“…In LSPR-PCF, metal is generally applied to the sensing area in the form of small balls or metal wires. Shengxi Jiao et al proposed an LSPR-PCF sensor with silver nanowires deposited in microchannels, and the detection advantages of LSPR were well illustrated by comparing the silver nanowires with the same standard silver thin layer [20]. D. Paul and R. Biswas proposed an LSPR-PCF sensor based on Au nanospheres to enhance the detection sensitivity and range [21].…”

To achieve high performance and wide range detection, we propose an ultra-wide range high sensitivity plasmonic fiber optic sensor with a gold (Au) nanowire group array, which has both propagating surface plasmon resonance (PSPR) and local surface plasmon resonance (LSPR) sensing characteristics. The PSPR, LSPR, and PSPR+LSPR are presented as Au thin layers, Au spheres (or Au nanowires), and Au nanowire group arrays, respectively, and their respective properties are analyzed from theoretical, simulated, and numerical aspects. When detection is performed, the presence of both evanescent wave and electric field forces in the Au nanowire group array combines to significantly improve the sensor’s detection capability. Detection simulation analysis was performed using COMSOL Multiphysics software. The range of refractive indices that can be detected is 1.08 to 1.37 in the optical band from 1210 nm to 2140 nm. In the detection range, the maximum sensitivity of the detected wavelength is 13,000 nm/RIU. Our proposed sensor has a broad range, high sensitivity, and low refractive index detection, and has good research value and application prospects.

“…Such an evanescent wave propagates along a metal surface through free oscillating electrons that interact with photons. The localized surface plasmon resonance (LSPR) behavior [6,7,8,9] is a free-electron oscillation that is usually confined to metal nanostructures. The essence of the LSPR phenomenon is that the incident light wave transfers into the surface plasmon resonance in the form of an evanescent wave.…”

This paper proposes a methane sensor based on localized surface plasmon resonance (LSPR) of a hexagonal periodic gold nanoring array. The effects of structural parameters on the extinction spectrum and refractive index (RI) sensitivity are analyzed to obtain optimal parameters. In particular, the RI sensitivity can reach 550.08 nm/RIU through improvement of the sensor structure, which is an increase of 17.4% over the original value. After coating a methane-sensitive membrane on the inner and outer surfaces of the gold rings, the methane concentration can be accurately measured with a gas sensitivity of −1.02 nm/%. The proposed method is also applicable to quantitative analyses of components concentration and qualitative analyses of gas composition.
