We show that pulses undergoing wave breaking in nonlinear weakly dispersive fibers radiate, owing to phasematching (assisted by higher-order dispersion) of linear dispersive waves with the shock-wave front. Our theoretical results perfectly explain the radiation observed recently from pulses propagating in the normal dispersion (i.e., nonsolitonic) regime.

Abstract
We show that pulses undergoing wave breaking in nonlinear weakly dispersive fibers radiate, owing to phasematching (assisted by higher-order dispersion) of linear dispersive waves with the shock-wave front. Our theoretical results perfectly explain the radiation observed recently from pulses propagating in the normal dispersion (i.e., nonsolitonic) regime.File in questo prodotto:
