  • 研究了双折射磁光光纤萨格纳克 (Sagnac) 干涉仪透射谱的磁场和温度敏感性. 实验表明, 干涉仪透射谱会随着温度的增加向短波长移动 (温度系数为-0.435 nm/℃), 其波长依赖性则随着磁场的增加而降低. 据此, 通过调节干涉仪内偏振控制器状态实现了温度不敏感的磁场测量, 磁场系数为189 mW/T2, 实验结果与理论分析一致.
    Magnetic field and temperature dependence of Sagnac interferometers consisting of birefringent magneto-optic fibers is investigated. Experimental results show that the transmission spectrum of the all-fiber Sagnac interferometer moves towards the shorter wavelength side with the increase in temperature (temperature coefficient -0.435 nm/℃), and the transmissivity becomes wavelength- insensitive for a larger magnetic induction. And then, the temperature-insensitive magnetic field measurement is achieved by adjusting the polarization controller within the interferometer, and the magnetic field coefficient is 189 mW/T2 in the experiment, which is in agreement with the theoretical results.
