摘要：

In this paper, the effect of gain control technique in double pass parallel hybrid fiber amplifier in terms of gain level as well as pump powers optimization are simulated using Optisystem and experimentally validated. An average gain level of 22.8 dB and overall gain variation of 3 dB within C and L band regions are achieved. The gain flatness bandwidth of 60 nm from 1530 to 1590 nm are obtained. A comparison with a single pass parallel hybrid fiber amplifier is presented. This comparison showed an average gain level of 38.5% higher than single pass-structure utilizing only 650 mW of Raman pump which is 18.7% lower.
