Abstract
The Raman self-frequency shift of ultrashort pulses in dispersive optical fibers can be suppressed by cross-phase modulation from a copropagating pump pulse. In both analytical and numerical analyses, we show that the interaction of group-velocity dispersion, cross-phase modulation, and intrapulse stimulated Raman scattering results in a periodic rather than a progressive self-frequency shift.
