摘要

本文采用非对称非线性光环路反射镜(NOLM)对掺铒光纤放大器(EDFA)降噪的最佳分裂比进行了分析。为了测量NOLM的降噪效果，我们将NOLM输出的噪声功率与作为参考电平的EDFA输出的噪声功率进行比较。这12 dB的降噪是实验中使用非对称NOLM实现的最佳结果。结论是，所示的设置对于脉冲持续时间大于1.3 ps的商用光通信系统是有吸引力的。

12 dB of noise reduction by a NOLM based all optical all passive regenerator

In this paper, an asymmetric nonlinear optical loop mirrors (NOLM) was used to analyse optimum splitting ratio for erbium doped optical fibre amplifier (EDFA) noise reduction. To measure the noise reduction of the NOLM, we compare the noise power at the NOLM output with the noise power at the EDFA output, acting as a reference level. This 12 dB of noise reduction is the best result experimentally achieved with an asymmetric NOLM. It is concluded that the setup shown becomes attractive for commercial optical telecommunication systems with pulse durations longer than 1.3 ps.
