ABSTRACT:
Nonlinear pulse reshaping for optical fiber transmission systems. A procedure utilizing nonlinear amplifying loop mirrors for recovering soliton pulses nonadiabatically deformed by losses is described. Input pulses are mapped into output pulses for segments of optical fiber followed by a combination of linear and nonlinear amplification. For a wide range of amplifier spacings, it is numerically established that a single optimal input pulse of soliton shape exists for each such spacing which is well recovered at the output of the amplifier, containing only .about.3% of continuous radiation.
