Abstract
Recently, photorefractive (PR) spatial optical solitons have been the focus of considerable attention.1-6 Of particular interest are the so-called screening solitons that occur in steady state when an external bias voltage is appropriately applied to a PR crystal.2,3 These soliton states are known to occur when the drift term dominates in the expression of the space charge field. In a recent study,7 the effects arising from first-order diffusion terms have also been investigated. It was found that the PR soliton can experience adiabatically self-deflection that varies linearly with the applied electric field. However, recent experiments8 suggest that this self-deflection can exceed that predicted by theory,7 especially in the regime of quite high bias fields.
