Welcome to the CORNERSTONE website

CORNERSTONE is a new fabrication capability that can provide competitive prices for both active and passive silicon photonic devices. The CORNERSTONE team, headed up by Professor Graham Reed at the University of Southampton, aims to offer up to 6 passive calls and 2 active calls per year via a multi-project-wafer (MPW) service. With a track record of world-leading results, and supported by some of the world’s best academic fabrication facilities for microfabrication and high-spec nanofabrication, CORNERSTONE is also open to bespoke fabrication runs at affordable prices, with a flexibility that may not be accessible at conventional foundries. Through the use of lithography techniques such as advanced projection lithography and direct write e-beam lithography (by request), CORNERSTONE can offer both an industry compatible fabrication capability, and design flexibility essential for research and prototyping purposes.

If you are interested in participating in the project, you can find the technical information, inlcuding design rules for all MPW calls, here. Alternatively you can email us at This email address is being protected from spambots. You need JavaScript enabled to view it..
