Polaritonic resonances in the family of 2D materials [1] can offer new and exciting opportunities in the control of light flow, both in the near- and far-field regime. In this talk, I will focus primarily on the control of light flow in the near-field, i.e. plasmon-polariton. I will discuss various strategies where the intensity and polarization of light, and the materials’ unique properties, can be exploited to control the propagation of plasmons. I will touch upon concepts such as topological effects in materials, dipole-plasmon coupling, temporal modulation, parametric and resonant amplification.
