Linear and nonlinear optical propagation in 2D materials

Abstract

Recently, a lot of effort has been dedicated to developing next-generation optoelectronic devices based on two-dimensional materials, thanks to their unique optical properties that are significantly different from those of their bulk counterparts. In order to implement high-performance nanoscale optical devices, an in-depth study of how linear and non-linear propagation occurs in two-dimensional materials is required. Here, we focus on the theory behind the propagation of electromagnetic waves in two-dimensional materials as well as emerging applications in the fields of electronics, optics, sensors, which are summarized and discussed in the paper.
