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

Leitis, Aleksandrs; Tittl, Andreas; Liu, Mingkai; Lee, Bang Hyun; Gu, Man Bock; Kivshar, Yuri; Altug, Hatice


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, current approaches still require complex spectroscopic equipment or tunable light sources. Here, we introduce a novel metasurface-based method for detecting molecular absorption fingerprints over a broad spectrum, which combines the device-level...[Show more]
