Abstract: The switching dynamics of short pulses under the effects of intrapulse stimulated Raman scattering (ISRS) and intermodal dispersion is studied. It is found that ISRS can generally reduce the pulse width and slow down the pulses simultaneously. With numerical examples, we demonstrate that the pulse narrowing effect of ISRS can be weakened by the intermodal dispersion.
