本文提出了一种由左、右全混洗和空间光开关列阵组成的等效Omega网络;成功地设计了一种实现全混洗互连的低损耗,等程的光学组合棱镜.由两块光学组合棱镜和空间光开关列阵组合成的光学系统实现了全混洗交换光学互连网络,该光学互连网络已在实验中得到了证实.

The perfect shuffle/exchange Omega interconnection network is a free-space regular multistage interconnection network. It is one of great important networks to develop novel architectures of digital optical computer in parallel and data flow and optoelectronic hybrid computer in parallel multiprocessor system. This, paper presents a equivalent omega network which consists of left and right perfect shuffle interconnection as well as a spatial light switch device. A optical combination prism with the properties of low loss, and equal path length of all optical channels to implement perfect shuffle interconnection has be designed. The optical system of perfect shuffle/exchange Omega network composed of two optical combination prisms and a spatial light switch device is realized in our experiment.
