Computational modeling of nonlinear optical response of 2D-3D heteromaterials

Abstract

Remarkable physical properties of two-dimensional (2D) materials provide significant potential for novel photonic devices, many of which rely on nonlinear optical effects in these 2D materials. Here we use a theoretical and computational approach we have recently introduced to describe the linear and nonlinear optical physics of nanostructured 2D materials embedded in periodic structures containing regular three-dimensional (3D) optical media, such as diffraction gratings and metamaterials. Thus, we use the proposed method to demonstrate enhanced nonlinear optical interactions in periodic photonic nanostructures via resonant excitation of phase-matched waveguide modes, enhanced nonlinearity of nanostructures containing graphene and other 2D nanomaterials, and Fano resonances for increasing the efficiency of 2D-3D heteromaterials.
