FIG. 1.

Measured broadband Raman gain spectra with pump pulses. (Left) Raman gain spectra produced by pump pulses with the indicated (input) peak power levels. (Right) Normalized spectral densities of pump pulses at the waveguide output.

FIG. 3.

Impact of nonlinearities on the pulse spectrum in a silicon waveguide: (a) , and (b) , . Left to right: input spectrum; output spectrum with the action of Kerr nonlinearity and TPA; output spectrum with the action of Kerr, TPA, and FCR; output spectrum with the action of Kerr, TPA, FCR, and FCA.

Image of FIG. 4.
FIG. 4.

Simulated Raman gain spectra at the indicated pump-probe delay (pump:, ). Negative delay corresponds to probe on the leading slope of pump. Dotted lines mark “break-even” levels for the pump on/off gain. For delay, the on/off gain is largest, and the spectral shape resembles that measured experimentally.
