摘要: A simple first order perturbation approach to study the birefringence of highly elliptical core weakly guiding optical waveguides is presented. The index profile taken be a rectangular waveguide for which exact scalar wave modes are known. Results obtained by present analysis agree very well with one numerical calculations.
