本文讨论了在三层平板介质波导中横电波的传播问题 .三层平板的芯区是 Kerr介质 ,其折射率平方 n2 的剖面分布随 x作抛物分布 .本文将应用伽辽金方法 ,求出赫姆方程的第 1次和第 2次近似的解析解 .
In this paper, the propagation of transverse electric waves in a three-layer slab waveguide is discussed. The core of a three-layer slab is a Kerr medium, and the distribution of the refractive index squared n2 is parabolic with x. By using the Galerkin method, Analytic solutions of the first and second approximations of the Hermite equation.
