Image of FIG. 1.
FIG. 1.

(Color online) Micro-photoluminescence spectrum for a laser detuning with the exciton energy δ = EL  − EX of −74 μeV (a) and −6 μeV (b). (c) Intensity of the QD resonant emission as a function of δ. The solid line is the sum of two Lorentzian fits (dashed lines) of width 4.4 μeV and 5.0 μeV, separated by 12 μeV, corresponding to the two linear orthogonal polarizations A and B, of the neutral exciton. Inset: Scheme of the tilted QD axes A and B with respect to the main crystallographic axes [110] and , labeled as X and Y.

FIG. 2.

(Color online) (a), (b), and (c) High-resolution Fourier transform spectroscopy of the resonant emission of the exciton line B, at δ = 6 μeV, for decreasing powers corresponding, respectively, to Ω2 = 155 ns−2, 64.6 ns−2, and 11.6 ns−2. Fit (solid line) to the first-order correlation function g (1)(τ) with T 1 = 320 ps, T 2 = 410 ps, and TL  = 10 ns. The background level is indicated with a dashed line. (d), (e), and (f) Corresponding calculated resonant emission spectrum deduced by inverse Fourier transform of the g (1)(τ) function (Ω2 = 155 ns−2, 64.6 ns−2, and 11.6 ns−2, respectively). The radiative-limit of width 2 μeV is schematized by a rectangular form and superimposed on each spectrum.

FIG. 3.

(Color online) Intensity correlation measurements of the RE under resonant excitation of the exciton line B, for a power corresponding to Ω2 = 2 ns−2. Fit (solid line) to the second-order correlation function g (2)(τ) with T 1 = 320 ps and T 2 = 410 ps.
