Abstract :
A finite-difference formulation is described for analyzing diffused dielectric channel waveguides with arbitrarily varying two-dimensional index profiles and arbitrary index difference levels. The method allows the calculation of the complete set of hybrid modes, without nonphysical, spurious solutions. Hybrid-mode-dispersion curves for integrated optical channel waveguides with graded index profiles of practical interest are presented.<>
