Photorefractive Parametric Interaction of Volume and Leaky Optical Waves in Planar Waveguide on Lithium Niobate

Abstract

In optical waveguides with high photorefractive sensitivity the frequency - degenerate four - wave interactions are observed as well as in optical nonlinear materials [1], Several types of interactions nonanalogous for the processes in volume materials, can be realized in optical waveguides because of specifics of their properties.
