Surface Waves at the Interface of a Photorefractive Crystal and a Medium with Positive Kerr Nonlinearity
С. Е. Савотченко
Abstract
The types of nonlinear surface waves with extraordinary polarization arising at the interface between a photorefractive crystal and a medium with positive Kerr nonlinearity are described. It has been shown that nonlinear surface waves of two types with an asymmetric profile can exist in such a system. Waves of the first type damp when moving away from the interface into the depth of the photorefractive and Kerr crystals without oscillations, while waves of the second type damp into the depth of a photorefractive crystal with oscillations. Dispersion relations have been obtained and the conditions for the existence of all described types of waves have been written depending on the optical characteristics of the crystals.
