An analytical model describing refractive index profiles in ion‐exchanged glass waveguides is presented. Polarizability, volume, and stress‐state changes are accounted for. Index distribution is given in terms of known or measurable physical parameters. Model predictions compare favorably with experimental results of field‐assisted ion‐exchanged waveguides fabricated in 7740 borosilicate glass. Experimental characterization of the index changes includes prism coupling, microprobe, and photoelastic measurements.
