Abstract
Parametric amplification of pulses in Bragg gratings is investigated numerically. Gain is observed for a much larger range of parameters than in uniform media. This is explained in terms of grating-assisted phase matching. In contrast to that for cw results, the input signal pulse need not be tuned to a particular frequency. Rather, through cross-phase modulation the signal self-locks to the correct frequency for growth.
