Abstract

Using a theoretical model, we investigate the impact due to Raman scattering on frequency conversion obtained via Bragg scattering four-wave mixing in optical fibers. We predict the second order correlation functions and show that by using a specific polarization configuration of the pumps and signal it is possible to significantly mitigate the impact of Raman scattering by reducing the second order correlation function by at least a factor of two.
