Image of FIG. 1.
FIG. 1.

(a) Schematic of the device under investigation. (b) photoluminescence spectra of the device for increasing excitation powers. Spectra are vertically and horizontally shifted for clarity. The shaded spectrum presents the emission profile of similar device embedding a large density of QDs shining the CTP mode.

FIG. 2.

(a) and (b) Emission intensity for the X line as a function of time for three excitation powers. (a) Experiment and (b) theory. (c) Top: measured autocorrelation function as a function of delay for two excitation powers. Middle: calculated contributions to the autocorrelation function : the shaded curves are the +12 ns and −12 ns delay peaks, zero delay peak. The bold line is the sum of these contributions. Bottom: calculated for two excitation powers.

Image of FIG. 3.
FIG. 3.

(a) Experimentally measured number of collected photon per excitation pulse as a function of excitation power for the X (solid square) and XX (open circles) line. The thin line represents the number of collected photons for X corrected for multiphoton emission. (b) Quality factor of the bidimensional Tamm plasmon mode as a function of the gold thickness calculated with a transfer matrix method. (c) Calculated Purcell factor as a function of the disk diameter for various disk thicknesses. (d) Theoretical extraction as a function of the disk diameter, for various inhibition rates γ and two gold disk thicknesses (40 nm and 50 nm).
