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.
Join us at PIC Bootcamp
PIC Bootcamp is an immersive, industry-led programme delivering practical skills in silicon photonics. Gain hands-on experience in PIC design, fabrication, testing, and packaging, guided by experts from leading organisations. Begin with an Introduction to Photonic Integrated Circuits (PICs), then move on to hands-on modules that bring core PIC functionalities to life.
Developed by CORNERSTONE, Bay Photonics, Wave Photonics, and Anchored In Ltd, the Bootcamp connects theory with real-world PIC development.
Who it’s for: Researchers, industry professionals, start-ups, and early-career engineers building careers in photonics.
What you gain: Job ready technical skills, experience with industry standard tools, expert insight into real-world PIC development, and valuable connections across the photonics ecosystem.
