Researchers have designed electromechanically reconfigurable ultrathin optical elements that can be controlled and programmed on a pixel-by-pixel level. These versatile metasurfaces could offer a new chip-based way to achieve nanoscale control of light, which could lead to better optical displays, information encoding and digital light processing.
