Abstract

Dark spatial solitons are self-supported dips imposed on uniform background beams. The physical mechanism of their formation is based on the balanced counteraction of beam diffraction and self-defocusing. In this work we study the spatial evolution of ring dark solitary waves (RDSWs) in nonlinear media possessing saturable self-defocusing nonlinearity. Such type of nonlinear response was observed in photovoltaic media [1].
