III-V Epi brings epitaxial manufacturing expertise to the University of Glasgow’s CTA programme.

28 September 2025

III-V Epi brings crucial, independent, epitaxial manufacturing expertise to the University of Glasgow’s Critical Technologies Accelerator (CTA) programme. The CTA supports joint academic and industrial collaborative projects for semiconductor, photonics and quantum technology development in Scotland; funded by the UK Government’s Innovation Accelerator levelling-up programme. The CTA’s purpose is to link the University of Glasgow’s worldclass, semiconductor laser development expertise, based at the James Watt Nanofabrication Centre (JWNC), with industrial partners, mitigating research costs. It also targets economic growth in Glasgow and prioritises support of a Scottish, sovereign supply chain. 

Calum McGregor, Director of III-V Epi, said, “III-V Epi is a business which provides fast turnaround, low and medium volume manufacture of III-V epitaxial structures, complete with testing and characterization support services. This is an essential part of bringing innovative photonics projects to market quickly and efficiently. Like the CTA, we are based in Glasgow, at the heart of Scotland’s sovereign, photonics supply chain.
“Many of the emerging markets targeted by the CTA, including computing, communications, space, fintech, healthcare, and defence, favour gallium arsenide (GaAs) material systems for manufacturing flexibility, where we have valuable know-how. However, we also work extensively with indium phosphide (InP), widely used in datacoms, telecoms, AI and HPC.”

The CTA has already delivered successful projects for secure cryptographic, financial transactions and Augmented Reality and Virtual Reality (VR).
