Cnuic raises £2.2m seed to commercialise reconfigurable light-based photolithography for photonic chips
This article covers Cnuic, an Edinburgh-based photonic chip manufacturing tech startup, which has raised £2.2m in a seed funding round to commercialise a working prototype of a photolithography device that enables rapid, reconfigurable production of photonic chips. The funding is intended to help move photonic chip manufacturing from laboratory demonstration towards higher-volume production, with potential implications for data centres, AI training and other light-based systems.
Cnuic, an Edinburgh-based photonic chip manufacturing tech startup, has raised £2.2 million in a seed funding round to commercialise a working prototype of a new photolithography device that uses light to enable rapid, reconfigurable production of photonic chips with enhanced three-dimensional control. The raise aims to help move photonic chip manufacturing from laboratory demonstration towards higher-volume production, a development that could matter for data centres, AI training and other light-based systems.
Why it matters
Silicon chips are approaching physical limits on speed and heat dissipation, driving interest in photonic chips that transmit data with photons rather than electrons. Photonics can offer higher transmission speeds without the same overheating issues, but widespread adoption has been constrained by complex and costly manufacturing processes.
Cnuic’s approach seeks to lower those barriers by providing a new way to pattern three-dimensional photonic structures more quickly and with reconfigurability. If it scales, the technology could reduce cooling and electricity costs for large data centres and ease communication bottlenecks between processors during AI model training. It also has implications for components beyond compute, including optical lenses and waveguides used in AR and VR devices.
Inside the product
Cnuic has built a working prototype of a photolithography device that exploits the properties of light to pattern structures in three dimensions. The company says the system enables rapid, reconfigurable production of photonic components such as metalenses, 3D photonic crystals, AR and VR waveguides, and flexible gratings. The emphasis is on manufacturing flexibility — changing patterns without needing entirely new masks or tooling — which could shorten development cycles and lower unit costs for specialty optical parts.
Technical claims in the announcement focus on enhanced 3D control and the potential to increase throughput of photonic chip production. Independent verification and a demonstration of scaling to commercial volumes will be key next steps to judge how the prototype performs against incumbent semiconductor lithography techniques.
Who are the investors?
The round totals £2.2 million and is led by Tensor Ventures, with participation from Blank Space Ventures, Silicon Roundabout Ventures, Phasechange, SANDS and Superlative.
Tensor Ventures presented the investment as a bet on deep tech manufacturing innovation and on Europe’s position in the global chip industry. In the announcement, Ondřej Lipold and Martin Drdúl, Tensor Ventures, said:
Cnuic’s technology can democratise the production of photonic chips in much the same way that PCs democratised computing power. From a deep tech perspective, this is a completely new technology and a major breakthrough that could mean a whole new role for Europe in the semiconductor industry.

Founder perspective
In the announcement, Omar Durrani, Co-founder at Cnuic, said:
Every major leap in human capability has come from learning to use a new medium better. We learned to use electrons. Now we are learning to use light. Cnuic is building the tools that make that possible at scale.
Durrani’s comment frames the company’s aim as tooling for a broader industry transition from electronic to photonic information processing. The next phase for the team will be translating prototype performance into reproducible manufacturing metrics and commercial partnerships.
The bigger picture
Cnuic’s raise and prototype fit into a broader push for more onshore capability in advanced hardware and photonics in the UK and Europe. Governments and investors are increasingly attentive to supply-chain resilience and to reducing reliance on distant foundries for specialised components. Photonic chips intersect with several high-growth areas — data infrastructure, AI hardware, and AR/VR — which helps explain investor interest from firms focused on deep tech.
Whether Cnuic can scale its photolithography approach will determine its impact: laboratory breakthroughs do not always translate into cost-effective, high-volume production. Still, the round highlights continuing appetite among tech investors for hardware-focused startups that address bottlenecks in next-generation computing and optical systems.
