Effect of Stimulated- Raman-Scattering on Modulation Instability in Anomalous-Dispersion Regime of Fiber

摘要：

We focus the effect of stimulated-Raman-scattering (SRS) on modulation instability (MI) in anomalous-dispersion regime of optical fiber from extended nonlinear Schr(O)inger equation. An expression of the gain of MI is given and the ranges and the growth of the gain spectrum are theoretically and numerically analyzed under considering SRS or neglecting SRS. The gain peak is also theoretically demonstrated. The effect of SRS on the frequency spectrum of MI is few when incident power is small. And incident power increases, the spectrum varies obviously, the range and the growth of the gain is lower if considering SRS than that of the gain if neglecting SRS. We also find that the maximum incident power will be limited by the fourth-order dispersion and will be enlarged by SRS to an extent.
