Abstract
Recently a transverse magnetic field formulation of the finite element method for solving lightwave propagation in lossless optical waveguides was demonstrated using only two components of the magnetic field. We extend this formulation to include loss in the waveguides, and compare the results from this formulation with those of other formulations for three different types of waveguides. Our results from the new approach show good agreement with those from previously published data. No perturbation technique is needed to arrive at these results.
