Circularly Polarized Polariton Lasing from Spin‐Momentum Locking in Deformed Plasmonic Kagome Cavities

open access: yesAdvanced Materials, EarlyView.
This paper describes room‐temperature polariton lasing with high circular polarization from deformed plasmonic Kagome lattice cavities strongly coupled to colloidal CdSe nanoplatelets. Spin‐selectivity from cavity modes resulted in control over the handedness of circular polarization as well as the direction of polariton lasing, opening prospects for ...
