Abstract

We propose a new pumping method for optical fiber amplifiers at 1480nm and 980nm that is able to provide high gain and low noise-figure. The gain and noise figure obtained were 38.3dB and 5.5dB with an improvement of 3.8dB and 1.4dB, respectively, at 1550nm, for -30dBm input power when compared to its counter-pumped design. This design also delivers higher gain and lower noise figure when compared to the common bi-directional dual-pumped designs. A power conversion efficiency of 44.5% was achieved in this design.
