摘要: 为了实现高灵敏度液体折射率传感器的高效制备,采用飞秒激光直写技术,在光纤末端刻蚀出矩形凹槽,辅以光纤熔接方法,制备出一种基于光纤内双开口法布里-珀罗(F-P)干涉腔的折射率传感器。该传感器的液体折射率传感灵敏度达到1107.76nm/RIU。讨论了温度对该传感器性能的影响,温度串扰小于0.0025nm/℃;基于海水含盐浓度与折射率的线性关系,探讨了该传感器在海水含盐浓度传感测量方面的应用,灵敏度为0.171nm/(mgmL-1)。结果表明,基于光纤内双开口F-P干涉腔的折射率传感器具有干涉谱对比度高、线性响应良好、灵敏度高、不易受温度串扰、结构紧凑、制备简单高效等优点,在生物、医疗、化学、环境等领域中有着广泛的应用前景。

Abstract: In order to achieve a high sensitive fiber sensor for liquid refractive index (RI) measurement through a simple and efficient method, a Fabry-Prot interferometer (F-PI) cavity in fiber with double-openings was fabricated by femtosecond laser micromachining followed by fiber fusion. Firstly a rectangular groove was ablated at the end of fiber by femtosecond laser direct writing. Then the fiber end with the groove was spliced with another fiber end to form the F-PI cavity with double-openings. The responses of the fiber sensor based on the F-PI cavity with double-openings to the liquid RI and temperature were investigated. The experiment results show that the sensitivity of the sensor for RI measurement can achieve 1107.76nm/RIU, and the crosstalk by temperature is less than 0.0025nm/℃. The application of the sensor for seawater salinity measurement was also discussed and its sensitivity achieves 0.171nm/(mgmL-1). This liquid RI fiber sensor based on the F-PI cavity with double-openings can have great application in the fields of biology, medicine, chemistry and environment due to its advantages of high constrast of the reflection spectrum, linear response, high sensitivity, low crosstalk of temperature, small size and simple fabrication.
