Electrically-controlled optical metasurfaces

Light projection displays play an increasingly important role in our modern life. Core projection systems including liquid crystal displays and digital micromirror devices can impose spatial light modulation and actively shape light waves. Recently, the advent of metasurfaces has revolutionized the design concepts in display technologies, enabling a new family of optical elements with exceptional degrees of freedom. In this talk, we will present examples of electrically-controlled metasurfaces for dynamic holographic displays. We will also outline the possibility to achieve programmability and addressability of optical metasurface devices at the single pixel level.
