Short Course Description:
In this course, we start hands-on with circuit design in silicon photonics. As fabrication technology is steadily improving, the emphasis in silicon photonic design is gradually shifting from component design to circuit design. We compose hierarchical circuits from libraries of basic building blocks, use parametric circuit models and simulation in frequency domain and time domain, and generate a circuit layout. We look into the effects of variability and imperfections on circuit performance using Monte-Carlo simulations, and learn how to design wavelength filter circuits based on Mach-Zehnder interferometers and arrayed waveguide gratings (AWG). The largest part of the course is hands-on, using an on-line learning environment based on Jupyter python notebooks powered by Luceda Photonics’s IPKISS design tools. The participants can use this environment during the course session and continue to use it for a few months after the course.
Through this course, the participants will become familiar with the overall design flow, and acquire an awareness of important do’s and don’t’s in photonic circuit design, especially in a high-contrast system such as silicon photonics. They will become familiar with circuit layout and simulation (time domain and wavelength domain) and the basics of integrated optical filter design.
Update: The scheduled silicon photonics fabrication run that would allow the course participants to have their own chip design fabricated has currently been put on hold. It is not guaranteed that the designs can be fabricated (and characterized). If the fabrication run will take place, it will be with considerable delay with respect to the original schedule. The course content on design, and access to the learning platform remains unaffected by this change.

Short Course Audience:
The course is aimed at researchers and engineers who are starting in integrated photonics, or want to scale up from component design to a more circuit-like methodologies. Familiarity with basic concepts of photonic integrated circuits (waveguides, directional couplers, …) is required.
This course will make use of the same fabrication process as SC432, but uses a different design platform. Participation in both SC432 and SC454 is possible but neither course is a prerequisite for the other.
Wim Bogaerts is professor in Silicon Photonics at Ghent University and IMEC, Belgium. He pioneered wafer-scale fabrication of silicon photonics, and his current research focuses on the challenges for large-scale photonic circuits, including design challenges such as variability. He co-founded Luceda Photonics in 2014 to market the design tools developed at Ghent University and IMEC. Today, he is again a full-time academic researcher, and a grant holder of the European Research Council (ERC).
