Company profile

Salience Labs

Oxford company developing photonic processing chips that combine optical and electronic layers for high-throughput computing workloads.

Company overview

Based at Milton Park in Oxfordshire, Salience Labs develops all-optical circuit switches for AI and datacentre infrastructure. The company uses its proprietary silicon photonics technology to create fully integrated switches that address data movement bottlenecks. Its products, such as the OC-32M all-optical switch module, aim to reduce network latency and power consumption compared to traditional electrical switches, while also lowering costs by eliminating the need for optical transceivers. The technology is designed to support high-speed interfaces and scale with future network bandwidth requirements. Salience Labs' approach leverages established semiconductor manufacturing processes for high-volume production. The company, which also has offices in Germany and the US, is backed by several venture capital firms including Oxford Science Enterprises, Cambridge Innovation Capital, and Applied Ventures. It describes its technology as the result of over ten years of research into silicon photonics.
