Abstract
We present details of a simple method, incorporating first-order perturbation theory, to analyze the birefringence exhibited by elliptical-core fibers by using an equivalent rectangular-core waveguide. The results from this method are compared with those obtained from the finite-element and another approximate technique to demonstrate the accuracy of this simple method. The method may be extended to analyze waveguides of arbitrary geometry.
