Controlling the gain contribution of background emitters in few-quantum-dot microlasers
(2018-02) - Journal article
We provide experimental and theoretical insight into single-emitter lasing effects in a quantum dot (QD)-microlaser under controlled variation of background gain provided by off-resonant discrete gain centers. For that ...
On-chip light detection using monolithically integrated quantum dot micropillars
(2016-02-22) - Journal article
We demonstrate the on-chip detection of light using photosensitive detectors based on quantum dot (QD) micropillar cavities. These microscale detectors are applied exemplarily to probe the emission of a monolithically ...
Exciton-polariton trapping and potential landscape engineering
(2017-01) - Journal item
Exciton-polaritons in semiconductor microcavities have become a model system for the studies of dynamical Bose-Einstein condensation, macroscopic coherence, many-body effects, nonclassical states of light and matter, and ...
High quality factor GaAs microcavity with buried bullseye defects
(2018-05) - Journal article
The development of high quality factor solid-state microcavities with low mode volumes has paved the way towards on-chip cavity quantum electrodynamics experiments and the development of high-performance nanophotonic ...
Intrinsic and environmental effects on the interference properties of a high-performance quantum dot single-photon source
(2018-05-15) - Journal article
We report a joint experimental and theoretical study of the interference properties of a single-photon source based on a In(Ga)As quantum dot embedded in a quasiplanar GaAs microcavity. Using resonant laser excitation with ...
Talbot effect for exciton-polaritons
(2016-08-26) - Journal article
We demonstrate, experimentally and theoretically, a Talbot effect for hybrid light-matter waves - exciton-polariton condensate formed in a semiconductor microcavity with embedded quantum wells. The characteristic `Talbot ...
