In communication systems, the need for high bandwidth interconnects and efficient distribution of large amount of data is very essential. This thesis work addresses all-optical packet switching issues in the field of reconfigurable optical interconnection networks for high performance embedded systems. The recent research conducted at the Halmstad University, on high performance embedded systems, focuses on the optical interconnection techniques to achieve ultra high throughputs and reconfigurability at the system level. Recent research in the field of optical interconnection networks for applications like switches and routers for data and telecommunication industry and parallel computing architectures for embedded signal processing use optical to electrical conversion to switch packets. This conversion scales down the enormous bandwidth capacity of the optical communication channels to electronic processing rates. To maintain the high throughputs all over the interconnection networks, the optical packets need to be maintained in optical state and switched to different part of the interconnection network. To achieve this goal, all-optical packet switching architectures are studied. The study is concluded with a positive outlook towards alloptical switching technol...
