Generation of spatiotemporally tailored terahertz wavepackets by nonlinear metasurfaces

Abstract

While the terahertz range has become increasingly important for a wide range of applications, efficient sources with bespoke output characteristics are still lacking. Here, Keren-Zur et al. show that engineering of a metasurface’s individual elements allows control of the spatiotemporal properties of the emitted terahertz radiation.
