Unified analysis of four-photon mixing, modulational instability, and stimulated Raman scattering under various polarization conditions in fibers

Abstract

We present the analysis of parametric and Raman effects in the framework of a single approach. We discuss the transformation of gain spectra for Stokes and anti-Stokes waves under pump wavelength tuning from the region of positive group-velocity dispersion to the region of negative group-velocity dispersion for different types of phase-matching mechanism in a birefringent fiber.
