All-optical label swapping strategies for spectral amplitude code labels in packet-switched optical networksHabib, Christian. January 2009 (has links)
There is currently much work focused on developing packet-switched optical networks to overcome the limitations of existing optical networks. Switch design for packet-switched optical networks is particularly challenging, in part due to the lack of a practical optical memory system. As a result, optical labels and all-optical label processing have attracted much attention. This thesis examines a crucial label processing component of an optical packet switch, namely the label swapper. / In this thesis, three different tabletop topologies for low-cost all-optical swapping of spectral amplitude code labels for packet-switched networks are examined in a proof-of-concept phase. The first uses cross-absorption modulation in an electro-absorption modulator within a semiconductor fiber ring laser (SFRL), the second uses cross-gain modulation (XGM) in a semiconductor optical amplifier (SOA) within an SFRL, and the third makes use of XGM in a SOA as well as injection locking in a Fabry-Perot laser diode for wavelength conversion. The benefits and limitations of each approach as well as future improvements are discussed. Building on these results, a high-performance integrated version of XGM swapper is designed, simulated, and masks are produced for fabrication using indium phosphide technology.

Personal Information Environment: A Framework for Managing Personal Files across a Set of DevicesMOHAMMAD, ATIF 06 August 2009 (has links)
The advancement in computing in the last three decades has introduced many devices in our daily lives including personal computers, laptops, cellular devices and many more. The data we need for our processing needs is scattered among these devices. The availability of all the scattered data in the devices in use associated to an individual user as one is achieved in a Personal Information Environment. Data recharging is a technique used to achieve a Personal Information Environment for an individual user using data replication.
In this thesis, we propose a data recharging scheme for an individual user’s Personal Information Environment. We study the data availability to a user by conducting a simulation using the data recharging algorithm. This data recharging approach is achieved by using master-slave data replication technique. / Thesis (Master, Computing) -- Queen's University, 2009-08-06 00:18:00.19
