【摘要】：根據(jù)磁光非線性光纖中導(dǎo)波光脈沖的四波混頻(FWM)耦合模方程,數(shù)值計(jì)算了施加不同磁場(chǎng)時(shí)相同偏振和接近正交偏振線偏光入射兩種情況下的FWM功率傳遞函數(shù)(PTF),并實(shí)驗(yàn)測(cè)試了相應(yīng)的再生光功率最大和最小兩種起始狀態(tài)下光纖磁光效應(yīng)對(duì)FWM PTF的影響,實(shí)驗(yàn)結(jié)果與理論曲線基本吻合。研究表明,對(duì)光纖施加適當(dāng)?shù)拇艌?chǎng),有助于提升再生器的消光比性能;在接近正交偏振線偏光入射時(shí),再生閑頻光功率隨磁場(chǎng)的變化最為敏感。
[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.
