Abstract :
The effective-index method (EIM) with built-in perturbation correction is developed for the analysis of the vector modes of general rectangular-core optical waveguides. This method maintains the simplicity and the high efficiency of the conventional EIM, yet produces significantly more accurate results. Numerical examples for a wide range of waveguides are presented to demonstrate the accuracy of the method for the calculation of the propagation constants and the modal birefringence
