Abstract

本发明公开了一种波长选择开关和控制波长选择开关中的空间相位调制器的方法。该波长选择开关包括：第一分波合波器件，用于将输入的多波长光信号在空间上分离成多个单波长光信号；空间相位调制器，用于分别改变多个单波长光信号包括的各单波长光信号的传输方向，其中，空间相位调制器还用于将多个单波长光信号中的第一单波长光信号分离为第一光束和第二光束，该第一光束入射到波长选择开关的输出端，该第二光束入射到波长选择开关的监测端；光电探测器，设置在监测端，用于接收该第二光束；性能监测器件，用于对接收到的该第二光束进行性能监测。本发明实施例的波长选择开关和方法，能够对单波长光信号进行性能监测，并能够减小系统体积和成本。
