Plasmon-enhanced circular dichroism spectroscopy of chiral drug solutions
Matteo Venturi, Raju Adhikary, Ambaresh Sahoo +9
We investigate the potential of surface plasmon polaritons at noble metal interfaces for surface-enhanced chiroptical sensing of dilute chiral drug solutions. The high quality fact…
Meta-Optics with Lithium Niobate
Anna Fedotova, Luca Carletti, Attilio Zilli +8
The rapid development of metasurfaces - 2D ensembles of engineered nanostructures - is presently fostering a steady drive towards the miniaturization of many optical functionalitie…
All-optical Reconfiguration of Ultrafast Dichroism in Gold Metasurfaces
