Paper Abstract

Channel waveguides produced parallel to the z-axis in x as well as y-cut LiNbO3 by Ti indiffusion are found to display severe optical damage in the form of coupling between TE and TM modes for power levels in the range of 1-100 microwatts at wavelengths of .633 and .488 microns. Previously, this orientation was thought to display little or no damage. The effect is manifest by both a steady state power dependent transfer of as much as 30% optical energy between orthogonally polarized modes as well as a transient regenerative switching between these modes seen only in x-cut samples subjected to continuous optical throughput at the above power levels for a period of 8-24 hours. A model of the observations is proposed based on photorefractive perturbations
