Electrically switchable nanoantennas could enable holographic video technology

Video conferencing played a key role during the COVID-19 pandemic and is set to dominate many meetings in the future. To realize the true feeling of a face-to-face dialog, three dimensional video is required and yet the holographic technology is still missing. Researchers at the University of Stuttgart in Germany have now introduced a completely new approach to realize such dynamic holographic displays, based on electrically switchable plasmonic nanoantennas made from conductive metallic polymers. This key element provides the missing technology to enable holographic displays at video rate, which would enable virtual conferences with a "real-life" feeling. The paper detailing this work has been published in the journal Science on 29 October 2021.
