摘要：

In this paper we present the application of a novel fully vectorial and three-dimensional computational method for planar devices to simulation of electromagnetic modes in classical and photonic-crystal-based VCSELs. We show the mathematical basis of the method and present results of computations of a resonant wavelength, optical losses, and a threshold gain of a classical arsenide VCSEL with oxide confinement and also of a purely photonic-crystal confined one. Furthermore we analyze the analytical reduction of computational domain to two dimensions in axisymmetric geometries with cylindrical-wave expansion, discuss the mathematical problems which occurs in such coordinates and suggest a method to overcome them.
