Resonant radiation and collapse of ultrashort pulses in planar waveguides.

Opt Lett 2005 Mar;30(5):525-7

Department of Physics, University of Bath, Bath BA2 7AY, UK.

We study the spatiotemporal dynamics of ultrashort pulses close to a point of zero group-velocity dispersion in planar waveguides with focusing nonlinearities. We find that the process of pulse collapse enhances the emission of so-called resonant radiation, providing an efficient mechanism of energy transfer from solitonic to dispersive waves and leading to suppression of the collapse.
