Controlling the polarization and phase of high-order harmonics with a plasmonic metasurface

ORAL

Abstract

Metasurfaces have been utilized to enhance the emission of high-order harmonics of femtosecond infrared laser pulses, by enhancing the incident field, and to shape the emitted high harmonics in space. Here we show control of the polarization and phase of high harmonics with a plasmonic Pancharatnam–Berry phase metasurface. The latter generates circularly polarized deep-ultraviolet high harmonics, from a circularly polarized infrared driver, providing a simple path for achieving circular emission from patterned crystals. Our metasurface enhances the circularly polarized harmonics up to ∼43 times when compared to the unpatterned surface.
