Brings the future closer by turning your ideas into reality.

Find out more

CORNERSTONE is an open source, license free silicon photonics rapid prototyping foundry. We offer a plethora of different platforms to support a wide range of applications ranging from telecoms to sensing, LiDAR, quantum and more. Each platform possesses a standard component library to lower the barrier to entry for non-photonics experts. We will gladly experiment and try new things for the benefit of our users. This flexible approach helps us to support early stage R&D projects and successfully fabricate proof of concept prototypes.

CORNERSTONE Photonics Innovation Centre (C-PIC)

We are thrilled to announce that CORNERSTONE’s bid to become an Innovation and Knowledge Centre has been successful, securing £11m in funding from the Engineering and Physical Sciences Research Council (EPSRC) and Innovate UK, securing the foundry service for the next 5 years whilst also providing us with the opportunity to grow and expand our offerings to the community.

 

“C-PIC will enable CORNERSTONE to become more than just a foundry. We will launch a suite of technical and non-technical training, act as a united voice for the UK silicon photonics community to policy makers and the public and look to seed new interdisciplinary collaborations around the UK.”

“CORNERSTONE has been integral to my spin-out journey as I transform optical fibre-based inertial sensors into miniature chip-scale devices for the first time. From the design phase through to chip-testing, CORNERSTONE have offered advice throughout, supporting me as both an early career researcher and now as an entrepreneur.”
