Overview
Deep tech University of Glasgow spin-out, Vector Photonics is a specialist semiconductor laser company developing patented Photonic Crystal Surface Emitting Laser (PCSEL) technology.
PCSELs combine high optical power, excellent beam quality, broad wavelength flexibility and low-cost, scalable manufacturing in a surface-emitting architecture, offering significant advantages over conventional edge-emitting lasers. As a fabless company, Vector Photonics leverages established commercial semiconductor foundries to enable rapid scaling and cost-effective production.
The technology has been demonstrated in real-world applications, including a free-space optical communications link across the River Clyde, highlighting its potential for next-generation communications. PCSELs are well positioned for emerging AI and hyperscale data centre applications, where efficient, high-performance optical interconnects are increasingly critical. Beyond communications, the technology offers opportunities in LiDAR, sensing and industrial processing.
Vector Photonics is supported by a highly experienced team with deep expertise in semiconductor lasers, photonics and commercialisation. The company has secured public and private investment and received multiple awards recognising both its technological innovation and commercial potential.
As it moves towards volume deployment, the company is focused on building commercial traction and strengthening engagement across the global photonics supply chain.
