Paper Abstract

We start from Kukhtarav equations and Gauss's law which describe the photorefrective effect in a photorrefractive medium in which electroncs are the sole charge carries, plus the wave equation for the slowly varying amplitude of the optical field , In steady state and two dimensions the distributions of the nonlinear refractive index in a photorefective cystals under the conditions of supporting low intensity spatial solitons are studied theoretically. It is shown that steady state spatial bright solitons of TEMn0(n=2,2,3...)modes and modulated TEMn0 mode Gaussian waveform can form and induce planar array waveguides in photorefractive crystal.
