Building on our long-standing commitment to open access, C-PIC is enabling true open-source collaboration in silicon photonics.

The Open Platform makes CORNERSTONE Foundry-compatible Process Design Kits (PDKs), components, and building blocks freely available, while also supporting contributions from the wider community.
Researchers, innovators, and organisations can now share and reuse trusted design elements in a single environment – shortening design cycles and creating an ecosystem where innovation scales, rather than being reinvented.

First releases include:

🔹 𝗦𝗢𝗜 𝟮𝟮𝟬 𝗻𝗺 𝗮𝗰𝘁𝗶𝘃𝗲 𝗣𝗗𝗞
🔹 𝗦𝗶𝗡 𝟯𝟬𝟬 𝗻𝗺 𝗣𝗗𝗞

Additional platforms – including Ge-on-Si, Suspended Si, SOI 340 nm, SOI 500 nm, and SiN 200 nm – will follow soon.

🤝 Community contributions are already shaping the platform, with designs from Compound Semiconductor Applications (CSA) Catapult, Tyndall National Institute, Università di Pavia, The University of Sheffield, and others.
We are also working with Wave Photonics, whose new PDK Management Platform is being used by CORNERSTONE to host and distribute our PDKs.
