What is covered in the course?

The Specialist Course on Silicon Photonics Design is a comprehensive program that covers the entire process of developing a functional Silicon Photonics chip – from ideation to characterization.
The course emphasizes transforming a photonic circuit concept into a functional chip, including schematic design, circuit simulation, layout, routing, and interactive design rule checking.
During the program, participants have the opportunity to create a design that will be fabricated using an e-beam prototyping service. The design will then be characterized, after which the results will be used to improve the design. Finally, the improved design will be submitted to a wafer-scale multi-project-wafer run, and the participants will receive the final chips.

Who can benefit from it?

The hands-on course is designed for researchers and engineers with a fundamental understanding of photonic integrated circuits.
