Quantum mechanics promises to have a strong impact on many aspects of research and
technology, improving classical analogues via purely quantum effects. A large variety of …

Long-distance quantum communication and computation is based on the exchange of
information via photons as flying qubits. In all foreseen implementations, from quantum …

In this work, we develop and study single-photon sources based on InGaAs quantum dots
(QDs) emitting in the telecom O-band. Quantum devices are fabricated using in situ electron …

By metal-organic vapor-phase epitaxy, we have fabricated InGaAs quantum dots on GaAs
substrate with an ultra-low lateral density (⁠< 10 7 cm− 2⁠). The photoluminescence …

We report on the experimental demonstration of triggered single-photon emission at the
telecom O-band from In (Ga) As/GaAs quantum dots (QDs) grown by metal-organic vapor …

The concept of tunneling injection was introduced in the 1990's to improve the dynamical
properties of semiconductor lasers by avoiding the problem of hot carrier injection which …

We report on temperature-dependent investigations of single metal-organic vapor phase
epitaxy-grown In (Ga) As/GaAs quantum dots at wavelengths above 1 μm. Here, two types of …

InAs quantum dots grown on a GaAs substrate have been one of the most successful
semiconductor material systems to demonstrate single-photon-based quantum optical …

We investigate the cascaded emission of photons from low-density InGaAs/GaAs quantum
dots grown by metal-organic vapor-phase epitaxy that are intentionally redshifted toward …

Hereby, we present a comprehensive experimental and theoretical study of the electronic
structure and optical properties of excitonic complexes in strain-engineered InGaAs/GaAs …
