Fig. 5: Purcell effect and single-photon emission characteristics of single QDs coupled to MPhC nanocavities.
From: Cavity quantum electrodynamics with moiré photonic crystal nanocavity
a PL spectra of the QD as it is tuned across the MPhC nanocavity with a = 310 nm and δd = 16 nm by changing the measurement temperature. b The fitted intensity of the QDs corresponding to the spectra in (a), where ΔE is the QD-cavity mode detuning energy. c The decay curves of QDs in bulk material, non-resonance, and resonance with the cavity and the IRF of system. d The statistical analysis of the lifetimes for QDs in bulk, in resonance, and non-resonance with MPhC nanocavities. The black line is the average lifetime of QDs in bulk. e Second-order correlation measurement of single photons emitted by the QD in bulk (left) and the QD coupled with MPhC nanocavities (right).
