Nonlinear Metasurface Fresnel Zone Plates for Terahertz Generation and Manipulation
[Image: see text] We introduce a nanoengineered nonlinear metasurface based optical element that acts as an emitting Fresnel zone plate of terahertz (THz) waves. We show that the nonlinear zone plate generates broadband THz radiation and focuses each generated frequency on a different focal point al...
