SC454 - Hands-on: Introduction to Silicon Photonics Circuit Design

Monday, 07 June
03:00 - 07:00

Short Course Level: Beginner


Wim Bogaerts, University of Ghent, Belgium​

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. In that period, they will also get the opportunity to create a small design that will be fabricated using the e-beam technology developed by the Canadian SiEPIC program. This design will be characterized and the measurement data will be made available on the same learning platform for analysis.

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. Also, they can go through the entire process of actually creating a design and analyzing the results of the measurements.

Short Course Benefits:

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.

Instructor Biography:

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).
