Abstract
A theory on combined self-phase modulation (SPM) and stimulated Raman scattering (SRS) in optical fibres is given. The theory shows that Raman frequency conversion is not affected by SPM, and the phase shifts of pump and Stokes radiation are proportional to the input pump pulse. The variation of the linewidths Δν 1/2 of pump and Stokes pulses against pump peak powerP p is analysed numerically by fast Fourier transformation (FFT). The results show that the SRS has a small effect on the linewidth of pump light whenP p is small, and will saturate the increase in Δν 1/2 asP p becomes large. Discussion on output pump pulse shape makes the physical meaning of the variation of Δν 1/2 clear.
