Students will learn the physics and basic concepts of the main integrated photonic circuits devices. Specifically students will acquire advanced skills in the following areas: - Optical modelling tools - Mask layout tools - Design of optical devices and circuits - Data analysis techniques Students will get introduces to advanced design and simulation, computer based, tools, such as Lumerical or similar suites.
Prerequisiti
Advanced physics and optics concept. The course uses various computer software programs, and a background in basic programming is beneficial (e.g., MATLAB, Python).
Metodi didattici
The Course is based on lectures that illustrate the physics, the working principles, the operating characteristics, and the fabrication technology of the considered devices. Students will be required to use simulation software (s) to design and simulate the devices under interest. Additional software will be considered to design mask layouts.
Verifica Apprendimento
Written and oral test, with questions aiming at understanding which are the concepts acquired by the student and his/her ability to explain how the functional blocks of an integrated photonic device work. The minimum score to pass the exam is 18, the top one is 30 cum laude.
