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 tensor, which requires phase matching and specific configurations. We analyze bright planar vector solitons and verify their stability.
