Paper Abstract

We present a new approximation for obtaining the analytical dispersion relations of planar waveguides with arbitrary index profile of practical interest. In our method, two substantial improvements over the conventional WKB method are presented. The numerical comparisons show a good accuracy of the results even for a single-mode waveguide or close to the turning point.
