This paper-thin chip turns invisible light into a steerable beam

Creating extremely small devices that can precisely guide and control light is a key challenge for many emerging technologies. Scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have now made an important advance by developing a metasurface that can convert invisible infrared light into visible light and direct it in specific directions without relying on any moving parts. Their findings are described in a new study published in the journal <...
