EFFECTS OF SELF-STEEPENING AND SELF-FREQUENCY SHIFTING ON SHORT-PULSESPLITTING IN DISPERSIVE NONLINEAR MEDIA

We characterize the propagation of short optical pulses through disper sive media with a cubic self-focusing nonlinear polarization, which in corporates self-steepening and self-frequency shifting. These effects can significantly affect pulse propagation dynamics, both in the norma l but especially in the anomalous dispersion regimes. The nature of th e dynamics is significantly different in the two regimes.
