摘　　要：未来的高速和高度灵活的光分组交换网络要求开关速度达到纳秒量级且集成度高的大规模空间光开关矩阵。在分析了基于半导体光放大器的常用结构形式的光开关矩阵存在规模局限性的基础上 ,综述了新型的可实现大规模集成的基于半导体光放大器的光开关矩阵的基本原理和研究现状。Optical space switch arrays that can offer nanoseconds switch time as the devices are integrated to larger and larger arrays will meet the demand of high speed and agile routing of packets in future optical packet switching networks. Under the analysis of scalable limitations toward ordinary optical space switch matrix based on semiconductor optical amplifier,basic principles of novel arrays which can be easily scaled to significantly larger sizes are presented,as well as their progress.
