CORNERSTONE is an open source, license free silicon photonics rapid prototyping foundry. We offer a plethora of different platforms to support a wide range of applications ranging from telecoms to sensing, LiDAR, quantum and more. Each platform possesses a standard component library to lower the barrier to entry for non-photonics experts. We will gladly experiment and try new things for the benefit of our users. This flexible approach helps us to support early stage R&D projects and successfully fabricate proof of concept prototypes.
