Abstract: This paper describes self-phase modulation of an intense pulse that leads to spectral broadening that in combination with the filter, may compensate for the continuous frequency shift that is induced by the acousto-optic (AO) modulator. One may expect that optical fiber solitons are spontaneously generated as a result of the balance between dispersion, nonlinearity and filtering whenever a dispersive element is included in the cavity.
