摘要
文章作者就分布式拉曼光纤放大器(DRFA)在各类传输光纤中应用时出现的四波混频(FWM)现象进行了理论分析和试验测试。从理论上分析了在大有效面积光纤(LEAF)中出现FWM新波长的频率,并得到了试验证明。在此基础上,提出了在LEAF中应用DRFA的设计原则,建议最后一个泵浦波长应该尽量远离零色散波长点。
The paper analyzes the Four Wave Mixing（FWM） phenomenon of distributed raman fiber amplifier on Leaf. We observed the FWM phenomenon in broadband distributed Raman fiber amplifier （DRFA）. This is one of the nonlinear effects which limits the performance of Raman amplified systems. We analyze the FWM effects for different fiber types. Finally we reduced the FWM influence successfully by choosing proper wavelengths in experiment.
