Conservation of Pseudoangular Momentum in the Radiative Emission and Optical Excitation of Valley-Polarized Surface Lattice Resonances

Siamak Khorasani, Marc R. Bourgeois, David J. Masiello

Surface lattice resonances (SLRs) are collective polaritonic excitations in nanoparticle arrays, with band-edge states enabling symmetry-based control of radiation including scatte…
