摘要

提出并演示了一种折射率传感器。传感器头是通过在两个单模光纤段(SMS)之间拼接一段多模光纤制成的。将SMS结构作为滤波器插入铒光纤环中产生激光，提高了传感器的检测精度。该传感器提供了极好的线性响应。检测灵敏度为84.489 nm/RIU，测量范围为1.345 ~ 1.386。

Optical fiber laser sensor for refractive index measurement

A refractive index (RI) sensor was proposed and demonstrated. The sensor head was manufactured by splicing a section of multimode fiber between two single-mode fiber segments (SMS). The SMS structure was used as a filter and inserted into an Erbium fiber ring to generate laser, which can improved the detection accuracy of the sensor. The sensor provides an excellent linear response. RI sensitivity of 84.489 nm/RIU has been achieved and the measurement range is from 1.345 to 1.386.
