The Technology
Compute hardware for high-performance workloads
What It Is
The Photonic Accelerator Unit (PAU) uses photons to perform computations. The shift in compute substrate — from electrons in silicon to light — sidesteps the thermal, power, and supply-chain constraints that conventional accelerators are now hitting.
Why It Matters
Compute-intensive workloads are now bound by physics. Power and heat are no longer engineering details — they dominate the economics of large-scale compute deployments.
A photonic substrate addresses these constraints at the foundation, rather than as an optimisation layered on top of an electronic system.
Design Principles
Compute happens in the photonic domain. The substrate is engineered for the operating regime PAU requires.
PAU is a general-purpose photonic compute platform. Use cases span AI inference, scientific compute, signal processing, and other workloads where the limits of silicon hardware are the bottleneck.
The fabrication path sits outside the leading-node silicon foundry bottleneck. Resilience is built in at the substrate level, not retrofitted at the system level.
The architecture is the subject of a US provisional patent filed at the USPTO in April 2026. Sole inventor; full continuation strategy planned as the technology matures.
Validation
Software simulation has validated the PAU architecture.
The next milestone is a tabletop prototype that demonstrates the architecture in hardware.
Further details are available under NDA.
