Abstract:	Propagation of femtosecond light pulses spectrally centered at the 1s-exciton resonance in a semiconductor is studied analytically and numerically. Soliton-like propagation is demonstrated for pulses with the input area exceeding a certain threshold. This phenomenon is shown to be different from the self-induced transparency in atomic systems and associated with the formation of the resonant solitons due to exciton-exciton interactions.
