Semi-automatic engineering and tailoring of high-efficiency Bragg-reflection waveguide samples for quantum photonic applications
(2018-01-25) - Journal article
Semiconductor alloys of aluminum gallium arsenide (AlGaAs) exhibit strong second-order optical nonlinearities. This makes them prime candidates for the integration of devices for classical nonlinear optical frequency ...
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 ...
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 ...
Optical tuning of the charge carrier type in the topological regime of InAs/GaSb quantum wells
(2018-07-16) - Journal article
We study the optical tunability of the charge carrier type in InAs/GaSb double quantum wells with its type-II broken band alignment and inverted band structure. Under constant optical excitation, the majority charge carrier ...
Toward scalable boson sampling with photon loss
(2018-06-06) - Journal article
Boson sampling is a well-defined task that is strongly believed to be intractable for classical computers, but can be efficiently solved by a specific quantum simulator. However, an outstanding problem for large-scale ...
