Gain Spectra of Raman Scattering and Parametric Amplification in Birefringence Dispersion Shifted Fiber
Taking account of the coupling differential equations under the effect of Stokes and anti-Stokes for the pump wave linearly polarized and aligned with the
x
-axis direction
the gain coefficient for the Stokes and anti-Stokes have been derived from simultaneously act of stimulated Raman scattering and parametric amplification in the same
x
polarization. The Lorenz model of parallel gain coefficient is introduced in this equation. The correlation between the gain spectrum and correlative parameter studied in dispersion-shifted fiber. The conclusion shows that gain spectrum is dissymmetrical with the Stokes and anti-Stokes wave and has no relation with third-order dispersion. At the same time
the ratio of Stokes and anti-Stokes |
