"Computational Photonics and Topological Materials"

Abstract
In recent years it became clear that many photonic structures show interesting topological properties, which had simply been overlooked in the past. I will give an introduction into this fascinating topic and discuss various examples like topological photonic crystals and topological waveguide arrays. My focus will be on an elementar y discussion of the main results, where I will slightly deviate from the standard approaches and show how to apply rather intuitive concepts like the Brouwer degree, instead of falling back on more abstract mathematical concepts. Finally, I will discuss so me of the numerical approaches used to study topological photonic systems.
