摘要
提出了由C波段和传统的 980nmLD两段级联抽运L波段信号的结构 ,C波段的功率和波长由掺铒光纤激光器控制。从实验和理论上分析了注入不同波长和功率的C波段对其增益的影响。设计的掺铒光纤放大器(EDFA)结构 ,在C波段波长为 15 2 5nm ,注入功率为 5mW时 ,功率为 - 2 0dBm ,波长为 15 80nm的信号增益提高了 7 7dB。
A structure of two-stage erbium-doped fiber amplifier (EDFA) pumped by C-band and 980 nm laser diode (LD) for gain enhancement of L-band signal was investigated via experiments and numerical calculation. C-band light was controlled by erbium-doped fiber laser. The influence of C-band power and wavelength on gain of L-band was analyzed principally. In the experiment, with an injection of 5 mW at 1525 nm, the gain enhancement of 7.7 dB for -20 dBm signal power at 1580 nm was achieved.
