor of two. The manipulation of the cavity resonance using different interlayers provides the ability to structure the photon energy landscape in the device plane on the microscale. Using photolithography, photonic wires and dots are fabricated to laterally restrict the photons in potential wells, leading to the observation of discretised energy spectra in two and three dimensions. To facilitate an in-depth investigation, dispersion tomography is utilised and yields the angle resolved emission of multi-dimensionally confined photons in all directions. In metal-organic photonic dots and triangular wedges, such three-dimensional trapping is exploited to reduce parasitic modes, leading to reduced thresholds of an organic microlaser by one order of magnitude. Complex transversal modes are observed in the device emission as a result of the strong lateral confinement that is achieved by such patterning. The manipulation of the photon energy landscape can not only be utilised for enhanced confinement but also for the introduction of photonic lattices. By adding periodic stripes of either Ag or SiO2 into an organic microcavity, an optical Kronig-Penney potential is realised, directly showing the formation of photonic Bloch states in the microcavity dispersion. Utilising a modified Kronig-Penney theory, photons are assigned a polarisation-dependent effective mass, facilitating a quantitative allocation of calculated and observed modes and explaining the emergence of zero and pi-phase coupling of spatially extended supermodes. Finally, by utilising an two-beam excitation geometry, direct control over lasing from multiple discretised states can be exerted, enabling spectral and angular tunability of devices on the microscale. In an alternative concept, a full microcavity stack is deposited onto a periodic grating which couples the waveguided (WG) modes in the active cavity layer to the vertical emission. Coherent interaction between linear WG and parabolic vertical modes is indicated by anti-crossing points where the dispersion of both overlaps. In this hybrid system, novel lasing modes arise not only at the position of the VCSEL parabola apex but also at points of hybridization, showing a drastically enhanced in-plane spatial coherence of at least 50 micrometer. Finally, the concept of organic microcavities is applied towards efficient and spectrally sensitive photodetectors. Making use of the intermolecular charge transfer (CT) state in donor-acceptor blends of organic solar cells, the strong field enhancement of a microcavity is exploited to significantly increase the external quantum efficiency of the initially weak CT absorption at resonance. Consequently, near-infrared photodetection is enabled by cavity-enhanced CT state absorption, leading to devices showing competitive specific detectivities without the need of an external voltage and an EQE above 20% (18% at 950 nm) with a full width at half maximum of significantly below 50 nm. The detectors are shown to be tunable in a broad spectral range via the angular dispersion of the optical microcavity or a thickness variation of the electron and hole transport layers in the solar cell. These findings not only facilitate interesting applications but also enable the direct excitation and observation of the CT state that is integral to the working principles of organic solar cells. / Die vorliegende Dissertation beschäftigt sich mit der Kontrolle über Emission und Absorption organischer aktiver Materialien mittels Mikrokavitätsresonatoren. Zusätzlich zum vertikalen Einschluss der Photonen zwischen hochreflektierenden Spiegeln in oberflächenemittierenden Mikrokavitäten (VCSEL, s.o.) werden Strukturierungen in der Bauteilebene hinzugefügt, um eine direkte Manipulation der Photonendispersion zu ermöglichen. Resultierend aus diesen Ergebnissen sind die Beobachtung neuartiger photonischer Moden sowie verbesserte Betriebseigenschaften von organischen Festkörperlasern. Desweiteren wird das Konzept der organischen Mikrokavität zur effizienten und spektral sensitiven Detektion von Nahinfrarot-Photonen angewendet. In Mikrokavitäten aus zwei dielektrischen Bragg-Spiegeln (DBR), welche eine organische aktive Schicht aus dem Matrixmaterial Alq3 und dem Laserfarbstoff DCM einschliessen, wird optisch gepumptes Lasing beobachtet. Dabei ist die Emission spektral über einen weiten Bereich von 90 nm stufenlos einstellbar, was durch die hohe optische Gewinnbandbreite des Laserfarbstoffs ermöglicht wird. Um die Dispersion von Photonen in Mikrokavitäten direkt beeinflussen zu können, werden verschiedene Zwischenschichten in den Laser eingebracht, welche eine Rotverschiebung der Emission nach sich ziehen. In metall-organischen Kavitäten kann dieser Effekt durch die Bildung von Tamm-Plasmon-Polariton Quasiteilchen erklärt werden, die durch die Interaktion der optischen Moden mit den Plasmonen in einer dünnen Silberschicht entstehen. Alternativ werden nichtabsorbierende SiO2-Zwischenschichten eingefügt, welche die optische Kavitätsdicke vergrössern und ähnliche starke Rotverschiebungen der Emission von 10 meV-100 meV nach sich ziehen. Um die optische Qualität metall-organischer Kavitäten zu verbessern, wird das Wachstum der edlen Ag-Schicht auf amorphen organischen Schichten mithilfe von Diffusionsbarrieren und Keimschichten kontrolliert. Die Kombination beider Konzepte ermöglicht eine Verbesserung des Qualitätsfaktors solcher Bauteile um den Faktor 2. Durch die Manipulation der Photonendispersion mithilfe dielektrischer und plasmonischer Zwischenschichten wird eine Strukturierung der photonischen Potentiallandschaft in der Bauteilebene auf Mikrometer-Skala ermöglicht. Mittels Photolithographie werden Photonische Drähte und Punkte hergestellt, welche das Licht auch lateral in Potentialtöpfen einschliessen und zur Beobachtung von diskretisierten Emissionspektren in zwei und drei Dimensionen führen. Um diese Untersuchungen zu erweitern, wird eine tomographische Methode entwickelt, um die winkelaufgelöste Dispersion dieser mehrdimensional eingeschlossenen Photonen in allen Richtungen aufzunehmen. Die Ergebnisse dieser Untersuchung werden in metall-organischen photonischen Punkten und Dreieck-Strukturen ausgenutzt und führen dabei zu einer Verringerung der Laserschwelle von bis zu einer Grössenordnung. Die dabei entstehenden komplexen Transversalmoden sind ein Zeichen für die starke Konzentration des Lichts in solchen Strukturen. Die laterale Strukturierung organischer Mikrokavitäten kann nicht nur für den vollständigen Einschluss von Licht ausgenutzt werden, sondern ermöglicht weiterhin die Beobachtung von photonischen Bandstrukturen in periodischen Gittern. Solch periodische Strukturen bestehend entweder aus Silber oder SiO2 ermöglichen die Realisierung eines optischen Kronig-Penney Potentials in Mikrokavitäten was schlussendlich zur Beobachtung optischer Bloch-Zustände in der Dispersion führt. Durch eine Modifizierung der Kronig-Penney Theorie, bei der unter anderem den Photonen eine polarisationsabhängige effektive Masse zugewiesen wird, ist eine quantitative Berechnung der Modenpositionen in solchen Systemen möglich. In Theorie und experimentellen Untersuchungen wird dabei das Auftreten von 0- oder pi-phasengekoppelten räumlich ausgedehnten Supermoden erklärt. Mithilfe der Anregung durch zwei interferierende Laserstrahlen kann desweiteren eine direkte Kontrolle über die Wellenlänge sowie den Auskopplungswinkel der stimulierten Emission ausgeübt werden. In einem alternativen Konzept der lateralen Strukturierung werden organische Mikrokavitäten auf periodische Gitter aufgedampft, was zu einer kohärenten Kopplung von Wellenleitermoden der aktiven Schicht in die vertikale Emission führt. Diese Moden treten als lineare Dispersion in winkelaufgelösten Spektren auf und zeigen eine direkte Interaktion mit der parabolischen Dispersion der VCSEL-Mode an (Anti-)Kreuzungspunkten. In diesem hybriden System lassen sich neuartige Lasermoden beobachten, welche nicht nur am Scheitelpunkt der Kavitätsparabel auftreten, sondern auch an Punkten, die durch die Hybridisierung beider Systeme entstehen. Diese Kopplung von vertikalen und lateralen Lasermoden zeigt eine drastisch erhöhte Kohärenzlänge von mindestens 50 Mikrometern in der Probenebene. Schließlich wird das Konzept einer organischen Mikrokavität noch in absorbierenden Systemen eingesetzt. Durch das Einbringen einer organischen Solarzelle in eine optische Kavität wird eine starke Erhöhung des Felds im spektralen Bereich des sonst nur schwach absorbierenden intermolekularen Ladungstransferzustands in Donator-Akzeptor Mischschichten ermöglicht. Die Ausnutzung dieses Zustands ermöglicht eine spektral scharfe (Halbwertsbreite deutlich unter 50 nm) Detektion von Nahinfrarotphotonen mit einer externen Quanteneffizienz von über 20% (18% für 950 nm) und einer konkurrenzfähigen spezifischen Detektivität. In weiteren Untersuchungen zeigen sich diese Detektoren als spektral durchstimmbar, zum Einen durch die parabolische Dispersion der Mikrokavität, zum Anderen durch die Variation der Dicken der Elektron- und Lochtransportschichten. Diese Ergebnisse ermöglichen nicht nur interessante Anwendungen, sondern auch die direkte Beobachtung und Anregung des Ladungstransferzustandes, welcher eine zentrale Rolle in der Funktion organischer Solarzellen spielt.

Cette thèse s'inscrit dans le cadre du projet français FUI8-ORIGIN qui vise à développer les performances des réseaux domestiques en apportant des solutions sans multi-Gigabits faiblement radiatives, économes et pérennes. La solution ORIGIN est caractérisée par l'action complémentaire de deux technologies: les communications sans fil 60 GHz, avec notamment la création récente en Janvier 2013 de la nouvelle norme WiFi 60GHz, et la mise en place d'une infrastructure Radio-sur-Fibre (RoF) afin d'étendre la propagation de ses signaux radio fortement atténués par l'atmosphère et les murs, au sein de l'ensemble de la maison. Cette thèse porte sur le développement des composants et modules optoélectroniques bas couts, permettant d'assurer ces contraintes. Le travail implique de couvrir de la puce semi-conducteur au modules et jusqu'au système intégré dans le démonstrateur. Les puces sélectionnées sont caractérisées de manière précise en développant des bancs de mesures adaptées aux applications analogiques RoF. Les performances RoF ont été évaluées et comparées en termes de réponse en fréquence, de bruit et de non-linéarités. Un dimensionnement complet de l'infrastructure Radio-sur-Fibre pour le démonstrateur est ensuite mené, intégrant et dimensionnant le bilan de liaison global à partir modules et cartes réalisés et développés par les partenaires du projet. Le module transmetteur Radio-sur-Fibre (TRoF) est ainsi conçu, assemblé et testé. Les performances du module ont été mesurées et simulées à chaque étape de la procédure d'intégration. Le démonstrateur final basé sur l'architecture multipoint-à-multipoint a été réalisée à l'aide d'un nœud central optoélectronique pour la répartition du signal et d'une Green Box permettant le contrôle de l'allumage des différentes pièces, et ainsi la rationalisation du rayonnement et de la consommation du système. Une transmission bidirectionnelle en temps réel entre deux dispositifs de Wireless HD commerciaux à ~3 Gbit/s a été démontrée. Dans une dernière section de cette thèse, des directions pour améliorer les lasers à cavité émettant par la surface (VCSEL) et les phototransistors SiGe sont explorées. Des VCSEL analogiques avec une bande passante de plus de 25 GHz sont développés avec la société Philips ULM Photonics et mesurés. Notre action s'est concentrée sur les dimensions latérales de la structure, en bénéficiant des améliorations des couches verticale de la part de ULM Photonics. Outre les dimensions du VCSEL propre, ce travail a aussi visé l'amélioration des lignes d'accès pour permettre à la fois une meilleure dissipation thermique et une meilleure adaptation réactive du VCSEL à son électronique amont. Une nouvelle technologie de couplage optique collective et passive est enfin proposée. Originale et brevetée à l'occasion de ce travail, elle permet le couplage optique vertical à la fibre optique multimode et monomode de dispositifs optoélectroniques de petites tailles, inférieurs à 10µm, ainsi permettant simultanément de réduire les pertes de couplage, d'augmenter la fréquence de fonctionnement des composants couplés en réduisant leur dimensions, et de réduire le coût et le temps de réalisation du couplage / Wireless communication technologies have become one of the most popular and indispensable part of people's lives in the recent years, offering mobility and services never before available from mobile communication until local network communication. This work is based on the frame of the French ORIGIN project and intended to explore the Home Area Network using the most recent Wi-Fi standard at 60 GHz with the goal to present a solution for the upcoming days where MultiGbit/s wireless communication will be required. The ORIGIN solution is characterized by the complementary action of two technologies: 60 GHz Wireless communication and Radio-over-Fiber (RoF) infrastructure. The project pretends to propose a real prototype based on RoF transducers and a Multipoint-to-Multipoint architecture to cover the entire house. This thesis covers from the single optoelectronic chip devices until the system implementation and the final demonstrator. The light source and the photodetector choice were very important since it dictated the RoF transducer architecture. Our choice was on 850 nm multimode devices (GaAs VCSEL and SiGe HPT) which allow relaxed constraints on the optical packaging and, therefore, low cost solutions. In terms of performances those devices are limited in a few tens of Gigahertz of bandwidth which was the reason for the intermediate frequency (IF) architecture. This thesis work addressed the electrical and optical interconnection of the optoelectronic chip devices. It explored the integration of hybrid amplification stages and passive networks within optoelectronic receivers and emitters. The optical packaging issues were addressed through a conventional coupling technique using a ball lens first. The die device performances were evaluated and compared with a packaged module in terms of frequency response, noise and nonlinearities. Since performances are usually measured as link performances we proposed a definition of the Opto-microwave figures of merit, such as Opto-microwave gain, noise, nonlinearities and EVM. They are presented and integrated into behavioral models, allowing both the individual performances extraction and system design. The integration of the RoF module in the system is the final part of this thesis. The performances were measured and simulated at each integration step. The final demonstrator based on the multipoint-to-multipoint architecture was implemented using an optoelectronic central node for the signal repartition and the Green Box for signal controlling. Real-time bidirectional transmission between two commercial WirelessHD devices at ~3 Gbit/s was validated. In a final section directions to improve VCSEL and SiGe HPT are explored. 25 GHz analogue VCSELs are explored with a focus on their dimensions, improved access and the potential of a suited matching approach. A novel collective and passive optical coupling technology is also proposed for both VCSEL and top illuminated detectors that couple smaller and faster devices
