Abstract

In this letter, a refractive index (RI) sensor was developed and experimentally validated using an interferometric design that integrates single-mode fiber (SMF), no-core multimode fiber, and another segment of SMF. The single-mode–multimode–single-mode structure was employed as a filter and inserted into an erbium-doped fiber ring laser to enhance the sensor's detection accuracy. Experimental findings show that the sensor provides an outstanding linear response, with an RI sensitivity of 96.639 nm/RIU over a measurement range of 1.3468–1.4061, along with strong stability.

在掺铒光纤环形激光器中使用SMS光纤的折射率传感器

在本文中，我们开发了一种折射率（RI）传感器，并通过干涉设计进行了实验验证，该设计集成了单模光纤（SMF）、无芯多模光纤和另一段SMF。采用单模-多模-单模结构作为滤波器插入到掺铒光纤环形激光器中，以提高传感器的检测精度。实验结果表明，该传感器具有良好的线性响应，在1.3468 ~ 1.4061的测量范围内，RI灵敏度为96.639 nm/RIU，稳定性强。
