Metasurface engineering for collective resonances, tailored emissivity, and enhanced photodetectors

Abstract

Efficiently confining light at the nanoscale within optical antennas facilitates its precise manipulation and enables the creation of nanostructures with innovative photonic functionalities. We present results of utilizing the iron pyrite antennas to precisely engineer the emissivity of mid-infrared thermal emitters. We also explore multipole Mie resonances within arrays of transition metal carbides and nitrides, specifically focusing on MXene materials. This engineering is achieved by strategically manipulating multipole resonance effects and non-radiative dissipation processes.
