Fig. 2: Photoluminescence characterization of single quantum dot (QD) coupled to plasmonic nanocavity.

a Spontaneous emission process in weak- (red) and strong- (purple) coupling regimes of nanoparticle-on-mirror (NPoM) nanocavity coupled to single quantum dot, under non-resonant pumping (blue). b Photoluminescence spectra of weak- (red) and strong- (purple) coupled excitons, selected from measurements on >800 NPoMs. Slow time evolution of photoluminescence spectra of (c) exciton- and (d) polariton-type NPoMs. e Field distribution of single QD-NPoM construct at upper and lower polariton resonances. f Simulated scattering spectra of single QD-NPoM as QD is laterally shifted by Δx from center of NPoM (inset in c).
