The course is postponed from 10-14 January to 11-15 April due to evolving COVID situation in Belgium.

The registered participants can cancel their registration by sending an email to

No action is necessary from those registered participants who intend to join on the new date for the course. We will keep you updated.

In April, the course may extend the COVID-reduced course size from 15 participants to 25 participants.

Stay safe!

silicon photonics chips

What is covered in the course?

The Specialist Course on Silicon Photonics Design goes from ideation to characterization of a working silicon photonics chip.

The course focuses on the process to translate a photonic circuit idea into a working chip, going from schematic design and circuit simulation to layout, routing, and interactive design rule checking.

As part of the course, the participants get the opportunity to actually tape out a design that will be fabricated with an e-beam prototyping service and characterized. Based on these results, the design can be improved and submitted to a wafer-scale multi-project-wafer run of which 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.

The course is full. We may decide to extend the COVID-reduced course capacity from 15 participants to 25 participants depending on the situation in April. You can click the below button to join the waiting list.
