All-dielectric Metasurfaces for Infrared Absorption Spectroscopy Applications

Leitis, Aleksandrs; Tittl, Andreas; Liu, Mingkai; Yesilkoy, Filiz; Choi, Duk-Yong; Neshev, Dragomir; Kivshar, Yuri; Altug, Hatice


We present a nanophotonic method capable of detecting mid-infrared molecular fingerprints without the need for spectrometry, frequency scanning, or moving mechanical parts. We leverage dielectric metasurfaces featuring ultra-sharp resonances each tuned to discrete frequencies, enabling us to sample molecular absorption signatures over the mid-IR spectral range.
