| 摘 要： | 利用速率方程模型,对980nm泵浦带光隔离器的两段型掺铒光纤放大器(EDFA)的性能进行了研究,分析了增益、噪声系数、输出信号功率与泵浦光功率、输入信号光功率等参数之间的关系,结果表明小信号增益至少可提高3dB,噪声系数降低1.0dB,接近量子极限噪声系数。

| Abstract: | The rate equation model is setup for analyzing two-stage erbium-doped fiber amplifiers (EDFA) . The isolator within EDFA suppresses the backward propagating amplified spontaneous emission and improves the gain and noise characteristics as well as the output signal power characteristics. The results show that the small signal gain can be increased 3dB, the noise coefficient has been decreased 1.0dB, nearly to quantum level. |
