Moir\'e Photonic Crystals: from Fabric to Magic

Abstract

Moir\'e patterns have recently become a very active field in nanophotonics. Those structures exhibit novel photonic properties unattainable with traditional photonic crystals. Especially, moir\'e magic configurations have been shown to allow intriguing slow light modes with zero group velocity. Starting from macroscopic moir\'e patterns in the everyday life, we will then shift to the subwavelength scale of moir\'e photonic crystals and detail some of their unusual properties.
