We use photon correlation measurements to study blinking in single, epitaxially-grown self-assembled InAs quantum dots situated in circular Bragg grating and microdisk cavities. The normalized second-order correlation function g(2)(\tau) is studied across eleven orders of magnitude in time, and shows signatures of blinking over timescales ranging from tens of nanoseconds to tens of milliseconds. The g(2)(\tau) data is fit to a multi-level system rate equation model that includes multiple non…

Defect-Induced Photoluminescence Blinking of Single Epitaxial InGaAs Quantum Dots

This defect-induced exciton quenching in epitaxial QDs, previously demonstrated also in colloidal nanocrystals, confirms that these two important semiconductor nanostructures could share the same PL blinking mechanism.

Photophysics of quantum emitters in hexagonal boron-nitride nano-flakes.

This study presents a systematic and detailed analysis of the photon statistics recorded for several individual emitters and indicates excitation-power-dependent non-radiative couplings to at least two metastable levels and confirms a near unity quantum efficiency.

Combined atomic force microscopy and photoluminescence imaging to select single InAs/GaAs quantum dots for quantum photonic devices

It is found that single quantum dots often appear in the vicinity of comparatively large topographic features, and it is anticipated that the approach of screening quantum dots not only based on their optical properties, but also their surrounding surface topographies, will be necessary to improve the yield of single quantum dot nanophotonic devices.

Single self-assembled InAs/GaAs quantum dots in photonic nanostructures: The role of nanofabrication.

Photoluminescence imaging is used to locate the positions of single InAs/GaAs quantum dots with respect to alignment marks with < 5 nm uncertainty, allowing us to measure their behavior before and after fabrication, and it is shown that atomic layer deposition can stabilize spectral diffusion of the quantum dot emission, and partially recover its linewidth.

Wigner Time Delay Induced by a Single Quantum Dot.

In the presence of electron-phonon interaction, deviations from Wigner's theory related to incoherent and strongly non-Markovian scattering processes which are hard to quantify via a detuning-independent pure dephasing time are observed.
