Abstract
The propagation of a square beam and a Gaussian beam along the interface of two photorefractive crystals is studied theoretically. Both of the crystals have a diffusion nonlinearity of the gradient type (with a sign opposite that of the diffusion nonlinearity), which is able to balance the self-bending of the beams and hence to produce a photorefractive surface wave. A comparison of this wave with the symmetrical and antisymmetrical surface waves propagating along the photorefractive crystals’ interface is also given.
