Abstract
Optical metasurfaces have shown an increasing promise to efficient nonlinear frequency conversion due to the presence of Mie-type resonances. Such enhanced nonlinear wave-mixing has opened an opportunity for frequency up-conversion of infrared images to visible in ultra-thin optical devices. Here we demonstrate GaAs metasurface infrared imaging with femtosecond time resolutions. Our results open new opportunities for the development of compact night-vision devices operating at room temperature and have multiple applications in defence and life sciences.
