摘　　要：双向掺铒光纤放大器(Bi-EDFA)是空域有源光纤腔衰荡传感系统的关键器件,其增益特性和噪声特性直接影响传感系统的稳定性。设计了适用于空域有源光纤腔衰荡传感系统的低增益、低噪声的增益钳制Bi-EDFA,并应用Optisystem仿真软件对其进行优化。仿真结果表明:通过优化设计,可获得增益系数、噪声系数分别为15.35 dB、3.52 dB,且能保持增益钳制的Bi-EDFA。The bidirectional erbium-doped fiber amplifier(Bi-EDFA)is a key component of the spatial domain active fiber cavity ring-down sensing system,and its gain characteristics and noise characteristics directly affect the stability of the sensing system.A low-gain and low-noise gain-clamped Bi-EDFA suitable for spatial active fiber cavity ring-down sensing systems is designed and optimized by Optisystem simulation software.The simulation results show that by optimizing the design,a Bi-EDFA with gain coefficient and noise coefficient of 15.35 dB and 3.52 dB respectively can be obtained,and the gain can be clamped.
