Vector Photonics

Vector Photonics develops Photonic Crystal Surface-Emitting Lasers (PCSELs), a breakthrough semiconductor laser technology born from 30 years of research at the University of Glasgow. PCSELs combine high power, versatility, and lower manufacturing costs compared to traditional lasers, with a unique surface-emitting design that enables easy integration into everyday electronics and industrial equipment. The technology targets the fastest-growing laser markets including data communications, additive manufacturing (metal and plastic 3D printing), LiDAR, and optical sensing. PCSELs are particularly advantageous for Free Space Optical Communication (FSOC) systems, offering narrow, high-brightness beams with excellent beam quality and low divergence for terrestrial and space-based applications. The company leverages existing semiconductor manufacturing processes and maintains a strong patent portfolio. Founded in 2020 and headquartered in Glasgow, United Kingdom, the company has raised approximately $7.3 million at the Series A stage, backed by government funding and private investment.
