摘要

本文对掺铒光纤放大器（ＥＤＦＡ）的噪声特性进行了全面的分析。把光信号和ＥＤＦＡ中放大自发辐射（ＡＳＥ）产生的量子噪声，以及信号──ＡＳＥ拍频噪声和ＡＳＥ─ＡＳＥ拍频噪声一并加以考虑。通过数值模拟，给出了不同信号功率和泵浦功率下的ＥＤＦＡ噪声系数。这些结果对优化ＥＤＦＡ的工作参量及其工程制作具有一定的指导作用。

Abstract

A comprehensive analysis of noise figure of Erbium-doped fiber amplifier（EDFA）has been carried out by including signal shot noise

amplified spantaneous emission （ASE） shot noise

as well as signal-ASE beat noise and ASE-ASE beat noise. Through numerical simulation

we can obtain some useful results under different input singal power and pump power level.We believe that these results will be a major advantage in determining the EDFA’s operation condition and design.
