During hands-on exercises, you will learn how to accurately model and simulate various optical devices, which enables high-speed optical communication<\/em>. At the end of the course, students will gain practical experience in simulating photonic components by picking a small project<\/a> in which certain photonic devices will be optimized to achieve required specifications. These simulated devices find applications in Photonic Integrated Circuits (PICs) on chip-scale.<\/p>\n\n\n\n As an example of a project, Figure 1 below shows an electromagnetic wave propagating along a silicon waveguide and a 3 dB waveguide coupler.<\/p>\n\n\n A basic understanding of electromagnetics is helpful but not mandatory.<\/p>\n\n\n\n During the first half of the semester, different aspects of using COMSOL to design photonic components will be introduced starting from very basics. These lectures will consist of a short theoretical background review and hands on simulations (i.e. point source simulations, Young’s single\/double slit experiment demonstrations, photonic mode simulations of different waveguides (fiber, slit, etc.), wave propagation simulations, ..) to apply what was demonstrated. In the second half of the semester, the focus will be on designing full-scale photonic components (i.e. directional coupler, ring resonator, multi-mode interferometer, …), and students can work on their design projects individually.<\/p>\n\n\n\n The course will be taught in English.<\/p>\n\n\n\n You can navigate to find the Comsol models<\/a> that are used during the lectures, the basic workflow<\/a> to use Comsol, and the wiki<\/a><\/em> section for the common mistakes.<\/p>\n\n\n\n Presentation<\/em>: 15.12.2025<\/p>\n\n\n\n Deadline for the reports: <\/em>22.12.2025<\/p>\n\n\n\n![\"\"](\"https:\/\/blogs.ethz.ch\/ps_comsol\/files\/2025\/02\/waveguide_coupler-1024x855.png\")
