Outline

By embedding organic electro-optic polymer inside subwavelength gratings made of silicon or metal, we demonstrate electrically controllable active optical metasurfaces to realize normal-incident high-speed optical intensity/phase modulators. Through large-scale 2D-array integration, we enable high-speed manipulation of the wavefront of light at a speed faster than the conventional spatial light modulators by six orders or more. As an outcome of this project, we aim to create a novel area of applications that ultimately utilize both the temporal and spatial properties of light.
