Abstrakt: In this paper, a new wideband double-pass hybrid fiber amplifier utilizing L-shape and a second-order Raman pumping scheme (DP-L-shape-HFASO) is implemented and investigated via OptiSystem software. The combination of the Raman second-order pumping scheme and the L-shape configuration provides a new HFA with efficient and outstanding performance in many aspects. The results show the proposed HFA provided a wide flat bandwidth of 80 nm extended over the short, conventional, and long band (S+C+L) ranging from 1515 to 1595 nm due to use the second-order pumping scheme. In addition, a high average gain (Gav.) of 25.64 dB and a proper average noise figure (NFav.) of about 7 dB are achieved through the use of the L-shape configuration. Finally, the optimal Raman pump power was reduced by 37.5% due to a double-pass configuration as compared with the single pass design, thereby improving the pump conversion efficiency.
