Polaritonic Metasurfaces

In this talk, I will discuss our recent progress in the area of polaritonics, and its role in advancing the field of metamaterials and metasurfaces. Tailored material resonances, based on excitons, phonons, magnons and electronic transitions, can be strongly coupled to light in engineered metastructures, unveiling new degrees of freedom for the control of light-matter interactions at the quantum limit and enhancing optical nonlinearities. In particular, I will discuss our recent progress on engineered surfaces and metasurfaces strongly coupled to 2D materials, and the resulting control of polaritons in the classical and quantum limit.
