摘要：

Light propagation in semiconductor amplifiers is investigated numerically for femtosecond pulses whose frequency spectra are fully inside the gain region. Whereas amplification is observed for low-intensity pulses, lossless propagation and even pulse absorption are found for large input intensities. These novel features arise from the competition between amplifying and absorbing states in the semiconductor continuum.
