Polarization-controlled optical holography using flat optics.

Published in: Light, science & applications (2020)

Due to the large number of degrees of freedom offered by nanoscale scatterers, a single flat optic can project different images at different distances depending on the polarization of the light, opening up opportunities for optical encryption and augmented reality systems.
