Ultrasensitive hyperspectral imaging and biodetection enabled by dielectric metasurfaces

Volkan Cevher, Hatice Altug, Filiz Yesilköy, Andreas Tittl, Yasaman Jahani, Eduardo Romero Arvelo, Mingkai Liu

Metasurfaces based on resonant subwavelength photonic structures enable novel ways of wavefront control and light focusing, underpinning a new generation of flat-optics devices. Recently emerged all-dielectric asymmetric metasurfaces, composed of arrays of ...

All-dielectric Metasurfaces for Infrared Absorption Spectroscopy Applications

Hatice Altug, Filiz Yesilköy, Andreas Tittl, Aleksandrs Leitis, Mingkai Liu

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 ...

Angle-multiplexed all-dielectric metasurfaces for broadband molecular fingerprint retrieval

Hatice Altug, Andreas Tittl, Aleksandrs Leitis, Bang Hyun Lee, Mingkai Liu

Infrared spectroscopy resolves the structure of molecules by detecting their characteristic vibrational fingerprints. Subwavelength light confinement and nanophotonic enhancement have extended the scope of this technique for monolayer studies. However, cur ...
