Detecting mid-infrared light by molecular frequency upconversion in dual-wavelength nanoantennas. Science 374 (6572), 1268-1271
Here, for the first time, we used the infrared absorption and Raman activity of molecular vibrations in plasmonic nanocavities to demonstrate frequency upconversion.
Energy-resolved plasmonic chemistry in individual nanoreactors. Nature Nanotechnology 16 (12), 1378-1385
We have demonstrated an energy-resolved plasmonic tool that can be used to initiate and simultaneously spectroscopically probe chemical and physical processes at the surface of plasmonic nanostructures.
Interfering plasmons in coupled nanoresonators to boost light localization and SERS. Nano Letters 21 (6), 2512-2518
Plasmon interference in these hybrid microresonator nanocavities produces surface-enhanced Raman scattering (SERS) signals many-fold larger than in the bare plasmonic constructs.
Controlling optically driven atomic migration using crystal-facet control in plasmonic nanocavities. ACS Nano 14 (8), 10562-10568
We report a robust and simple technique to exploit crystal facets and their atomic boundaries to prevent the hopping of atoms along and between facet planes.
Fibre-optic metadevice for all-optical signal modulation based on coherent absorption. Nature Communications 9 (1), 182
We show that integration of metamaterial and optical fibre technologies allows the use of coherently controlled absorption in a fully fiberized and packaged switching metadevice
Nanoscale Metafoils with enhanced mechano-optical properties for solar radiation isolation. ACS Applied Nano Materials 5 (11), 16164-16171
Here, we show nanoscale “metafoils” with plasmon resonances, allowing interplay with visible radiation while reflecting the unwanted infrared responsible for device heating, essential for satellite applications.
