Abstract
A wideband double-pass discrete Raman amplifier with high gain efficiency and improved gain polarization dependence is reported. In this Raman amplifier, by using a one-end gilded fiber as the broadband reflector, both signals and pumps are reflected to propagate through the gain fiber in the opposite direction of the input. An increase in net gain and an improved polarization dependence of Raman gain have been achieved compared with that in a typical co-pumped Raman amplifier. The advantages of this proposed new configuration have been studied experimentally.
