Plasmonic-cavity Modulator for the Mid-IR with a Semi-transparent and Nonlinear Heavily-doped Semiconductor Mirror
Tommaso Venanzi, Raffaella Polito, Andrea Rossetti +15
We present a free-space plasmonic modulator based on a single heavily-doped semiconductor layer. We investigate its ability to modulate both the linear and nonlinear response at mi…

Anomalous frequency scaling of acoustic phonon damping in nickel cavities fabricated by ps-laser delamination
Alba Viejo-RodrÃguez, Andrea Rossetti, Marco Gandolfi +9
Single-shot picosecond (ps) laser induced delamination allows for the direct generation of suspended membranes from a continuous metallic film, offering a promising platform for co…

Modulation of sub-optical cycle photocurrents in an ultrafast near-infrared scanning tunnelling microscope
Andrea Rossetti, Florian Pagnini, Majdi Assaid +4
Lightwave-driven scanning tunnelling microscopy (STM) at near-IR frequencies promises an unprecedented combination of atomic spatial resolution and temporal resolution approaching…
