Nonlinear Optics in 2D Materials

Atomically thin crystals forming a 2D sheet exhibit astonishing physical, chemical, and optical properties. The emergence of these materials, such as graphene, transition metal dichalcogenides, and others, has sparked widespread interest in the photonics community. Besides featuring an unprecedented performance for linear light-matter interactions, these materials also exhibit extraordinary nonlinear optical properties. A better understanding of both the fundamental physics and the practical implementation of nonlinear optical phenomena in 2D crystals would allow fully exploiting the great potential of this field. The aim of this special topic is to focus on cutting-edge research that provides new insights into the nonlinear optical properties of 2D materials and strongly advance the knowledge and expertise in this exciting research branch.
