Abstract
A method is presented whereby the refractive index profile of a planar, surface, dielectric optical waveguide may be reconstructed from a measured set of effective refractive indices in a way that is consistent with the Helmholtz equation. Profiles are compared with those obtained by conventional techniques which use the Wentzel-Kramers-Brillouin (WKB) approximation
