Raman Scattering and Parametric Amplification in Single-mode Birefringence Dispersion-decreasing Fiber
According to the coupling differential equations of the Stokes and anti-Stokes
the pump wave is linearly polarized and aligned with the
x
-axis direction. The gain coefficients have been reduced for the Stokes and anti-Stokes which simultaneously act of stimulated Raman scattering and parametric amplification in the same
x
polarization. The gain changes with mismatch

and normalized distance

in normal dispersion regime and anomalous dispersion regime. The gain will arise a peak and then with the
k

0. At the same time the feature about energy ratio of Stokes and anti-Stokes
