摘要
为了实现高灵敏的表面等离子体共振(SPR)折射率传感, 提出一种基于大纤芯的单芯光子晶体光纤SPR传感结构, 采用全矢量有限元方法对其传感特性进行了数值仿真和分析。结果表明, 该结构具有比较宽的折射率传感范围(1.36~1.55), 同时具有较高的传感灵敏度, 平均传感灵敏度达12139nm/RIU; 在折射率1.36~1.42区域, 线性传感灵敏度为5646.4nm/RIU, 线性度为0.9317; 而在折射率1.42~1.57区域, 传感灵敏度达到15326.8nm/RIU, 线性度为0.98738, 传感特性出现明显的线性分段情况。该研究结果为实现高灵敏的光子晶体光纤SPR传感器提供了重要的理论依据。
Abstract
In order to detect the refractive index of surface plasmon resonance (SPR) with high sensitivity, a SPR sensing structure based on single core photonic crystal fiber with large core was proposed. The full vector finite element method was used to simulate and analyze its sensing characteristics. The results show that the structure has a wide range of refractive index sensing range (1.36~1.55). At the same time, the structure has high sensing sensitivity and the average sensitivity is 12139nm/RIU. With refractive index of 1.36~1.42, the linear sensor sensitivity is 5646.4nm/RIU and linearity is 0.9317. With refractive index of 1.42~1.57, the linear sensor sensitivity is 15326.8nm/RIU and linearity is 0.98738. Sensing characteristics appear in obvious linear subsections. The results provide an important theoretical basis for the realization of high sensitive photonic crystal fiber SPR sensors.
