VECTOR PHOTOREFRACTIVE SPATIAL SOLITONS

We derive vector soliton solutions for photorefractive media in which the refractive-index perturbations must be treated as tensors. The two polarizations of the vector solitons may be coupled through the space -charge field alone and/or through cross terms in the electro-optic te nser, which requires phase matching and specific configurations. We an alyze bright planar vector solitons and verify their stability. (C) 19 95 Optical Society of America
