Leeds-based chip designer Optalysys, which is developing optical chips that use light instead of electricity to perform calculations, raised a £21M Series A
Leeds-based company pushes its innovative technology to unlock one of greatest challenges in data security
Context & Ripple Effects
Optalysys's £21M Series A lands in a funding lineage that has been building for years: Boston-based Lightmatter went from an $11M Series A in 2018 to an $80M Series B by 2021 for its light-signal AI chips, while UK compatriot Rockley Photonics pulled in a $65M growth round on top of more than $290M total for integrated photonic chipsets.
More recently the money has broadened beyond AI acceleration: OpenLight, which designs custom application-specific silicon photonic chips, followed a $34M Series A with a $50M Series A extension aimed at data center interconnects. Optalysys extends that pattern in a different direction — using light for the computation itself, pointed at data security rather than interconnect bandwidth.
First-order effects
- The £21M gives Leeds-based Optalysys the runway to push its optical computation chips from development toward its stated target of solving hard data-security problems, making it the most recent UK entrant in a photonic funding wave that already includes Rockley Photonics.
Second-order effects
- Investors who tracked Lightmatter's progression from an $11M Series A to an $80M Series B now have a second compute-focused optical-chip bet to price, while interconnect-focused players like OpenLight compete for the same photonics talent and fab capacity from a different application angle.
Third-order effects
- If successive rounds keep landing, photonics looks set to split into two separately funded tracks — interconnect specialists like OpenLight and compute plays like Optalysys and Lightmatter — with data security emerging as a demand driver distinct from AI throughput.
The trend: Photonic chip startups are sustaining a multi-year, multi-round capital cycle, with investment spreading from AI acceleration into interconnects and now light-based computation for data security.
