Scalable Fabrication of Thermally Reconfigurable Ge Metasurfaces Using Stencil Lithography for Mid-Infrared Molecular Sensing
Shovasis Kumar Biswas, Samir Rosas, Wihan Adi +4
Mid-infrared (mid-IR) spectroscopy enables label-free molecular detection and is widely employed in biomedical, environmental, and chemical sensing; however, its broader deployment…
Wafer-Scale All-Dielectric quasi-BIC Metasurfaces: Bridging High-throughput Deep-UV Lithography with Nanophotonic Applications
Aidana Beisenova, Wihan Adi, Wenxin Wu +5
High quality-factor (Q) dielectric metasurfaces operating in the visible to near-infrared range usually require sub-200 nm features, limiting their fabrication to expensive, low-th…
Dynamically Tunable Membrane Metasurfaces for Infrared Spectroscopy
Furkan Kuruoglu, Samir Rosas, Jin-Woo Cho +4
Mid-infrared spectroscopy enables biochemical sensing by identifying vibrational molecular fingerprints, but it faces limitations in instrumentation portability and analytical sens…
Mass-manufactured Gradient Plasmonic Metasurfaces for Enhanced Mid-IR Spectrochemical Analysis of Complex Biofluids
Samir Rosas, Shovasis Kumar Biswas, Wihan Adi +4
Mid-infrared spectroscopy offers powerful label-free molecular analysis capabilities but faces significant challenges when analyzing complex biological samples. Here, we present a…
Enhanced biochemical sensing with high-Q transmission resonances in free-standing membrane metasurfaces
Samir Rosas, Wihan Adi, Aidana Beisenova +7
Optical metasurfaces provide novel solutions to label-free biochemical sensing by localizing light resonantly beyond the diffraction limit, thereby selectively enhancing light-matt…
Trapping light in air with membrane metasurfaces for vibrational strong coupling
Wihan Adi, Samir Rosas, Aidana Beisenova +4
Optical metasurfaces can manipulate electromagnetic waves in unprecedented ways at ultra-thin engineered interfaces. Specifically, in the mid-infrared (mid-IR) region, metasurfaces…
