Eigenvalue computation in slab waveguides with some perfectly matched layer

Abstract

In this paper, based on the Rayleigh Quotient Iteration method, a new treatment is developed to solve the complex eigenvalue problems, which arise from the analysis of the optical wave propagation in Slab waveguides with some perfectly matched layers. Numerical examples illustrate that this treatment is more efficient and feasible. It can be widely applied to the numerical calculation of optical wave propagation in open waveguides.
