Highly Sensitive Two-Parameter Anti-resonant Fiber (ARF) Sensor Based on Surface Plasmon Resonance in the Terahertz Band
A two-parameter anti-resonant fiber (ARF) sensor based on the principle of surface plasmon resonance (SPR) is designed to detect refractive index (RI) and temperature simultaneously. Graphene is coated on the externally cut negative curvature tube as the plasmonic medium to excite terahertz SPR for detecting the RI of the external liquid. In addition, polydimethylsiloxane (PDMS) is filled in the graphene-coated tube to sense the temperature of the liquid. The properties of the ARF-SPR sensor are analyzed by the finite element method. The maximum wavelength sensitivity and amplitude sensitivity of 13,888.9 µm/RIU and 87.40 RIU−1 respectively are observed at the second resonance peak for RIs between 1.3 and 1.36, and the minimum resolution is 7.2 × 10−9 RIU−1. In the temperature range of 26.85 to 76.85 °C, the first resonance peak is insensitive to the temperature, and the maximum temperature sensitivity and amplitude sensitivity of the second resonance peak are 8.4 µm/°C and 0.058 °C−1, respectively, with a resolution on the order of 10−5. This special design, boasting a simple structure, overcomes the limitations of single-parameter measurements and solves the problems of two-parameter cross-sensitivity while offering excellent sensing performance.
期刊介绍:
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
