Research data supporting "Robust consistent single quantum dot strong coupling in plasmonic nanocavities"

data from open access paper with title listed. Fig. 1f: Average scattering spectra of >800 NPoMs sorted into bins which all show clear energy splitting of coupled modes. Histogram (black dashed) and average spectra are sorted according to energy of lower (ω_-) and upper (ω_+) polaritons. Fig. 1g: Typical photoluminescence spectrum (red) of monolayer QD film in (c), with spectral distribution of exciton peak at different locations (expanded in inset). Fig. 2b: Photoluminescence spectra of weak- (red) and strong- (purple) coupled excitons, selected from measurements on >800 NPoMs. Fig. 2c,d: Slow time evolution of photoluminescence spectra of (c) exciton- and (d) polariton-type NPoMs. Fig. 3a: Correlation of typical photoluminescence (orange) and scattering (blue) spectra of 7 NPoMs vs cavity detuning. Fig. 3b: Extracted anti-crossing curve of polariton (see text). Fig. 3c,d: Rabi splitting energies extracted from (c) scattering spectra (>600 NPoMs) and (d) photoluminescence (>350 NPoMs). Fig. 4a: Experimental (top) and simulated (bottom) scattering and PL spectra of single quantum dot-plasmonic nanocavity in strong coupling regime of near zero detuning. Fig. 4b: Simulated scattering and PL spectra of single quantum dot in plasmonic nanocavity for increasing coupling strengths shown. Fig. 5c,d: Emission spectra under (c) optical and (d) electrical excitation. Fig. 5e: Evolution of polariton modes over time as the plasmon mode blueshifts during facet reshaping.
