Abstract

Spectral evolution of a laser beam propagated in a planar waveguide filled with a Kerr medium is studied. A significant spectral broadening appears at the soliton threshold power. This broadening becomes asymmetric on the Stokes side in an excitation higher than two times the soliton threshold. We show clearly that self-phase modulation and stimulated Rayleigh scattering contribute together to this broadening and prove that the later limits the generation of a high-order soliton.
