Abstract
A modified space-charge field is presented for biased photorefractive-photovoltaic crystals. When the external electric field is absent, there prevails the space-charge field of photovoltaic solitons in closed circuit and open circuit. The self-deflection of steady-state bright spatial solitons arising from the diffusion effects is investigated using perturbation analysis for the low-amplitude regime in biased photorefractive-photovoltaic crystals. Predicted are the center of the optical beam moving on a parabolic trajectory and the central spatial frequency component shifting linearly with the propagation distance. The soliton wavelength division multiplexing device may be made by using the self-deflection of the spatial solitons in biased photorefractive-photovoltaic crystals.
