We demonstrate numerically and experimentally enhanced efficiency and polarization control of nonlinear mixing via 3D all-dielectric periodic nanostructures. The 3D spatial periodicity allows diffractive interferences of SH light for the phase control, while the meta-atom geometry allows the excitation of Mie-modes for polarization control.

Abstract
We demonstrate numerically and experimentally enhanced efficiency and polarization control of nonlinear mixing via 3D all-dielectric periodic nanostructures. The 3D spatial periodicity allows diffractive interferences of SH light for the phase control, while the meta-atom geometry allows the excitation of Mie-modes for polarization control.File in questo prodotto:
