用一种简便的方法计算并分析了Jensen与Deering提出的两种非线性二波导耦合器,它们具有由两个非线性波导嵌入线性波导而成的类似结构,不同的是所用非线性波导材料分别具有二阶、三阶非线性.分析的结果有效地给出了耦合器的两个波导中强度和相位变化的信息,从而得到并比较了它们的开关特性,为设计二波导耦合器光开关提供了一种分析方法.
A simple method was used to calculate and analyze two kinds of nonlinear two-waveguide couple proposed by Jensen and Deering. They have a similar structure with two nonlinear waveguides embedded in linear waveguides. The difference is that the nonlinear waveguides used are respectively With the second-order and the third-order nonlinearity.The results of the analysis effectively give the information of the intensity and the phase change of the two waveguides of the coupler, so as to obtain and compare the switching characteristics of the two waveguides for the design of the two waveguide coupler optical switches An analysis method.
