Abstract
In this course, we start hands-on with circuit design in silicon photonics. As fabrication technology is steadily improving, it becomes possible to implement more complex functionality as a circuit. Circuits are an abstraction where the function is defined as a connected network of functional components, with signals travelling between them. In this course, we learn how to compose hierarchical circuits from libraries of basic building blocks, use parametric circuit models and simulation in both frequency domain and time domain, and eventually 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).
During the four hours of the course, we start with the basic concepts of silicon photonics and learn about the fundamentals of design. You will also get familiar with the hands-on on-line learning environment based on Jupyter Python notebooks powered by Luceda Photonics’s IPKISS design tools. With these tools you can design and simulate different photonic circuits as if you would plan to fabricate them. You can use this environment during the course session and continue to use it freely for a few months after the conference.
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.
