Abstract :
In this paper we review recent experiments where well designed highly nonlinear fibers (HNLFs) give rise to flat gain over 115 nm is, also we discuss the feasibility of broadband two-pump optical parametric amplifiers (2P-FOPAs). It is believed that further improvements in designing and fabrication of HNLFs could result in 2P-OPAs with more than 200 nm. However, there is still one factor that we observed enhanced the gain ripple, and this is a phase mismatch introduced by the real part of the Raman susceptibility. Nevertheless, it was observed that the amount of gain ripple introduced by this effect varied from fiber to fiber.
