Selective Light Transmission Could Advance Optical Computing

Facebook Twitter LinkedIn Email
CHAPEL HILL, N.C., July 19, 2018 — A new way to select and send light of a specific color over long distances has been applied to development of a nanoscale “light switch” for turning on and turning off the transmission of one color of light. The technique, which uses long silicon wires that are several hundred nanometers in diameter, could lead to a new platform for controlling light management when designing optical circuits. The Encoded Nanowire Growth and Appearance through VLS and Etching (ENGRAVE) technique (VLS = vapor-liquid-solid), developed by a team at the University of North Carolina at Chapel...Read full article
