Abstract

In this talk, we discuss our recent efforts in the context of polaritonic metasurfaces formed through nanophotonic engineering of metasurfaces coupled to 2D materials. In particular, we discuss our recent theoretical and experimental results in the context of hyperbolic polariton manipulation, valley exciton control, sorting and steering, and twisted bilayers for polariton canalization and extreme dispersion engineering arising in polaritonic metasurfaces based on TMDs and TMOs. During the talk, we will discuss the highly unusual light-matter interactions and potential opportunities of these systems for nanophotonic devices.
