Abstract:	We present an interferometric way to generate dark spatial solitons by propagating two coherent beams in a photorefractive Bi₁₂TiO₂₀ crystal under application of an external electric field. Our results shown that the initial width, initial separation, and relative phase between the beams allow to control the type of dark soliton generated.
