摘　　要：Crossbar网络是实现高速并行光学处理的一种最重要而有效的光交换网络结构。作为一种无阻塞网络,Crossbar网络具有简单性,易于实现控制,适合于构成光开关矩阵。总结和分析了近20多年来发展的Crossbar光交换网络,介绍了不同Crossbar光交换网络的原理、结构和性能,分析了Crossbar光交换网络的关键技术。目前光学互连网络的发展方向是实现集成大规模光互连。可以预见光学互连网络会朝着更加实用化的方向发展,并在其应用领域发挥越来越重要的作用。Crossbar network is one of the most important and effective structures to achieve high-speed parallel optical processing in optical switching networks. As a non-blocking network, crossbar network is simple, easy to control, and suitable for forming optical switch matrix. We summarize and analyze crossbar optical switching networks on the recent development for more than 20 years, describe the various crossbar principles, structures and properties of optical switching networks, and analyze the crossbar key technologies for optical switching network. The recent development direction of optical interconnection network is to achieve integrated large-scale optical interconnection. It is predictable that optical interconnection network will become more practical and play an increasingly important role in its application areas.
