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…
Infrared up-conversion imaging in nonlinear metasurfaces
Rocio Camacho-Morales, Davide Rocco, Lei Xu +15
Infrared imaging is a crucial technique in a multitude of applications, including night vision, autonomous vehicles navigation, optical tomography, and food quality control. Conven…
