Distributed hybrid-fiber Raman amplifiers with a section of nonlinear microstructured optical fiber.

A distributed hybrid-fiber Raman amplifier with a 25-km single-mode fiber and a section of nonlinear microstructured optical fiber (NMOF) is proposed and experimentally investigated in detail. Three pump schemes and span configurations, as well as two NMOF types with different parameters and length were considered. The influence of the NMOF presence on the performance of the amplifier was analyzed. © 2006 Wiley Periodicals, Inc.
