    Ultra-thin display technology shows dozens of images hidden in a single screen
    Schematic of a spin- and wavelength-multiplexed metahologram. This hologram encodes multiple holographic images using a single-cell metasurface, where distinct images appear on the same image plane based on the incident spin states and operating wavelengths.

    From smartphones and TVs to credit cards, technologies that manipulate light are deeply embedded in our daily lives, many of which are based on holography. However, conventional holographic technologies have faced limitations, particularly in displaying multiple images on a single screen and in maintaining high-resolution image quality.

    Through the Quantum Looking Glass

    September 13, 2022, Categories  Physics, Technology/Electronics

    Green laser light illuminates a metasurface that is a hundred times thinner than paper, that was fabricated at the Center for Integrated Nanotechnologies. CINT is jointly operated by Sandia and Los Alamos national laboratories for the Department of Energy Office of Science. (Photo by Craig Fritz) Click on the thumbnail for a high-resolution image.

    A thin device triggers one of quantum mechanics’ strangest and most useful phenomena. An ultrathin invention could make future computing, sensing and encryption technologies remarkably smaller and more powerful by helping scientists control a strange but useful phenomenon of quantum mechanics, according to new research recently published in the journal Science.

    Scientists at Sandia National Laboratories and the Max Planck Institute for the...
