Temperature-insensitive magnetic-field measurement using all-fiber Sagnac interferometers∗
摘要
Abstract
Magnetic field and temperature dependence of Sagnac interferometers consisting of birefringent magneto-optic fibers is inves-tigated. 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/◦C), 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.关键词
