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
