1.47 μm LD泵浦掺铒光纤放大器的实验研究
Experimental study of erbium-doped fiber amplifier pumped by 1.47 μm laser diode
摘要
本文报道了采用国产器件进行的1.47 μm激光二极管(LD)泵浦的掺铒光纤放大器的实验结果。采用模场匹配技术使标准单模光纤(MFD=9.125 μm)与掺铒光纤(MFD=3.88 μm)之间的熔接损耗降至0.2 dB。研究了放大器的增益特性,获得了24 dB的小信号增益。
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.
