Abstract

The photorefractive gratings formation in planar waveguides has been described in Refs. 1-3. LiNb03 single crystal doped of the impurities Fe or Cu was used as substrate of photorefractive waveguides [4]. Photorefractive gratings formation in that waveguides is due to the photovoltaic effect.
