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… Expand

Defect-Induced Photoluminescence Blinking of Single Epitaxial InGaAs Quantum Dots
TLDR
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. Expand
Photophysics of quantum emitters in hexagonal boron-nitride nano-flakes.
TLDR
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. Expand
Optical control of spectral diffusion with single InAs quantum dots in a silver-embedded nanocone.
TLDR
The temporal fluctuations in peak energy of photoluminescence can be effectively suppressed by strong illumination and it is found that the dot emission exhibits stable non-classical nature with the strong anti-bunching behavior after this stabilization. Expand
Combined atomic force microscopy and photoluminescence imaging to select single InAs/GaAs quantum dots for quantum photonic devices
TLDR
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.
TLDR
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.

Microfiber-microcavity system for efficient single photon collection.
TLDR
This bright fiber-coupled single photon sources based on InAs quantum dots are demonstrated through the k-vector matching between a microfiber mode and a normal mode of the linear photonic crystal cavity, providing a promising route for efficient direct fiber collections of single photons for quantum information processing.
