Near-infrared polarimetric imaging with nonlinear flat-optics
Evgenii Menshikov, Marco A. López Sánchez, Paolo Franceschini +4
A compact and broadband polarimetric imaging platform is presented, based on second-harmonic generation (SHG) in nonlinear flat-optics. The system employs periodic all-dielectric A…
Light structuring via nonlinear total angular momentum addition with flat optics
Evgenii Menshikov, Paolo Franceschini, Kristina Frizyuk +7
Shaping the structure of light with flat optical devices has driven significant advancements in our fundamental understanding of light and light-matter interactions, and enabled a…
Interface second harmonic generation enhancement in hetero-bilayer van der Waals nanoantennas
Andrea Tognazzi, Paolo Franceschini, Jonas Biechteler +5
Layered van der Waals (vdW) materials have emerged as a promising platform for nanophotonics due to large refractive indexes and giant optical anisotropy. Unlike conventional diele…
Copper-based disordered plasmonic system with dense nanoisland morphology
Tlek Tapani, Roman Krahne, Vincenzo Caligiuri +14
Dry synthesis is a highly versatile method for the fabrication of nanoporous metal films, since it enables easy and reproducible deposition of single or multi-layer(s) of nanostruc…
Near-unity third-harmonic circular dichroism driven by quasi-BIC in asymmetric silicon metasurfaces
Marco Gandolfi, Andrea Tognazzi, Davide Rocco +2
We use numerical simulations to demonstrate third-harmonic generation with near-unity nonlinear circular dichroism (CD) and high conversion efficiency () i…
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…
Tuning the Ultrafast Response of Fano Resonances in Halide Perovskite Nanoparticles
Paolo Franceschini, Luca Carletti, Anatoly P. Pushkarev +12
The full control of the fundamental photophysics of nanosystems at frequencies as high as few THz is key for tunable and ultrafast nano-photonic devices and metamaterials. Here we…
