Cavity-enhanced radiative emission rate in a single-photon-emitting diode operating at 0.5 GHz
David J. P. Ellis, Anthony J. Bennett, Samuel J. Dewhurst +3
We report the observation of a Purcell enhancement in the electroluminescence decay rate of a single quantum dot, embedded in a microcavity light-emitting-diode structure. Lateral…
Oxide-apertured microcavity single-photon emitting diode
D. J. P. Ellis, A. J. Bennett, A. J. Shields +2
We have developed a microcavity single-photon source based on a single quantum dot within a planar cavity in which wet-oxidation of a high-aluminium content layer provides lateral…
Observation of the Purcell effect in high-index-contrast micropillar
A. J. Bennett, D. J. P. Ellis, A. J. Shields +3
We have fabricated pillar microcavity samples with Bragg mirrors consisting of alternate layers of GaAs and Aluminium Oxide. Compared to the more widely studied GaAs/AlAs micropill…
Oscillatory D'yakonov-Perel' spin dynamics in two dimensional electron gases
W. J. H. Leyland, R. T. Harley, M. Henini +4
Optical pump-probe measurements of spin-dynamics at temperatures down to 1.5K are described for a series of (001)-oriented GaAs/AlGaAs quantum well samples containing high mobility…
Surface-acoustic-wave-driven luminescence from a lateral p-n junction
J. R. Gell, P. Atkinson, S. P. Bremner +9
The authors report surface-acoustic-wave-driven luminescence from a lateral p-n junction formed by molecular beam epitaxy regrowth of a modulation doped GaAs/AlGaAs quantum well on…
Surface acoustic wave-induced electroluminescence intensity oscillation in planar light-emitting devices
Marco Cecchini, Vincenzo Piazza, Fabio Beltram +5
Electroluminescence emission from surface acoustic wave-driven light-emitting diodes (SAWLEDs) is studied by means of time-resolved techniques. We show that the intensity of the SA…
