Exact dispersion equations and expressions for TE-mode field distribution are obtained for two types of planar diffusion integrated optical waveguides: an Epstein asymmetrical profile and a profile consisting of a parabolic segment and an exponential part. The parabolic profile is considered as a limit case. The exact solutions are used to estimate the applicability and the accuracy of some approximate methods for analysis of planar ion-exchanged waveguides in glass
