| 摘 要： | 提出了一种基于光纤环形镜作为反射器的反射式L-波段掺铒光纤放大器(EDFA)结构。光纤环形镜不但可以反射后向放大自发辐射(ASE)作为二次抽运源，而且还可以反射信号，使信号得到二次放大。当抽运功率为115mW时。在1570～1605nm波长范围内，反射式L-波段掺铒光纤放大器的平坦小信号增益达到29．14dB，与前向抽运方式L-波段掺铒光纤放大器相比(保持平坦性不变)。增益提高了5．33dB。分别输入波长为1580nm和1600nm的信号，反射式L-波段掺铒光纤放大器的饱和输出功率为7．63和7．6dBm．与前向抽运方式L-波段掺铒光纤放大器相比分别提高了2．98和3dB。

| Abstract: | A novel reflection L-band erbium-doped fiber (EDF) amplifier is constructed based on fiber loop mirror (FLM), which reflects the backward ASE to the EDF as a secondary pumping source. And the signal can also be reflected into the EDF by the FLM so that it is amplified secondly. In the wavelength region from 1570 nm to 1605 nm, the small signal gain is 29.14 dB increasing by 5.33 dB compared to the forward end-pumped erbium-doped fiber amplifier (EDFA) when the pump power is 115 mW. The saturated output power is 7.63 and 7.6 dBm for 1580 nm and 1600 nm signal increasing 2.98 and 3 dB compared to the forward end-pumped EDFA, respectively. |
