Multimode non-Hermitian framework for third harmonic generation in nonlinear photonic systems comprising 2D materials

Thomas Christopoulos, Emmanouil E. Kriezis, Odysseas Tsilipakos

Resonant structures in modern nanophotonics are non-Hermitian (leaky and lossy), and support quasinormal modes. Moreover, contemporary cavities frequently include 2D materials to e…
