【摘要】：根据磁光非线性光纤中导波光脉冲的四波混频(FWM)耦合模方程,数值计算了施加不同磁场时相同偏振和接近正交偏振线偏光入射两种情况下的FWM功率传递函数(PTF),并实验测试了相应的再生光功率最大和最小两种起始状态下光纤磁光效应对FWM PTF的影响,实验结果与理论曲线基本吻合。研究表明,对光纤施加适当的磁场,有助于提升再生器的消光比性能;在接近正交偏振线偏光入射时,再生闲频光功率随磁场的变化最为敏感。
[Abstract]:According to the FWM coupling mode equation of guided wave optical pulse in magneto-optic nonlinear fiber. The FWM power transfer function (PTF) is numerically calculated under the conditions of the same polarization and near-orthogonal polarization linear polarized light incidence under different magnetic fields. The effect of the optical fiber magnetic light efficiency on FWM PTF under the two initial states of maximum and minimum regenerated optical power is tested experimentally. The experimental results are in good agreement with the theoretical curves and the results show that the experimental results are in good agreement with the theoretical curves. Applying a proper magnetic field to the fiber will help to improve the extinction ratio of the regenerator. The power of regenerated idler light is most sensitive to the magnetic field when it is close to the incidence of orthogonal polarization line polarized light.
