Abstract

An accurate and fast propagation method for dielectric passive and active waveguides is a useful tool for OEIC design. The propagation constant, the intensity distribution, optical transmission/ reflection and the coupling efficiency characterize a device and can be calculated with several methods. However, large refractive index steps both in the propagation direction (gratings, BUTT-coupling), as well as in the transverse direction (multi waveguide structure, vertical coupler) lie above the common calculation limits of most optical modelling methods.
