Metasurface perfect absorbers for light control: beyond visible and infrared emitters
We review our recent studies about perfect absorbers by plasmonic and all-dielectric metasurface and its applications. We demonstrate refractory plasmonic thermal radiation emitters at mid-IR wavelength. In addition, we review photothermal control of light in silicon Huygens’ metasurface perfect absorbers based on degenerate critical coupling and its applications to all-optical switching of light as well as intensity modulation by quadrupole resonance.
