Abstract
Quantum Dots (QDs) are ideally sources of non-classical light – single and entangled photons. However, requirements for practical applications, such as integrated quantum information processing circuits, are far more demanding than the most of the current QD systems can deliver. Among the requirements are site-control, emission uniformity, spectral purity, and high QD symmetry. We have already shown that these properties are significantly improved by a Pyramidal QD system – site-controlled InGaAs QDs grown by Metalorganic Vapor Phase Epitaxy (MOVPE) in inverted pyramidal recesses etched in (111)B oriented GaAs substrates [1–2]. In this work, we show a further progress towards integration of Pyramidal QDs to the quantum optics circuits by presenting our QDs as electrically driven sources of non-classical light.
