摘要/Abstract

摘要： 本文基于100 m长自研高锗掺铋硅基光纤实现了1 650~1 750 nm的U波段宽带放大，并在1 720 nm处获得了28.34 dB的最高增益。同时，通过实验和数值模拟系统地研究了泵浦配置对掺铋光纤放大器放大性能的影响。模拟与实验结果表明：在低泵浦功率下双向泵浦更有利于获得高增益和低噪声指数。此外，前向泵浦下的增益受输入信号功率的影响较大，双向泵浦下次之，后向泵浦下最为稳定。该研究可为U波段掺铋光纤放大器的设计优化和应用提供参考。

Abstract: Based on a 100 m long home-fabricated bismuth-doped silica fiber with high germanium content, the U-band broadband amplification of 1 650~1 750 nm was achieved with a maximum gain of 28.34 dB at 1 720 nm. At the same time, the influence of different pump schemes on the amplification performance of bismuth-doped fiber amplifier was systematically studied through both experiments and numerical simulations. Results show that bidirectional pumping is more conducive for achieving high gain and low noise figure at low pump power. Furthermore, the gain is greatly affected by the input signal power under forward pumping, followed by bidirectional pumping, and is most stable under backward pumping. This study can provide a reference for the design optimization and application of U-band bismuth-doped fiber amplifiers.

Key words: bismuth-doped fiber, fiber amplifier, U-band amplification
