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…
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…
Third-harmonic light polarization control in magnetically-resonant silicon metasurfaces
Andrea Tognazzi, Kirill I. Okhlopkov, Attilio Zilli +9
Nonlinear metasurfaces have become prominent tools for controlling and engineering light at the nanoscale. Usually, the polarization of the total generated third harmonic is studie…
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…
Enhanced nonlinear optical response of single metal-dielectric nanocavities resonating in the near-infrared
Nicolò Maccaferri, Attilio Zilli, Tommi Isoniemi +5
Harmonic generation mechanisms are of great interest in nanoscience and nanotechnology, since they allow generating visible light by using near-infrared radiation, which is particu…
Chiral Surface Waves for Enhanced Circular Dichroism
Giovanni Pellegrini, Marco Finazzi, Michele Celebrano +2
We present a novel chiral sensing platform that combines a one-dimensional photonic crystal design with a birefringent surface defect. The platform sustains simultaneous transverse…
