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.
