摘要

我们提出了一种简单的矩形晶格微结构光纤(MOF)等离子体折射率(RI)传感器，用于分析物的测量，其RI范围为1.35至1.40。采用有限元法对该传感器的灵敏度进行了分析。仿真结果表明，该传感器的幅值灵敏度可达1200 RIU-1，波长灵敏度可达12000 nm/RIU，分辨率可达8.33 × 10-6 RIU。此外，在MOF结构外沉积金膜使得该传感器具有实际可行性，并使约束损耗非常低。由于这些优点，所提出的传感器可用于分析物的传感应用。

Low Loss Microstructure Optical Fiber Refractive Index Sensor based on Surface Plasmon Resonance

We propose a simple rectangular lattice microstructure optical fiber (MOF) based plasmonic refractive index (RI) sensor for analyte sensing having RI range from 1.35 to 1.40. Sensitivity analysis of the suggested RI sensor is done by finite element method (FEM). Simulation result shows that amplitude and wavelength sensitivity of the presented RI sensor can reach 1200 RIU-1 and 12,000 nm/RIU, respectively, while corresponding resolution is obtained of 8.33 × 10-6 RIU. In addition, deposition of gold film outside the MOF structure makes this sensor practically feasible as well as keeps the confinement loss very low. Due to these advantages, the suggested sensor can be used in analyte sensing application.
