Author Affiliations +
In steady state and two dimensions the distributions of the nonlinear refractive index in a photorefective crystals under the conditions of supporting low intensity spatial solitons are studied. It is shown that steady state spatial bright solitons of modulated ThM00 mode Gaussian waveform can form and induce planar array waveguides in photorefractive crystal. The effects of modulating conditions, the intensity of spatial solitons and the external bias electric field on profile of refractive index of the array waveguides is investigated.
