摘要： The coupling between two mutually incoherent optical beams that propagate collinearly in open-circuit photovoltaic photorefractive media is investigated. It is shown that an incoherently coupled bright—dark spatial soliton pair can be formed due to photovoltaic effect. The physical properties of such a soliton pair are also discussed.
