High-temperature superconducting photonic integrated circuits: controlling photoresponse of superconductor van der Waals plasmonic metasurfaces at optical telecommunication wavelengths

We report on a novel numerical modelling approach to exploit the optical properties of nanostructured metasurface arrays at the surface of high-temperature superconductors (HTS) BSCCO van der Waals. The optical response results in resonance wavelength from visible light to the infrared region between T=15K and 85K suggest that the high-temperature superconducting plasmonic photoresponse could be efficiently controlled by altering the thickness and width of BSCCO nanowire arrays on both quartz and sapphire substrates.
