Molecular beam epitaxy of wafer-scale O-band InAs/InGaAs quantum dots on GaAs for quantum photonics
Pavel S. Avdienko, Lukas Hanschke, Quirin Buchinger +13
We report a scalable molecular beam epitaxy strategy to achieve a low density of O-band electrically tunable InAs/InGaAs quantum dots (QDs) on GaAs(001) substrates. Our approach is…

Enhanced spectral range of strain-induced tuning of quantum dots in circular Bragg grating cavities
Ivan Gamov, Matthias Sauter, Samuel Huber +5
Tunable sources of entangled and single photons are essential for implementing entanglement-based quantum information protocols, as quantum teleportation and entanglement swapping…
