摘　　要：曲折光线法和解波动方程是分析平面光波导的基本方法。若将两者有效的结合 ,则分析问题会十分简便。本文首先用解波动方程的方法求出非对称波导的模式方程 ,然后结合曲折光线法得出的模式方程导出对称波导的模式方程。The solving of wave equations and tortuous ray method are fundamental methods of analysing plane optical waveguiding.Combining these two methods effectively can make analysis very simple.The procedure is as the following:First,the methods of solving wave equations is used to solve the mode equation of nonsymmetry waveguiding.Second,the solutions above are combined with mode equations gained by tortuous ray method to produce the mode equation of symmetry waveguiding.Finally,the graphic method is used to solve mode equations.
