摘　　要：设计了一种能直接与单模光纤阵列相耦合的多模干涉 (MMI)型光开关。给出了MMI型光开关各组成部分的工作原理 ,并用导模传输分析法 ,模拟了 1× 4MMI型光开关的四种不同的开关状态 ,在此基础上完成了 1× 4和 4× 4MMI型光开关的设计。最后根据所确定的器件结构参数 ,用有限差分光束传输法分析了器件结构参数对器件性能的影响。A GaAs multi-mode interference optical switch which can be coupled with single mode fiber has been designed.First we analyze the operating principle of each component of the MMI optical switch.Then we use the guided-mode propagation analysis method to simulate all the switching state of the 1×4 MMI switch so as to design the 1×4 and 4×4 MMI optical switch. On the basis of predefined waveguide parameters, we use the finite difference beam propagation method to analyze the effect of the parameters on the device.
