An Improved Method for the Exact Analysis of Multilayer Optical Waveguide with Complex Dielectric Constants
The theoretical study on optical characteristics of multilayer optical waveguides with complex dielectric constants involves great quantities of computation to sovle the complex transcendental eigenvalue equation. In this paper an improved and generalized formula for calculating the complex modal refractive indeces of guided modes is presented. In combination with iteration method very exact results can be capidly obtained even for high loss or high gain structrues. The procedure is illustrated on 4 layer
