Description
We analyze a lifetime-broadened four-state, ladder-type four-wave mixing (FWM) scheme in the context of optical soliton formation. We show that a pulsed probe field and a pulsed FWM field of considerably different frequency can evolve into a pair of matched solitons with the same temporal shape and ultraslow group velocity (Vg/c∼10-3), i.e., two-color ultraslow optical solitons. In addition, we show regimes where two-color superluminal (Vg/c<0) optical soliton propagation may occur
