Origin of optical nonlinearity in plasmonic semiconductor nanostructures
Andrea Rossetti, Huatian Hu, Tommaso Venanzi +15
The development of nanoscale nonlinear elements in photonic integrated circuits is hindered by the physical limits to the nonlinear optical response of dielectrics, which requires…
All-optical free-space routing of upconverted light by metasurfaces via nonlinear interferometry
Agostino Di Francescantonio, Attilio Zilli, Davide Rocco +9
All-optical modulation yields the promise of high-speed information processing. In this frame, metasurfaces are rapidly gaining traction as ultrathin multifunctional platforms for…
Modelling photothermal induced resonance microscopy: the role of interface thermal resistances
Francesco Rusconi, Marco Finazzi, John M. Stormonth-Darling +6
Infrared (IR) nanospectroscopy by photothermal induced resonance (PTIR) is a novel experimental technique that combines the nanoscale resolution granted by atomic force microscopy…
Tunable broadband light emission from graphene
Lavinia Ghirardini, Eva A. A. Pogna, Giancarlo Soavi +12
Graphene is an ideal material for integrated nonlinear optics thanks to its strong light-matter interaction and large nonlinear optical susceptibility. Graphene has been used in op…
Spin-orbitronics at a topological insulator-semiconductor interface
T. Guillet, C. Zucchetti, A. Marchionni +9
Topological insulators (TIs) hold great promises for new spin-related phenomena and applications thanks to the spin texture of their surface states. However, a versatile platform a…
Tip-Enhanced Infrared Difference-Nanospectroscopy of the Proton Pump Activity of Bacteriorhodopsin in Single Purple Membrane Patches
Valeria Giliberti, Raffaella Polito, Eglof Ritter +11
Photosensitive proteins embedded in the cell membrane (about 5 nm thickness) act as photoactivated proton pumps, ion gates, enzymes, or more generally, as initiators of stimuli for…
