Controlling the charge environment of single quantum dots in a photonic-crystal cavity

Blandine Alloing, Carl Zinoni, Laurent Balet

We demonstrate that the presence of charges around a semiconductor quantum dot (QD) strongly affects its optical properties and produces nonresonant coupling to the modes of a microcavity. We show that, besides (multi)exciton lines, a QD generates a spectr ...

Recombination dynamics of single quantum dots in a fiber system at telecommunication wavelengths

Blandine Alloing

Coupling the emitted light from single quantum dots into an optic fiber has been demonstrated as a. plug and play' single-photon Source. In this work, lifetime dynamics measurements were performed with two time-delayed femtosecond optical pulses at differe ...

Cavity-enhanced photonic crystal light-emitting diode at 1300 nm

Blandine Alloing, Laurent Balet

We report direct evidence of enhanced spontaneous emission in a photonic crystal light-emitting diode (LED) at telecom wavelength (lambda similar to 1300 nm). This result is crucial to obtain an electrically driven single photon source with high extraction ...

"Plug and Play" single photons at 1.3 mu m approaching gigahertz operation

Blandine Alloing

We report a "plug and play" single photon source, fully integrated with an optical fiber, emitting at 1.3 mu m. Micropillars were patterned on a single layer InAs quantum dot wafer to guarantee a single pillar per fiber core. The single exciton peak filter ...

Growth-interruption-induced low-density InAs quantum dots on GaAs

Blandine Alloing

We investigate the use of growth interruption to obtain low-density InAs quantum dots (QDs) on GaAs. The process was realized by Ostwald-type ripening of a thin InAs layer. It was found that the optical properties of the QDs as a function of growth interru ...

Enhanced spontaneous emission in a photonic-crystal light-emitting diode

Blandine Alloing, Laurent Balet

We report direct evidence of enhanced spontaneous emission in a photonic-crystal (PhC) light-emitting diode. The device consists of p-i-n heterojunction embedded in a suspended membrane, comprising a layer of self-assembled quantum dots. Current is injecte ...

Towards a LED based on a photonic crystal nanocavity for single photon sources at telecom wavelength

Romuald Houdré, Blandine Alloing, Carl Zinoni, Laurent Balet, Nicolas Le Thomas

A fundamental step towards achieving an "on demand" single photon source would be the possibility of electrical pumping for a single QD and thus the integration of such a device in an opto-electronic circuit. In this work we describe the fabrication proces ...

Growth and characterization of single quantum dot devices for fiber-based quantum communications

Blandine Alloing

Single photon sources have recently attracted significant interest for their potential role in the future applications of quantum cryptography, and in the longer term, quantum computing. Among the different types of single photon emitters, semiconductor qu ...
