Abstract
We show the possibility of generating gain-assisted superluminal optical solitons in a room-temperature three-state active Raman gain medium. We demonstrate both analytically and numerically that under appropriate conditions a signal field of very low intensity can evolve into a stable shape-preserving wave form that propagates with superluminal velocity. Shape recovery of superluminal solitons after collision is also demonstrated numerically.
