Modal analysis of dielectric optical waveguides based on Chebyshev polynomials

Abstract

We propose an accurate and efficient numerical method to compute the modal characteristics of dielectric optical waveguides. The present method represents electric and/or magnetic fields by Chebyshev polynomials based on a multidomain spectral collocation scheme. Compared with analytical solutions and the published results using rigorous numerical methods, our results show excellent agreement. © 2005 Wiley Periodicals, Inc.
