In this paper the gain characteristics of two-pump fiber optical parametric amplifiers (FOPA) with two-section highly nonlinear fibers are analyzed numerically and the parameters of the fibers are optimized to reach broad and flat gain spectra using genetic algorithm. Different from the previous met

A broadband two-pump optical parametric amplifier with ultra-flat gain spectra is proposed in a single-section highly nonlinear fiber. By elaborately setting the dispersions and pump wavelength space, a gain over 250 nm with 0.02-dB uniformity is obtained. The pump polarizations and fiber length can
## Abstract A distributed hybridβfiber Raman amplifier with a 25βkm singleβmode 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 parameter
