Abstract
We consider the problem of continuous-wave parametric amplification by a strong pump of a signal wave tuned to a Bragg grating. We find spectral regions of enhanced and reduced gain compared with gain in a uniform medium. The changes are explained by local bending of the dispersion relation induced by the grating. Calculations of pump powers suggest that the effects may be observed in optical fiber Bragg gratings.
