New method for analysis of planar optical waveguide with arbitrary distribution of dielectric constant profile

Abstract:

A new method is proposed for the analysis of singlemodes and multimodes planar gradient waveguides, with arbitrary distribution of the constant dielectric ε(y). The method designated αk permits the calculation of the propagation constants, critical frequencies and the TE and TM modes. The method allows one to determine the distribution of ε(y) from experimental model or from a theoretical model. In this work two theoretical models of the distribution of ε(y), that permit to simulate and analyze the assorted cases of planar optical waveguides are proposed. The αk method, can be used to draw the refractive index profile, based upon the values of the propagation constants obtained experimentally.
