Abstract

Galerkin´s method with the sine basis function is applied for accurate analysis on the mode propagation problem in integrated optical waveguides. The method is based on a tangent-type variable transformation at spatial coordinates. The dispersion relations and modal field distributions of guided waves in rib waveguides with trapezoidal cross sections are obtained.
