Modes in diffused optical waveguides (parabolic and Gaussian models)

Contributed Papers


A simple analytical description of diffused optical waveguides by a Gaussian refractive index profile is proposed and compared to a parabolic one. Propagation constants and fields are obtained in terms of well-known functions only. The models are experimentally verified by measuring the mode spectrum of waveguides formed by thermal diffusion of silver ions into glass. These models yield a method to obtain guide parameters from mode spectrum.
