Photon-number-resolved experiments: From the photon statistics of nanophotonic devices to quantum-optical studies of a single quantum dot (Conference Presentation)
Author(s): Martin von Helversen

Paper Abstract

Quantum photonics benefits from the scientific advances in the development of quantum light sources. To gain inside into the underlying physical processes of light generation, we use photon-number-resolving (PNR) transition edge sensors (TESs), which are able to directly access the photon-number distribution of nanophotonic devices. We present results on the transition from thermal to coherent emission of two different classes of microlasers: electrically driven bimodal quantum dot micropillar lasers and exciton polariton lasers. Furthermore, the photon number distribution of deterministically fabricated quantum dot based single-photon sources is investigated to explore the single-photon purity and indistinguishability of photons emitted by these sources.
