一种灵活扩充的分块式纵横制光互连网络

提出了一种新型的具有灵活扩育能力的分块式纵横制光互连网络体系结构，并给出了该网络在最大扩充时光学子系统的物理实现及相应的一些实验结果。该体系结构中可采用自电光效应器件作为高速光调制器。采用在单块ＧａＡｓ基片上集成的场效应晶体管－自电光效应器件作为逻辑光开关器件。

A Scalable Optical Separated Crossbar Network

A novel, flexibly scalable optical separated Crossbar network configuration is proposed. Optical sub system is physically implemented. We present experimental results of the optical sub system. Network configuration of separated Crossbar employs the SEED devices as high speed optical modulators and the FET SEED device integrated on a single GaAs chip as optical logic array. This configuration solves the problem that a Crossbar is hardly scalable by employing flexible code rule and one, two or four FET SEED chips to provide scalable optical channel receivers. But the size of the separated Crossbar is limited within 32×32. This network configuration is especially promising in network computing application based on distributed computers. And it is competitive in realization of Cross connect matrix of SDH Cross connect system.
