Design of Next Generation All-Optical Router

本课题研究了全光路由器的三个关键设计问题，即光开关设计、光缓存器件设计和路由器总体结构设计。在光开关的设计方面，我们探讨了基于定向耦合器（DC）技术的设计和基于阵列波导光栅（AWG）技术的设计。在光缓存器件的设计方面，我们研究了先进先出（FIFO）共享光缓存器、后进先出（LIFO）光缓存器和光复用器。在光路由器的总体架构设计中，首次探讨了共享光路由器的架构。我们还开发了有效的分组控制和调度算法，以维持共享光路由器中的分组顺序。

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.
