We have demonstrated efficient production of triggered single photons by coupling a single
semiconductor quantum dot to a three-dimensionally confined optical mode in a micropost …

The authors report on Al As∕ Ga As micropillar cavities with unprecedented quality factors
based on high reflectivity distributed Bragg reflectors (DBRs). Due to an increased number …

Spontaneous emission of quantum dot systems in laterally structured microcavities that
exhibit photon confinement in all three directions has been studied by time-resolved …

How small can a laser be made? What characteristic properties must a device possess to
still be called a laser? How can one prove laser action in the limiting cases of single-emitter …

The spontaneous emission of an excited atom surrounded by different materials is studied in
the framework of a semiclassical approach, where the transition dipole moment acts as the …

Neuromorphic computing has received considerable attention as promising alternatives to
classical von Neumann computing architectures. An attractive concept in this field is …

We report on the realization of a dense, large-scale array of 900 quantum dot micropillar
