Locality vs. Nonlocality of (2+1)-dimensional Light-induced Space-charge Field in Photorefractive Crystals

Calvo, G F; Agullo-Lopez, F; Carrascosa, M; Belic, M; Krolikowski, Wieslaw

Description

A novel analytical description of the nonlocal anisotropic space charge field, induced by (2+1)D localized light beams in photorefractive crystals, is introduced. Closed-form expressions for the space-charge field induced by circularly symmetric beams are obtained. Also, on the basis of our formulation, numerical simulations of the beam dynamics are performed and compared with those corresponding to a local modeling of the space-charge field.
