Nonlinear optics in 2D materials enhanced by plasmon modes in Dirac semimetals, Weyl semimetals, and 3D topological insulators
Abstract
Our goal is to study the dependence of the nonlinear optical selection rules, phase matching, energy detunings, efficiency of the nonlinear optical effects, such as sum frequency generation (SFG), difference frequency generation (DFG), four-wave mixing (FWM), etc., on the geometry and symmetry of the nanoparticles, the symmetry of the crystal structure of the 2D nonlinear materials (e.g. inversion symmetry), the size of the atoms in the 2D nonlinear materials (Stark effect is typically stronger for larger atoms), strain and-or electric field applied to the 2D nonlinear materials, confinement of excitons in the 2D nonlinear materials (i.e. quantum dots), and a variety of impurities and defects inside the 2D nonlinear materials.
