摘要
文章介绍了掺铥光纤放大器(TDFA)和增益位移掺铥光纤放大器(GS-TDFA)的基本工作原理。分析了不同的泵浦波长选择。随后,作者提出了一种使用半导体激光器泵浦两级高掺杂掺铥光纤的增益位移放大器方案。采用此方案的光纤放大器在30nm工作带宽上光增益大于20dB,饱和输出功率大于17dBm,噪声指数为5.9~6.2dB。
In this paper, we first introduce the basic operating principle of Thulium-Doped Fiber Amplifier (TDFA) and Gain- Shifted TDFA (GS-TDFA) and analyze different pumping wavelength options. Then, we propose a dual-stage GS-TDFA scheme, in which high concentration doping TDF and laser diode pumps are used. The prototype fiber amplifier in this structure achieves optical gain greater than 20 dB, saturated output power higher than 17 dBm and NF in the range of 5.9--6.2 dB in 30 nm operating bandwidth.
