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.”
C-PIC Manager, Callum Littlejohns
