We are pleased to announce our latest investment in Opsydia, a University of Oxford spinout using adaptive optics technology for the direct laser writing of features in transparent materials.
Oxford, UK, 31st July 2025 – OPSYDIA Limited, a spin out from Oxford University using adaptive optics technology for direct laser writing of features in transparent materials, announces the closing of pre-Series A funding round led by Foresight Group and Parkwalk Advisors, along with the University of Oxford Innovation Fund and Oxford University.
The funds will be used to rapidly bring to market and deploy OPSYDIA’s waveguide writing technology, for deployment into optical interconnects in high bandwidth and high-density applications. Nigel Vaughan, Executive Chairman of OPSYDIA, observed “The increase in datacentre bandwidth demands driven by AI and other applications will require a new approach to optical connectivity. OPSYDIA’s adaptive optic approach supports these goals by allowing users to directly write waveguides in optical connectors right to the edge and with extremely low insertion loss. Our approach also supports emerging density demands as we have demonstrated arrays of waveguides that are likely to dramatically improve bandwidth performance”.
Alun Williams, Investment Director at Parkwalk Advisors said “Overcoming the impending bottlenecks industry is facing due to the surge in bandwidth demand driven by AI applications requires innovative thinking on topics such as connectivity and co-packaging of optics. OPSYDIA is uniquely poised to deliver solutions addressing these and other challenges”.
Prof. Martin Booth, Founding Scientist at OPSYDIA stated “As device architectures become more complex, new platforms are needed to continue driving innovation. Our systems level approach allows us to optimise device fabrication by adapting the ultrafast laser fabrication based upon precision microscopic measurements. This unique capability provides exciting opportunities for the field.”
