Paper Abstract

A technique was developed that uses bulk and effective indices measured at several wavelengths to determine index profiles in slab and channel waveguides. This technique involves the minimization of a functional J used to match the square of measured effective indices with those calculated. Effective indices are calculated from a modal analysis of a Galerkin type. J is minimized with respect to a number of parameters that are used to describe the refractive index appearing in the reduced wave operator and, in this way, the "inverse problem" of determining index profiles from measured effective indices is solved. Results are reported for slab and channel waveguides.
