Abstract

This course introduces the foundations of electromagnetic wave dynamics in periodic structures, with an emphasis on topological band phenomena. We explore wave propagation in continuous and discrete spaces, and treat frequency and time as additional dimensions. We also examine how gain, loss and nonlinearities impact such systems and discuss how these principles enable advanced photonic devices.

Objective

By the end of the course, students will understand the principles of wave dynamics in periodic photonic systems and be able to analyze the topological properties of band structures. The students will be able to calculate the Berry phase and Chern numbers of photonic structures, classify the topology of bands, and test the bulk-boundary correspondence. Finally, we will learn how gain, loss, and nonlinearities act on the traditional band theory. Throughout the course, the students will engage in scientific communication, teamwork, creativity and learn how to interpret current literature on the topic.
