S型光纤锥的研究进展

Research Progress on S Fiber Taper

随着新型微加工工艺的发展,传统的锥型光纤发展派生出数千种不同的微结构光纤.其中,S型光纤锥由于其体积小、质量轻、抗电磁干扰以及可以直接嵌入结构化系统的灵活性得到了迅猛地发展.随着对S型光纤锥研究的深入,基于S锥的各种结构和功能的光纤传感器不断地被提出,用于测量温度、应变、折射率、湿度和磁场等,不仅丰富了光纤传感器的种类,更加深了人们对传感机理的认识.本文全面回顾了S型光纤锥的研究进展,包括传感原理、制备方法、各种传感结构组合以及传感应用等,并对其发展进行了展望.

With the development of new micromachining processes,the traditional tapered fiber has derived thousands of different microstructured fibers.Among them,S-type fiber taper has been rapidly developed due to its small size,light weight,anti-electromagnetic interference and flexibility to be directly embedded in the structured system.With the intensive study on S-type fiber tapers,fiber optic sensors based on various structures and functions of S-taper have been continuously proposed for measuring temperature,strain,refractive index,humidity and magnetic field,etc.,which enriches the types of fiber optic sensors and has deepened people's understanding of the sensing mechanism.This paper comprehensively reviews the research progress of S-type fiber tapers,including sensing principle,preparation method,various sensing structure combinations and sensing applications,and prospects for its development.
