Technology Scotland recently caught up with our member, III-V Epi ,  for our Member Spotlight series. We  find out who III-V Epi are, what they do, and much more! Take a look below and get to know them.

What does your organisation do?

III-V Epi specialises in fast, low- to medium-volume manufacture of III-V epitaxial structures, utilising MBE (Molecular-Beam Epitaxy) and MOCVD (Metalorganic Chemical Vapour Deposition) processes. Customers define the epitaxy layers of their wafer structures to achieve specific parametric performance, with designs remaining their intellectual property. III-V Epi delivers value through its fabrication expertise and experience, ensuring design objectives are met accurately—often saving time and reducing costs by preventing specification errors. This distinctive value proposition is especially suited to markets and projects outside of high-volume consumer electronics, which currently dominate global, photonics industry production.

III-V Epi’s methods enable customers to quickly and efficiently launch innovative photonics projects, with III-V Epi’s compound semiconductor devices already advancing telecoms, datacoms, additive manufacturing, AI, LiDAR, and sensing sectors. The company specialises in materials systems such as arsenic, antimony, and phosphorous structures, including gallium arsenide (GaAs), noted for manufacturing versatility, and indium phosphide (InP), widely used in datacoms, telecoms, AI, and HPC.

Beyond wafer design, product development, and process optimisation, III-V Epi provides comprehensive test, metrology, and characterisation services like electrochemical capacitance-voltage (eCV), X-ray diffraction (XRD), photoluminescence (PL) spectroscopy, Hall measurements, and Secondary Ion Mass Spectrometry (SIMS).

Located in Glasgow, III-V Epi sits at the centre of Scotland’s robust, sovereign photonics supply chain.

What is your organisation’s biggest achievement?

III-V Epi’s most significant accomplishment, achieved within five years, is that over two-thirds of its revenue now derives from industrial projects with sustained supply demands. The remaining portion originates from start-up ventures and academic initiatives, which, while potentially less commercially lucrative, ensure the company remains at the forefront of III-V epitaxial structure design and development. This strategic balance enhances the organization’s expertise and knowledge across a range of sectors, driving progress in medicine, communications, quantum technology, defence, security, automotive, agriculture, and manufacturing.

III-V Epi is committed to ongoing development and innovation in its design, manufacturing, testing, and characterization services, thereby streamlining device production and accelerating new product introduction (NPI) for its clients.

Tell us something exciting about your organisation

III-V Epi will exhibit at SPIE Photonics West exhibition and conference in San Francisco, 20-22 January 2026. As the largest photonics event worldwide, it’s an ideal venue for showcasing III-V Epi’s wafer design, manufacturing, testing, and characterisation services.

Why did you join Technology Scotland?

The team at III-V Epi chose to join Technology Scotland to actively participate in the Scottish photonics technology ecosystem. This membership will provide III-V Epi with increased visibility in Scotland’s photonics sector and offer opportunities for political lobbying and influence at both Holyrood and Westminster. The staff at Technology Scotland possess qualifications, expertise, and experience in photonics, giving them a solid understanding of our business operations and the applications of our services.
