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…
Electrically tunable orbital coupling and quantum light emission from O-band quantum dot molecules
P. S. Avdienko, L. Hanschke, Q. Buchinger +10
We present the observation of electrically tunable quantum coupling of orbital states in individual InAs/InGaAs quantum dot molecules emitting in the telecom O-band (~1300 nm). By…
