Polarization switching of stimulated Raman scattering in optical fibers by dual-frequency pumping

Abstract:
Experiments are presented showing that under dual-frequency, orthogonal-polarization pumping, stimulated Raman scattering in optical birefringent fibers can be suppressed in one of the two fiber axes. For relatively small-frequency spacing and group-velocity mismatch between the pumps, Stokes light is suppressed along the polarization direction of the highest-frequency pump, owing to the orthogonal component of the Raman gain.
