新型大容量光交换的关键技术和应用

[摘要] 为了实现更大容量的光交换，需要突破矩阵光开关的规模化“瓶颈”。微机电光开关（MEMS）、循环阵列波导光栅（CAWG）、波长选择开关（WSS）等具有多端口规模化特征，能够实现良好的模块化扩展，具有使交换容量倍增的潜力。MEMS、CAWG、WSS在大型数据中心、大容量光交叉连接、灵活栅格光分插复用等系统的应用中具有独特优势和良好前景。

[Abstract] To achieve high-capacity optical switching, the optical switch matrix needs to be investigated. The micro-electromechanical system (MEMS) switch, cyclic array waveguide grating (CAWG), and wavelength selective switch (WSS) have the advantages of multiport dimensions and expansibility to a larger modular scale. They have potential applications in data center network, optical cross-connect, and flexible gridless optical add-drop multiplexer.
