Abstract :
We propose and demonstrate a novel scheme to achieve low polarization dependent gain (PDG) forward-pumped Raman amplification via polarization sweeping at 10 GHz. This scheme employs the asymmetry of electro-optic coefficients of LiNbO/sub 3/ crystals to sweep the pump SOP at 10 GHz across the Poincare sphere.
