Vector Photonics demos free space optical communication using a PCSEL for the first time outside of a lab

AI-summarised brief · reviewed before publication

Vector Photonics, a Scottish start-up, has successfully demonstrated free space optical communication using photonic crystal surface emitting lasers (PCSELs) outside of a lab for the first time. The technology, developed with Fraunhofer UK, enables secure, long-distance, fast communications. A 500m data transfer at 50 Mbps was achieved, exceeding system specs, with error rates below standard thresholds, marking a major step forward for commercial PCSEL applications.
