Abstract :
The combined method of integral equation - finite elements (IEM-FEM) has been developed for calculation of optical dielectric waveguide properties. The method is applicable for optical dielectric waveguides with arbitrary core geometry and arbitrary distribution of core index of refraction and the constant cladding index. The cutoff frequencies are obtained for rectangular, elliptical, "rounded rectangle" waveguides and waveguides with concave core shape for aspect ratio from 1.0 to 100.0.
