Optics and photonics of quasicrystals

Abstract

This review paper discusses current theoretical and experimental studies related to photonic quasicrystals, their production, structure, properties, and applications. Currently, the study of quasicrystals is one of the promising directions in working with small structures. Quasicrystals have become a catalyst for transformative advances in various fields, including optics. The materials from which quasicrystals can be obtained are extremely diverse, it can be either two–layer folded graphene, where the parameters of the interlayer interaction are determined by the angle of rotation of one layer relative to the other, or others. In addition, laser technologies are currently being used to create complex two-dimensional quasicrystalline lattices, superlattices, and Moire lattices. There are works in which it is possible to obtain quasicrystalline lattices with an order of symmetry from 2-fold to 22-fold by repeatedly exposing a one-dimensional interference pattern to several fixed angles of rotation of the sample, as well as more complex structures. This allows for the appearance of a wide range of complex nanostructures with adjustable periodicity and controlled symmetry.
