The mutual effects of stimulated Raman scattering and four- wave mixing (FWM) in phosphosilicate fibers is studied experimentally and theoretically. It is found that the output spectra depend on the launched condition strongly. When only one mode is excited in the fiber, the output spectrum is determined by the competition of stimulated Raman scattering between the SiO₂ and P₂O₅. The SiO₂ Raman line is dominative with lower pump power or using of short length fiber. While the pump power is increased or the long fiber is used, the P₂O₅ Raman line increased and the SiO₂ Raman line is suppressed. When two modes are excited in the fiber, the effects of four-wave mixing is dominative and the spectrum only consist of lines of FMW-assisted Raman scattering of SiO₂.
