CORNERSTONE is a license free, open source Silicon Photonics rapid prototyping foundry based in the UK. Our open access and license free model differentiates us from other foundries. Our prototyping platform uses industry-compatible, deep-UV projection lithography meaning you can seamlessly scale up production volumes via your favourite commercial foundry. The platform retains device-level innovation capability and flexibility in its process flows, making it the perfect choice for researchers who want to try out innovative designs or evaluate new photonic circuits.
CORNERSTONE offers 3 different silicon-on-insulator platforms and a silicon nitride platform via a multi-project-wafer service. We will soon be launching 4 exciting new silicon based platforms based on demand from users, all of which will be available over the next year, find out more!
