Metasurfaces are planar optical elements composed of nanostructured arrays that enable arbitrary control over the wavefront, polarization, and other properties of incident light. While most demonstrations to date have focused on passive devices such as lenses and polarization beam splitters, incorporating reconfigurable mechanisms enables active functionality and dynamic modulation. These so-called active metasurfaces have attracted significant attention due to their ability to achieve spatiotemporal control of light. Among various approaches, electro-optic active metasurfaces based on organic electro-optic (OEO) materials integrated with nanostructured resonators are particularly promising, as they enable high-speed modulation (> MHz). In this talk, we present silicon-organic hybrid active metasurfaces that operate at high speed and low voltage.
