Research Abstract |
This project investigated the three key design issues of all-optical routers, namely the designs of optical switch, optical buffering element and overall router architecture. About optical switch designs, we explored both the designs basedon directional coupler(DC) technology and the designs based on Arrayed Waveguide Grating(AWG) technology. About the optical buffering element designs, we explored the first-in-first-out(FIFO) shared optical buffer, last-in-first-out optical(LIFO) buffer and optical multiplexers. About the overall optical router architecture design, we explored for the first time the shared optical router architecture. We have also developed the efficient packet control and scheduling algorithms to maintain packet order in shared optical router.
