Abstract

The effect of the detailed Raman cross section on the evolution of ultrashort solitons is considered. It is shown that the gain contribution leads to the self-frequency shift, whereas the phase contribution, which is usually determined by use of the Kramers–Kronig relations, has little visible effect. This result is consistent with the hypothesis that solitons are robust in the presence of Hamiltonian deformations.
