光纤放大器的调节方法

光纤放大器的调节方法本页仅作为文档封面，使用时可以删除This document is for reference only-rar21year.March光纤放大器的调节方法无线光通信是以激光作为信息载体，是一种不需要任何有线信道作为传输媒介的通信方式。

与微波通信相比，无线光通信所使用的激光频率高，方向性强(保密性好)，可用的频谱宽，无需申请频率使用许可;与光纤通信相比，无线光通信造价低，施工简便、迅速。

它结合了光纤通信和微波通信的优势，已成为一种新兴的宽带无线接人方式，受到了人们的广泛关注。

但是，恶劣的天气情况，会对无线光通信系统的传播信号产生衰耗作用。

空气中的散射粒子，会使光线在空间、时间和角度上产生不同程度的偏差。

大气中的粒子还可能吸收激光的能量，使信号的功率衰减，在无线光通信系统中光纤通信系统低损耗的传播路径已不复存在。

大气环境多变的客观性无法改变，要获得更好更快的传输效果，对在大气信道传输的光信号就提出了更高的要求，一般地，采用大功率的光信号可以得到更好的传输效果。

随着光纤放大器(EDFA)的迅速发展，稳定可靠的大功率光源将在各种应用中满足无线光通信的要求。

1 、EDFA的原理及结构掺铒光纤放大器(EDFA)具有增益高、噪声低、频带宽、输出功率高、连接损耗低和偏振不敏感等优点，直接对光信号进行放大，无需转换成电信号，能够保证光信号在最小失真情况下得到稳定的功率放大。

、 EDFA的原理在掺铒光纤中注入足够强的泵浦光，就可以将大部分处于基态的Er3+离子抽运到激发态，处于激发态的Er3+离子又迅速无辐射地转移到亚稳态。

由于 Er3+离子在亚稳态能级上寿命较长，因此很容易在亚稳态与基态之间形成粒子数反转。

当信号光子通过掺铒光纤时，与处于亚稳态的Er3+离子相互作用发生受激辐射效应，产生大量与自身完全相同的光子，这时通过掺铒光纤传输的信号光子迅速增多，产生信号放大作用。

Er3+离子处于亚稳态时，除了发生受激辐射和受激吸收以外，还要产生自发辐射(ASE)，它造成EDFA的噪声。
