Publikováno v: Journal Of Physics Conference Series

The possible variants of experimental observation of light diffraction on periodically poled domain structures (PPDS) in the lithium niobate crystal with 180-degree domain Y-walls are considered. We experimentally investigated isotropic and anisotrop

Field structure in a photorefractive holographic grating in a planar waveguide

Autor: E. N. Savchenkov, Yu. R. Salikaev, S. M. Shandarov

Publikováno v: Russian Physics Journal. 36:1086-1092

A theoretical investigation is made of the field structure in a holographic grating formed by TE0 modes in a planar photorefractive waveguide by the photogalvanic recording mechanism. Waveguides with three characteristic refractive index profiles are
