    Liquid Crystal Metalens Enables Electric Zoom

    Article obtained from Photonics RSS Feed.

    A metalens developed by researchers from Cornell University and Samsung Advanced Institute of Technology can be focused using voltage rather than by mechanically moving its components. The lens, a proof of concept, is the first of its kind, the researchers reported, and opens possibilities to compact varifocal lenses. Those lenses could be used in imaging applications that include satellites, telescopes, and microscopes.

    Researchers merged a metalens with liquid crystals to tailor the metalens’s local phase response. This allowed the researchers to vary the focus of the metalens in a controlled way by varying the voltage applied across the device.
    Conceptual rendering of an ultrathin, electrically tunable metalens developed…
