TL;DR: In this paper, the authors present room temperature, continuous wave operation of laser diodes based on whispering gallery mode microcylinder and microring resonators featuring an emission wavelength at around 1.3 μm and lasing thresholds of a few mA.

TL;DR: In this paper, the spin and density patterns of exciton-polariton condensates in strained planar cavities with a nonuniform energy landscape are shown to undergo fast nonequilibrium transformations under the conditions of pulsed resonant excitation.

TL;DR: This paper presents a systematic investigation of strain compensation schemes for InAs/AlSb superlattices (SLs) on GaSb substrates and finds that each approach yields layers with excellent crystal quality and minimal intermixing at the heterointerfaces as verified by high resolution x-ray diffraction analysis and transmission electron microscopy.

TL;DR: In this article , a new optically active solid-state spin-qubit based on a hole confined in a single InAs/GaAs quantum dot grown on an InGaAs metamorphic buffer layer emitting photons in the C-band was proposed and implemented.

TL;DR: The Wurzburg group as mentioned in this paper gratefully acknowledge the financial support by the German Federal Ministry of Education and Research via the funding “2D Nanomaterialien fur die Nanoskopie der Zukunft”.
