Abstract
We theoretically investigate slow light via stimulated Raman scattering, paying special attention to the picosecond regime where chromatic dispersion and cross-phase modulation must be considered. In addition to the control of the Raman pulse walk-off, we demonstrate that the cross-phase-modulation-induced frequency chirp can also be all-optically tuned via Raman slow light. We further demonstrate that this new implication is a consequence of the fact that the group velocity is significantly more affected than the phase velocity in slow-light media.

Slow and fast light (SFL) can be achieved by using a medium with a frequencydependent absorption or gain or by using other mechanisms such as atomic resonances with narrow electromagnetically induced transparency (EIT) windows, coherent population oscillations (CPO), and laser-induced amplifying resonances [1]
