CORNERSTONE
We make cutting-edge technology more open and available to improve everyday life.
CORNERSTONE is an open source, license free silicon photonics rapid prototyping foundry.
We offer seven photonics technology platforms to accommodate a broad spectrum of applications, including telecoms, sensing, LiDAR, quantum, and more. Each platform features a standard component library, helping to lower entry barriers and foster innovation by allowing engineers to focus on their applications. Our unique approach allows us to assist in the development of early-stage R&D projects and build proof-of-concept prototypes, helping to drive silicon photonics innovation.
CORNERSTONE Photonics Innovation Centre
CORNERSTONE is now officially an Innovation and Knowledge Centre, having secured £11m in funding from the Engineering and Physical Sciences Research Council (EPSRC) and Innovate UK. This funding ensures the continuation of our foundry service for the next 5 years while enabling us to expand and enhance 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
