Nonvolatile Tunable Integrated Mid-Infrared GST-SiC Metasurfaces

摘要

We demonstrate an integrated mid-infrared 3C-SİC metasurface with relatively sharp transmission peaks associated with phonon-mediated magnetic polariton resonance. We further show the possibility of developing reconfigurable metasurfaces using such architectures by integrating a thin layer of phase-change material, Ge₂Sb₂Te₅, on top of the SiC layer.
