Abstract :
Self-action of the light beams propagating in a planar photorefractive waveguide on the base of sillenite crystals is investigated. The numerical simulations demonstrate the possibility of soliton-like beam propagation in planar Bi12TiO20/Bi12SiO20 waveguide fabricated by epitaxy. In our study we assume orientation of a (100)-cut Bi12TiO20 crystal in which the external field is applied parallel to the [100] axis (z waveguide axis) and optical wave front propagates along the [011] direction. The wave equations that describe the evolution of the amplitude distribution of light beam are derived.
