利用传统成熟的偏振控制技术,设计了一种由偏振光分束器、相位型空间光调制器、反射镜和四分之一波片构成的3×3光开关。该光开关具有结构紧凑规整、功能的实现与信号光的偏振态无关以及可以完成双向交换等特点。根据其路由控制表对该3×3光开关交换模块功能的实现进行了分析,结果表明,通过对各相位型空间光调制器状态的调整,控制通过其信号光的偏振态,完成信号光的路由,该交换模块可以完成输入信号光的全排列无阻塞输出与交换。同时,该交换模块具有一定的扩容和重构能力,对于构建大规模的交换矩阵具有一定的作用。
A 3 × 3 optical switch composed of a polarization beam splitter, a phase spatial light modulator, a reflector and a quarter-wave plate is designed by using the traditional mature polarization control technology. The optical switch has the advantages of compactness and structure, the realization of the function is independent of the polarization state of the signal light, and the bidirectional exchange can be completed. According to the routing control table, the realization of this 3 × 3 optical switch module is analyzed. The results show that by controlling the state of each phase spatial light modulator, the polarization state of the signal light is controlled to complete the signal light Routing, the switching module can complete the entire input signal light non-blocking output and exchange. At the same time, the switching module has a certain capacity of expansion and reconstruction, to build a large-scale switching matrix has a certain role.
