Abstract :
New technique for analysis of multimode diffused channel optical waveguides is presented. The technique is based on mixing the impedance boundary method of moments and the effective index method. Dispersion characteristics are calculated for structures suitable for millimeter-wave and optical integrated circuits, such as channel waveguides with refractive index variations having stepped Gaussian, and exponential function profiles. The technique is verified by comparison with results available from other methods.
