Abstract

提出了一种少模光纤迈克尔孙干涉仪（MI）级联法布里-珀罗干涉仪（FPI）的游标增敏折射率传感器。少模光纤MI用作参考干涉仪，开放腔FPI作为传感干涉仪，解决了传统双FPI传感器的参考干涉仪制备复杂、可控性差的问题。仿真研究了单模-少模光纤错位量对少模光纤模式激发效率的影响，以及少模光纤长度对增敏倍数的影响。基于仿真优化参数制备了少模光纤MI-FPI传感器，并测试了其折射率响应特性，分析了增敏极限及限制因素。该传感器在1.3384~1.3412的折射率范围内的折射率灵敏度达到12466.956 nm/RIU（灵敏度单位），相对于无MI级联的单个FPI传感器提升了12.29倍，放大倍数可基于少模光纤长度灵活控制。该方法使传感器的增敏效果显著、增敏倍数可控、制备方法简单且光谱稳定性好，在折射率传感领域具有潜在的应用价值。

期刊介绍： Researching is owned by Chinese Laser Press (CLP), which is established by Shanghai Institute of Optics and Fine Mechanics and Chinese Optical Society in 2009. Nowadays, CLP publishes 11 journals and manages three online platforms. Journal publishing activities include both traditional and digital models, and the first journal can be traced back to 1964. The CLP Online Library includes the CLP journals and partnered ones in China, and provides literature and intelligence services for users. The product platform, named as OEShow, connects sellers and buyers of optoelectronics products. Researching (formerly known as The CLP Publishing) is featured with stable operation and leading technology, collects CLP journals and partnered optics and photonics journals, and provides readers an optical publishing platform with global influence. CLP is on the way of building a modern publishing group combining traditional business and digital publishing.
