小型化抗辐照EDFA研究

Study on miniaturized anti-irradiation EDFA

为了研制面向卫星激光通信的小型化抗辐照掺铒光纤放大器(EDFA),介绍了掺铒光纤(EDF)在辐照环境下的失效机理,研究了不同掺铒浓度EDF的辐照性能,对比了不同材料复合屏蔽结构的抗幅照性能,最终实现了一种尺寸为60 mm×60 mm×15 mm、输出功率超过23 dBm和在20 krad(SI)辐照剂量下输出功率波动幅度低于0.1 dB的高性能小型化抗辐照EDFA。

In order to develop a miniaturized anti-irradiation erbium-doped fiber amplifier(EDFA)for satellite laser communication,the failure mechanism of erbium-doped fiber(EDF)in the irradiation environment is introduced,the irradiation performance of different erbium-doped concentrations EDF is studied,and the anti-irradiation performance of different material composite shielding structures is compared.Finally,a high-performance miniaturized anti-irradiation EDFA with a size of 60 mm×60 mm×15 mm,an output power of more than 23 dBm and an output power fluctuation of less than 0.1 dB at 20 krad(SI)irradiation dose is realized.
