提出了一种新型的具有灵活扩充能力的分块式纵横制（Ｃｒｏｓｂａｒ）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（ＳＥＥＤ）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（ＦＥＴ－ＳＥＥＤ）作为逻辑光开关器件。这种分块式网络体系结构，可以灵活地采用编码规则和选择一块、二块或四块场效应晶体管－自电光效应器件来提供可扩充的光接收模块的数目，解决了常规纵横制网络不易扩充的问题。但该种网络的最大规模为３２×３２。这种网络体系结构用在构造分布式多个计算机组成的网络计算应用中特别理想，在同步数字系列交叉互连系统的交叉连接矩阵的实现中也很有竞争力。
A novel Crosbar optical interconnection network architecture with flexible expansion capability is proposed. The physical realization of the optical subsystems and the corresponding experimental results are also given. In this architecture, a self-electro-optic effect (SEED) device can be used as a high-speed optical modulator using a field effect transistor-FET (SEED) integrated on a single GaAs substrate as a logic optical switching device. This split-network architecture provides the flexibility to use coding rules and select one, two, or four field-effect transistors - self-electro-optic effect devices to provide the number of scalable optical receiver modules that address the challenges of conventional crossbar networks. Expanded question. But the largest of these networks is 32 × 32. This kind of network architecture is particularly ideal for network computing applications composed of distributed multiple computers and is also very competitive in the implementation of the cross-connect matrix of a synchronous digital hierarchy cross-connect system.
