Beam steering and dynamic focusing by coherent control of light with light on metasurfaces

Beam steering and dynamic focusing by coherent control of light with light on metasurfaces
We report continuous ‘coherently controlled’ tuning of the wavefront of light scattered by phase-gradient silicon metasurfaces, which enables optical-frequency beam steering and dynamic focusing without moving parts.

Abstract

We report continuous ‘coherently controlled’ tuning of the wavefront of light scattered by phase-gradient silicon metasurfaces, which enables optical-frequency beam steering and dynamic focusing without moving parts.
