Dynamically reconfigurable metasurfaces promise compact and lightweight spatial light modulation for many applications, including LiDAR, AR/VR, and LiFi systems. Here, we present a metasurface with full, electrically-driven independent control of its constituent nanoantennas, full phase tunability, and high tuning efficiency. Our metasurface consists of high quality factor Si nanoantenna bars atop lithium niobate. Free-space light couples to guided modes within each nanobar via subtle geometric…

Gate-Tunable Conducting Oxide Metasurfaces.
In principle, electrically gated phase and amplitude control allows for electrical addressability of individual metasurface elements and opens the path to applications in ultrathin optical components for imaging and sensing technologies, such as reconfigurable beam steering devices, dynamic holograms, tunable ultrathins, nanoprojectors, and nanoscale spatial light modulators.
Wavefront shaping and modulation with resonant electro-optic phase gradient metasurfaces
Phase gradient metasurfaces have revolutionized modern optical components by significantly reducing the path length of bulk optics while maintaining high performance. However, their geometric design
High quality factor phase gradient metasurfaces
By including subtle structural perturbations in individual metasurface elements, resonances are created that weakly couple free-space light into otherwise bound and spatially localized modes in subwavelength-thick phase gradient metAsurfaces.
Dynamic beam steering with all-dielectric electro-optic III–V multiple-quantum-well metasurfaces
This work reports an all-dielectric active metasurface based on electro-optically tunable III–V multiple-quantum-wells patterned into subwavelength elements that each supports a hybrid Mie-guided mode resonance, and demonstrates beam steering by applying an electrical bias to each element to actively change the metAsurface period.
Electro-Optically Tunable Multifunctional Metasurfaces.
This work demonstrates a reconfigurable metasurface that is multifunctional, i.e., notionally capable of providing diverse optical functions in the telecommunication wavelength regime, using a single compact, lightweight, electronically programmable array with no moving parts.
Phase-only transmissive spatial light modulator based on tunable dielectric metasurface
A concept of tunable dielectric metasurfaces modulated by liquid crystal is proposed, which can provide abrupt phase change, thus enabling pixel-size miniaturization, and is presented, configured to generate active beam steering with >35% efficiency and a large beam deflection angle.
Temporal color mixing and dynamic beam shaping with silicon metasurfaces
This work can realize metasurfaces with fast (>105 hertz), electrically tunable pixels that offer complete (0- to 2π) phase control and large amplitude modulation of scattered waves through the microelectromechanical movement of silicon antenna arrays created in standard silicon-on-insulator technology.
Dynamic focusing with high-quality-factor metalenses.
This work designs sub-micron-thick, ultrahigh quality factor (high-Q) metalenses that enable dynamic modulation of the focal length and intensity and shows how multiple high-Q resonances can be embedded in the lens response through judicious placement of the perturbations.
