Influence of molecular beam effusion cell quality on optical and electrical properties of quantum dots and quantum wells
G. N. Nguyen, A. R. Korsch, M. Schmidt +7
Quantum dot heterostructures with excellent low-noise properties became possible with high purity materials recently. We present a study on molecular beam epitaxy grown quantum wel…
Effect of electric current on optical orientation of electrons in AlGaAs/GaAs heterostructure
O. S. Ken, E. A. Zhukov, I. A. Akimov +10
The effect of a lateral electric current on the photoluminescence H-band of an AlGaAs/GaAs heterostructure is investigated. The photoluminescence intensity and optical orientation…
On-chip nanomechanical filtering of quantum-dot single-photon sources
Xiaoyan Zhou, Ravitej Uppu, Zhe Liu +6
Semiconductor quantum dots in photonic integrated circuits enable scaling quantum-information processing to many single photons and quantum-optical gates. On-chip spectral filters…
Lifetimes and quantum efficiencies of quantum dots deterministically positioned in photonic-crystal waveguides
Xiao-Liu Chu, Tommaso Pregnolato, Rüdiger Schott +4
Interfacing single emitters and photonic nanostructures enables modifying their emission properties, such as enhancing individual decay rates or controlling the emission direction.…
Deterministic positioning of nanophotonic waveguides around single self-assembled quantum dots
Tommaso Pregnolato, Xiao-Liu Chu, Tim Schröder +5
The capability to embed self-assembled quantum dots (QDs) at predefined positions in nanophotonic structures is key to the development of complex quantum photonic architectures. He…
Suspended Spot-Size Converters for Scalable Single-Photon Devices
Aslı D. Uğurlu, Henri Thyrrestrup, Ravitej Uppu +6
We report on the realization of a highly efficient optical spot-size converter for the end-face coupling of single photons from GaAs-based nanophotonic waveguides with embedded qua…
