Raman blueshift of optical dark solitons

摘要

A novel direct perturbation approach to the self-induced Raman effect on dark optical solitons is discussed. The seeming breakdown of the adiabatic assumption found previously is overcome. A complete adiabatic solution is given, confirming previous numerical and analytical results for the Raman blueshift on a more rigorous basis.
