摘要

研究人员提出了一种基于表面等离子体共振（SPR）的传感器，该传感器使用负曲率圆形侧抛光光子晶体光纤。使用有限元法分析了传感器的灵敏度。研究了结构参数的影响。该传感器在折射率 1.370-1.396 范围内的平均波长灵敏度 (WS) 为 7846 nm/RIU，在 1.330-1.370 范围内的平均波长灵敏度 (WS) 为 2350 nm/RIU，最大波长灵敏度 (WS) 为 46000 nm/RIU。在折射率和磁场双参数传感方面，同时获得的磁场灵敏度为 0.84 nm/mT。所提出的 SPR 传感器具有出色的灵敏度，适合折射率和磁场传感应用。

Dual-channel photonic crystal fiber dual-parameter sensor exploiting surface plasmon resonance

A surface plasmon resonance (SPR) based sensor using a negative curvature circular side-polished photonic crystal fiber was proposed. The sensor’s sensitivity was analyzed using the finite element method. The impact of structural parameters was investigated. The sensor exhibits an average wavelength sensitivity (WS) of 7846 nm/RIU in the refractive index range of 1.370–1.396 and 2350 nm/RIU in the range of 1.330–1.370, with maximum WS of 46000 nm/RIU. For refractive index and magnetic field dual-parameter sensing, the simultaneously obtained magnetic field sensitivity is 0.84 nm/mT. The proposed SPR sensor demonstrates remarkable sensitivity, making it suitable for refractive index and magnetic field sensing applications.
