Temporal Bragg gratings produce broadband, frequency-agile parametric gain with higher amplification from high-index modulation layers, strong sub-Bragg versus supra-Bragg asymmetry, and a transition to continuum gain via multi-phase-matching in the extreme sub-Bragg limit.

Temporal Bragg Gratings: Broadband Reconfigurable Parametric Amplifiers
Temporal Bragg gratings produce broadband, frequency-agile parametric gain with higher amplification from high-index modulation layers, strong sub-Bragg versus supra-Bragg asymmetry, and a transition to continuum gain via multi-phase-matching in the extreme sub-Bragg limit.
