摘要：

A method of calculating the complex propagation constant of a planar optical waveguide under very general but weakly guiding conditions is derived. The method, based on Galerkin's formalism using Hermite-Gaussian basis functions, allows a nonuniform and complex refractive index profile. The real and imaginary parts of the index are allowed to vary independently and arbitrarily as a function of position. The planar waveguide is used so the results can be compared with exact solutions. The method is more general than this, however, and can be used with any geometry. The results are inherently stationary.
