Abstract

With one weak pulsed probe field, one strong pumping field, and one coupling field, superluminal optical solitons are formed in a lifetime-broadened Λ-type atomic medium with two-folded levels. The corresponding group velocity of the solitons can be larger than the vacuum light speed c; i.e., superluminal solitons can be presented.
