Abstract

Intense light pulses propagating through optical fibers are affected by a variety of third order nonlinear effects which appear at approximately equal laser powers. While self- and cross-phase-modulation (SPM and XPM) lead to spectral broadening, stimulated Raman Scattering (SRS) and four-wave mixing (FWM) cause pump pulse depletion and generate pulses at new frequencies. As a parametric process FWM requires phasematching, whereas for SRS this condition is automatically satisfied. Most of the research work has been dedicated to investigate the effects of SRS and FWM independently^[1] even though they may occur simultaneously.^[2]
