Abstract

The weakly guiding approximation is the basis for the most well-known methods and their extensions for evaluation of optical waveguide parameters. However, solutions of scalar wave equations are not exact, and there are some applications requiring more high accuracy. It is obviously, polarization effects, occurred by guiding properties of the optical fibers, must be taken into account to improve the accuracy. Thus, "polarization correction" term, described by A. Snyder, must be added to scalar propagation constant. Method, based on Gaussian approximation, for calculation of polarization correction to the any order mode propagation constant in weakly guiding optical fiber with an arbitrary coaxial index profile is proposed. Results of error reducing by adding of correction to propagation constant, obtained by scalar wave analysis, are demonstrated. First and second order derivatives of the correction are obtained and represented.
