Calculation of the Complex Propagation Constant of Nonlinear Waves in a Three Waveguide Structure

Abstract

In this Paper we have implemented a simple technique based on Davidenko's method and another perturbation method in order to solve a complex nonlinear dispersion equation in a lossy nonlinear waveguide. Both methods are used to compute the dispersion equation for TE waves guided by a dielectric film bounded by each side with complex nonlinear dielectric media.
