New for MPW #50:
Graphene Integration
This MPW run will also introduce a new Graphene Integration Beta Service, delivered in partnership with the Cambridge Graphene Centre at the University of Cambridge. The service provides early access to graphene-enabled photonic device fabrication within the CORNERSTONE process flow, allowing users to evaluate and prototype next-generation graphene-integrated PICs.
As part of the beta launch, the service will be offered at a significantly reduced introductory rate for this MPW run. Please download the Design Rules for further technical details, design guidance and pricing information.
