Abstract
This research explores the design, analysis, and optimisation of a biosensor utilising a one-dimensional superconductor-dielectric photonic crystal structure (1D-SD-PC). To the best of our knowledge, a superconductor-dielectric 1D-PC distributed Bragg structure (DBS) is used for the first time in the design and analysis of a biosensor. Materials that are superconductor and dielectric are used to construct the bilayer stack. Air is used as a dielectric material, and YaBa2Cu3O7 is used as a superconductor layer. As the middle cavity layer of the SD structure, a bio-sample layer containing the sample being tested is added. The structural characteristics are optimally adjusted to maximise sensor efficiency. According to the observed results, the suggested structure has the highest RI sensitivity, measuring 65 nm/RIU and having 90.6% reflection with a Q factor of 8571. The suggested sensing device is appropriate for use in medical bio-sensing applications.
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.
