Abstract

We experimentally demonstrate a wideband double-pass discrete Raman amplifier using a gold-film. In this Raman amplifier (RA), by using a one-end gilded fiber as the broadband reflector, signals and multi-pump are simultaneously reflected to propagate through the gain fiber for a second time in the opposite direction of the input. An increase in net gain of more than 150% has been achieved compared with that in the typical co-pumped Raman amplifier. The noise and polarization dependent gain (PDG) characteristics of such a RA are also investigated.
