Abstract

We determine, by a photoinduced light scattering study, that the increase of photorefractive sensitivity of the proton exchange waveguides in lithium niobate crystals is more than 3 orders of magnitude as a result of copper doping under certain conditions. This increase is determined to be due to the nonphotovoltaic contribution to photorefraction with a short responsiveness time.
