| 摘 要： | 本文建立了考虑交叉相位调制效应（XPM）的光放大模型,得到了（XPM）效应对小信号增益系数的影响,分析得到:掺铒光纤放大器（EDFA）中XPM引起的强度起伏和非线性系数、输入的泵浦功率以及放大器长度有关。仿真结果证明:EDFA中XPM效应的影响不能忽略,并且当γ≥0.01/W·m时,级联EDFA中第一个EDFA产生的XPM效应的影响也是不能忽略的。

| Abstract: | The amplifier model with XPM effect is given. The XPM has an effec on the small-signal gain. The deviation caused by XPM effect in EDFA is stronger with the increasing of nonlinear coefficient, pump power and amplifier length. Simulation results prove: to neglect the XPM originating in the EDFA is inaccurate. This is particularly true when its higher coefficient of nonlinearity is taken into account, even in r >0.01/W.m, XPM in the first EDFA of a cascade EDFA can't be negnected. |
