| Abstract: | We present a systematic study on the formation of ultra-slow
bright and dark optical solitons in highly resonant media. By
investigating four life-time broadened atomic systems, i.e.,
three-state Λ-type and cascade-type schemes, and four-state
N-type and cascade-type schemes, we show that the formation
of such ultra-slow solitons in cold atomic systems is a fairly universal phenomenon. |
