Description:
(abstract)Metasurfaces allow light to be manipulated at the nanoscale. Integrating metasurfaces with transition metal dichalcoge- nide monolayers provides additional functionality to ultrathin optics, including tunable optical properties with enhanced light−matter interactions. In this work, we demonstrate the realization of a polaritonic metasurface utilizing the sizable light−matter coupling of excitons in monolayer WSe2 and the collective lattice resonances of nanoplasmonic gold arrays. We developed a novel fabrication method to integrate gold nanodisk arrays in hexagonal boron nitride and thus simultaneously ensure spectrally narrow exciton transitions and their immediate proximity to the near-field of array surface latticeresonances. In the regime of strong light−matter coupling, the
resulting van der Waals metasurface exhibits all key characteristics of lattice polaritons, with a directional and linearly polarized far-
field emission profile dictated by the underlying nanoplasmonic lattice. Our work can be straightforwardly adapted to other lattice geometries, establishing structured van der Waals metasurfaces as means to engineer polaritonic lattices.
