摘要
给出一种全保偏掺铒光纤放大器,为了提高放大器的泵浦效率、输出信噪比和输出功率,实验中对放大器结构和光纤参数进行优化.结果表明,该放大器的输出功率可达105 mW,输出信噪比达到40 dB以上,具有较佳的输出特性.
In this paper, a polarization - maintaining erbium - doped fiber amplifier ( PM - EDFA) was presented. Through optimizing the structure and EDF parameters in the EDFA we have improved the efficiency of the pump, the output of signal - noise ratio (SNR) and power . The experiments showed that the EDFA output reached 105mW, SNR was higher than 40dB.
