一种全光开关及任意比能量输出光分束器的设计

摘要

基于光子晶体非线性Kerr效应设计了一种结构简单的任意比能量输出光分束器，通过控制抽运光的强度来控制端口能量输出比。该结构还可以实现控制光传输的动态开关作用，并且具有插入损耗低、无串扰、信号光的开/关两个状态下的透射率相差非常大的特点，因此该光开关具有很高的开关比。%According to the nonlinear Kerr effect of photonic crystal, we design a simple structure with arbitrary proportion of energy output, which can be controlled by the pump intensity. At the same time, the structure can also realize the dynamic control of optical switch function, and has low insertion loss, crosstalk, two states of the signal light on/off. Therefore the light switch is of high efficiency.
