As a type of nonlinear system with complexity, mode-locked fiber lasers are known for their complex behaviour. It is a challenging task to understand the fundamental physics behind such complex behaviour, and a unified description for the nonlinear behaviour and the systematic and quantitative analysis of the underlying mechanisms of these lasers have not been developed. Here, we present a complexity science-based theoretical framework for understanding the behaviour of mode-locked fiber lasers by going beyond reductionism. This hierarchically structured framework provides a model with variable dimensionality, resulting in a simple view that can be used to systematically describe complex states. Moreover, research into the attractors' basins reveals the origin of stochasticity, hysteresis and multistability in these systems and presents a new method for quantitative analysis of these nonlinear phenomena. These findings pave the way for dynamics analysis and system designs of mode-locked fiber lasers. We expect that this paradigm will also enable potential applications in diverse research fields related to complex nonlinear phenomena.

Electronic equalization has recently attracted considerable interest for impairment compensation for its significant cost saving and adaptive compensation capability. In this thesis, we propose novel maximum-likelihood sequence estimation (MLSE) structures for various advanced modulation formats. Electronic equalization of advanced modulation formats further extends the transmission reach and relaxes the speed limitation of electronic devices. We also propose novel application of MLSE for mitigation of timing misalignment between the pulse carver and data modulator in return-to-zero (RZ) systems. / In access networks, we focus on the achievement of centralized light source (CLS) wavelength-division-multiplexing passive optical networks (WDM-PON) with data rate of 10 Gbit/s for both downstream and upstream signals. The previous CLS WDM-PON schemes at 10 Gbit/s suffer from chromatic dispersion (CD) and/or asynchronous upstream modulation. We propose two solutions to mitigate these impairments. By eliminating the modulation synchronization module and all-optical CD compensation module, the proposed methods greatly reduce the cost and operation complexity of high-speed WDM-PON. / In the monitoring for impairment compensation, we propose a polarization-insensitive monitoring scheme for synchronized phase re-modulation by using a narrowband optical-passband filter (OBPF). With the optimal central wavelength of the OBPF, high monitoring sensitivity is achieved. / The increasing bandwidth demands have aroused a myriad of industry and academic activities to develop cost-effective optical communication systems with data rates of 10 Gbit/s and beyond. However, as the capacity grows, many signal degradation effects become prominent and seriously limit the data rate and the transmission distance. The mitigation of the impairments inevitably increases the operation complexity and implementation cost. The focus of this thesis is to develop new impairment mitigation approaches to improve the impairment compensation performance and/or to reduce the operation complexity and cost. As a result, cost-effective high-speed optical communication systems are enabled. / To freely enable the employment of advanced modulation formats for optical communications, we propose all-optical conversion from 40-Gbit/s RZ signal to 40-Gbit/s inverse-RZ/10-Gbit/s differential-phase-shift-keying orthogonal modulation signal to interface high-speed transmission systems using RZ format with networks using orthogonal modulation format. We also propose a novel all-optical coding and decoding scheme for 20-Gbit/s four-amplitude-shift-keying signal. / Zhao Jian. / "July 2007." / Adviser: Lian-kuan Chen. / Source: Dissertation Abstracts International, Volume: 69-01, Section: B, page: 0579. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2007. / Includes bibliographical references (p. 152-173). / Electronic reproduction.

Optical time-division-multiplexing is another promising solution for high-speed signal generation. Using the in-fiber PCF-MZI, we have also performed OTDM signal generation at different bit rates. The setup offers comparable performance to commercial multiplexers. We generated 160-Gb/s and 320-Gb/s OTDM signals based on PCF-MZIs. / Orthogonol frequency division multiplexing (OFDM) has attracted quite a lot of interests due to its incomparable advantages in high spectral efficiency optical communication, which significantly enlarges the optical transmission capacity. Optical demultiplexing (DEMUX) of OFDM signals requires FFT processing, which can be efficiently achieved by using cascaded delay interferometers. We theoretically and experimentally studied the transmission properties of cascaded and multi-section Sagnac interferometers and demonstrated their application for the optical OFDM DEMUX. 4-channel OFDM DEMUX is experimentally demonstrated with open eye obtained. / Our study on optical processing of high speed OTDM signals continues with fiber-based techniques using third order nonlinear effects. Based on HNLF, we can construct active fiber interferometer, namely here as nonlinear optical loop mirrors (NOLM). We investigate dispersion asymmetric nonlinear optical loop mirror (DA-NOLM) based on cross phase modulation for simultaneous two-channel demultiplexing (DEMUX) usmg only a single baseband control pulse. Reconfigurable DEMUX has been achieved for 40-Gb/s OTDM signals. The DEMUX are also switchable between two-channel and single-channel operations. Utilizing the tunable delay, DA-NOLM has also been applied to signal processing including pulse format conversions, and repetition rate multiplication. / Photonic crystal fiber based Mach-Zehnder interferometer (PCF-MZI) is constructed by a single line PCF, which is an in-line, all-fiber and coupler free device. As a delay interferometer (DI), PCF-MZI offers enhanced thermal stability in its operation. To date, applications of the in-fiber PCF-MZI are mainly focused on optical sensing instead of communications, which is a major objective in this thesis work. We have fabricated PCF-MZIs with different PCF lengths to introduce desirable delays for optical signal processmg, including differential phase shift keying (DPSK) demodulation, pulse format conversion, repetition rate multiplication and high speed optical time-division-multiplexing (OTDM) signal generation. / The continuously growing Internet traffic has resulted in a huge amount of data flow in the optical networks, particularly along with the recent developments of 3G/4G service, cloud computing, and Internet of things. High-data-rate optical transmission and interconnection are highly desirable in the near future, for next generation communication networks. Accompanied with the traffic growth is the requirement for faster signal processing technology. In this regard, all-optical processing plays a key role in eliminating optical-electrical-optical conversion, thus offering unmatched operation speed with reduced complexity and power consumption. This thesis focuses on high speed all-optical signal processing technologies based on innovative fiber-based interferometers, including Mach-Zehnder and loop mirror interferometers constructed by photonic crystal fiber (PCF), birefringent fiber and highly nonlinear fiber (HNLF). / We also investigated signal processing using nonlinear devices beyond those fiber interferometers. FWM is utilized for chirp magnification which was successfully applied to optical comb generation for obtaining optical OFDM signals. Optical comb generation with extinction ratio enhancement and flatness improvement is demonstrated utilizing a stimulated Brillouin scattering (SBS) based optical loop mirror. Clock recovery of OTDM-OOK signals has been successfully demonstrated over a wide range of bit rates using the SBS loop mirror. / With dispersion management inside the loop mirror interferometer, we have further proposed and demonstrated a modified DA-NOLM. The new device introduces a larger asymmetry in the propagation of the two interfering branches while maintaining a zero total dispersion in each of them. Consequently, pulse broadening is reduced and higher bit rate operation is supported. With the device, we have successfully achieved error-free two-channel DEMUX for 80-Gb/s OTDM signals. / Du, Jiangbing. / Adviser: Chester Shu. / Source: Dissertation Abstracts International, Volume: 73-06, Section: B, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2011. / Includes bibliographical references. / Electronic reproduction.
