Abstract

Mode index measurements of optical slab waveguides fabricated by proton-exchange with pyrophos-phoric acid in z-cut LiNb03 have been made. The index profile is approximately a step with an index increase of .131 at T = 200°C. In addition to establishing formulae for the effective diffusion constant (De) and guide depth (d) for a given diffusion temperature and time, an investigation of the often neglected anisotropic nature of these wavercuides is presented.
