Spatial soli tons have been extensively investigated recently, in large part because of the potential use of these phenomena for optical computing and processing applications. Dark spatial solitons have been observed in Na vapor and various thermally nonlinear liquids1. Bright spatial solitons have been reported in glass waveguides2. In this talk, we will report the first observation of dark spatial solitons in technologically relevant bulk semiconductors on picosecond timescales. Our experimental results are consistent with theoretical predictions of various propagation parameters for dark solitons, supporting our interpretation of the observations.
