| 摘 要： | 首先介绍了利用掺铒光纤放大器（EDFA）快速计算的理论模型分析一般EDFA瞬态响应中存在的增益饱和引发的串扰现象。然后分析了两端加入布拉格光纤光栅的EDFA，表明这种改进后的EDFA可以有效地抑制增益饱和引发的串扰现象，使EDFA更加适合应用于WDM光通信系统，有关的数值计算结果和实验相符。

| Abstract: | A fast model of EDFA is introduced firstly. Using this model, the gain-induced crosstalk of EDFA is analyzed. Then the transient analysis of EDFA with Bragg gratings written on the fiber ends is implemented. The numerical results show that such a kind of EDFA can restrain the gain-induced crosstalk phenomenon effectively and make the EDFA suitable for WDM system use. The numerical results are consistent with the experiment results. |
