摘要

在掺铒光纤放大器中，增益和噪声系数与光纤长度密切相关。本文对双级l波段EDFA WDM网络的长度相关增益和噪声图分析进行了仿真研究。在1562nm波长处获得了42dB的高增益，总EDF (EDF- i 5m和EDF- ii 5m)长度为10m，总泵浦功率(980nm泵浦和1480nm泵浦)为270mW。整个波长范围(1561nm-1617nm)噪声系数低于4.7dB。获得了48%的功率转换效率和60%的量子转换效率。本文还研究了增益和噪声系数随温度和光纤长度的变化。本文所讨论的结构能够成功地实现l波段高增益和低噪声系数的放大。

Analysis of Length Dependent Gain and Noise Figure in a Dual Stage L-Band EDFA configuration

In an Erbium Doped Fiber Amplifier the gain and noise figure are strongly dependent on fiber length. This paper presents simulative studies on Length Dependent Gain and Noise Figure Analysis in a Dual Stage L-Band EDFA WDM Network. A high gain of 42dB was obtained at 1562nm wavelength with a total EDF (EDF-I 5m and EDF-II 5m) length of 10m and total pump power (980nm pump and 1480nm pump) of 270mW. Low noise figure of less than 4.7dB occurs in the entire wavelength range (1561nm-1617nm). A high Power Conversion Efficiency of 48% and Quantum Conversion Efficiency of 60% has been obtained. This paper also studies the variation of gain and noise figure with varying temperature and fiber length. The configuration discussed in this capable of successfully implemented for L-band amplification with high gain and low noise figure.
