摘　　要：针对磁流体在光纤领域的应用及其发展,本文综述了有关磁流体的成分组成、应用、特点和国内外的研究进展等。对磁流体的可调谐折射率、热透镜效应、光透射特性、双折射性、磁致色散特性等相关光学特性进行总结,并介绍了磁流体在光纤磁场传感器、可调谐磁流体光栅、可调谐光滤波器、光开关、光纤调制器、可调谐偏振光分束器等不同光器件中的应用,同时,分析了近年来国内外学者在光纤领域的研究进展。研究结果表明,虽然光纤磁场传感器凭借优良的性能,在航空航天、土木工程、石油化工、电力行业等领域具有重要作用,但随着光纤传感器的发展,光纤传感器应克服多参数交叉敏感性,其高灵敏度和微型化需要更为严格的封装技术,而且通过各种封装技术光纤传感器可以满足不同环境的应用要求。磁流体光特性的研究在光通信和传感技术等领域具有越来越重要的作用。For the application of magnetic fluid in the optical fiber field,this paper reviews the component composition,application,characteristics and the research progress at home and abroad.It summarize the related optical characteristics of tunable refractive index,thermal lens,optical transmission,birefringence and magnetic dispersion,introduces magnetic fluid in optical field sensor,adjustable magnetic fluid grille,optical switch,optical modulator,tunable polarization beam divider and other different optical devices,and analyzes the research progress of scholars at home and abroad in the field of optical fiber.The research results show that although the fiber magnetic field sensors play important roles in aerospace,civil engineering,petrochemical,and power industry,with the development of fiber sensors,they should overcome the cross sensitivity of multi-parameters,its high sensitivity and miniaturization need more stringent packaging technology,and the packaging of fiber sensors can meet the application requirements of different environments.The study of magneto-fluid optical properties plays an increasingly important role in fields such as optical communication and sensing technology.
