Capturing free-space optical light for high-speed Wi-Fi – Phys.org

Visible and infrared light can carry more data than radio waves, but has always been confined to a hard-wired, fiber-optic cable. Working with Facebook’s Connectivity Lab, a Duke research team has now made a major advance toward the dream of ditching the fiber in fiber optics.
While working to create a free-space optical communication system for high-speed wireless internet, the researchers also show that speed and efficiency properties previously demonstrated on tiny, single-unit plasmonic antennas…
