We show that, under certain conditions, modulation instability in nonlinearwaveguides gives rise to the usual double-sideband spectral structure, but witha Raman gain profile. This process is enabled by the energy transfer from a stronglaser pump to both Stokes and anti-Stokes sidebands in a pseudo-parametric fashion.We believe this striking behavior to be of particular value in the area of Raman-basedsensors which rely on sensitive measurements of the anti-Stokes component.
