Vector Photonics demos free space optical communication using a PCSEL for the first time outside of a lab
What happened
Vector Photonics demonstrated free-space optical communication using its Photonic Crystal Surface Emitting Lasers (PCSELs) over 500 meters at 50 Mbps. This field test, conducted with Fraunhofer UK, advances the technology's readiness level from TRL 4/5 to 6/7. Neutral: This is a long-term R&D milestone with no immediate impact on component supply, pricing, or trading decisions.
