【摘要】：推导了磁光非线性光纤萨尼亚克结构的传输矩阵,可用于分析光纤的双折射、磁光效应和非线性相移,偏振控制器状态以及整个光纤环总损耗对萨尼亚克透射率的影响。实验研究了萨尼亚克结构磁光调制和非线性光控光开关功能。在0.0177T磁场作用下,磁光调制度可达17.05dB,理论分析与实验数据吻合。当时钟抽运控制信号的峰值功率为28.2dBm时,光控光开关消光比可达25.8dB,进一步施加磁场可使开关消光比提升0.7dB。光控光萨尼亚克结构的磁场响应在一定程度上可以借助偏振控制状态进行等效分析。
[Abstract]:The transmission matrix of the Sanjak structure of magneto-optic nonlinear fiber is derived, which can be used to analyze the effects of birefringence, magneto-optic effect and nonlinear phase shift, the state of polarization controller and the total loss of the whole fiber ring on the transmissivity of Sanjak. The functions of magneto-optic modulation and nonlinear optical-controlled optical switch with Sanjak structure are experimentally studied. Under the action of 0.0177T magnetic field, the magneto-optical modulation system can reach 17.05 dB, the theoretical analysis is in agreement with the experimental data. When the peak power of the clock pumped control signal is 28.2dBm, the extinction ratio of the optical switch can reach 25.8 dB, and the extinction ratio of the switch can be increased by 0.7 dB when the magnetic field is applied further. To some extent, the magnetic field response of the light controlled light saniak structure can be analyzed by means of polarization control state.
