Abstract
Surface plasmon resonance sensing, which is based on photonic crystal fiber sensing technology, has a broad spectrum of applications in the detection of pharmaceuticals, environmental pollution, and food safety. This investigation proposes a photonic crystal fiber optic sensor with two cores and two holes to address the issue of limited sensor sensitivity. The high sensitivity of the sensor is optimized by the dual-channel design, which minimizes energy loss and maximizes the coupling efficacy in SPP mode by increasing the contact area of the measured liquid. Concurrently, the plasma resonance process generates an increased amount of energy due to the dual-core architecture. Simulation results show that the sensor has a maximum wavelength sensitivity of 21,500 nm/RIU and a maximum theoretical resolution as high as 4.878 × 10−7 RIU in the refractive index detection range of 1.33–1.43 and thus is expected to be applied in the field of hematology detection.
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.
