Abstract

Experimental results on all domestic-made erbium-doped fiber amplifiers (EDFAs) pumped by 1.47 μm laser diode are reported in this paper. Using mode-field matching technique, the fusion loss between standard single-mode fiber (MFD=9.125 μm) and erbium-doped fiber (MFD=3.88 μm) decreased to 0.2 dB. Gain characteristics of EDFAs are investigated and small-signal gain of 24 dB has been obtained.
