The aim of this course is to equip graduate students with the skills necessary to carry out practical design exercises and produce integrated optical components. The course will introduce the numerical tools used to simulate waveguides, the material systems and parameters in common use and typical device configurations. Students will develop a practical understanding of basic integrated components, including: Y-junctions, directional couplers, interferometers, and multi-mode interferometers (MMIs). The course will also consider typical approaches towards monolithic and hybrid integration.
