Scaling down semiconductor lasers in all three dimensions holds the key to the
development of compact, low-threshold, and ultrafast coherent light sources, as well as …

We present lasing in optically pumped high-Q micropillar cavity lasers with low thresholds
and high β factors. The micropillar cavities with diameters between 1.0 and 4.0 μ m contain a …

We report on low threshold lasing in electrically pumped quantum dot-micropillar cavities.
Lasing action associated with threshold currents as low as 8 μ A at 10 K is observed for …

We report on pronounced magneto-optical effects of spatially confined polariton modes in an
InGaAs quantum-well microcavity. The polaritons were trapped by a lithographically …

An erbium-doped whisper gallery mode microlaser is presented, which consists of an
erbium-doped microsphere placed in an optical fiber open microcavity. The erbium-doped …

We study the possibility of utilizing the superfluid to Mott-insulator quantum phase transition
in an array of quantum well exciton–polariton traps to generate indistinguishable single …

We discuss approaches to increase the light outcoupling efficiency in organic microcavity
(MC) lasers and organic light-emitting diodes (OLEDs). We find that the introduction of …

We report on the optical mode structure of laterally confined organic microcavities. For
preparation, an organic semiconductor is evaporated through a mask with square sized …

Next-generation information technology is expected to rely on discrete two-state quantum
systems that can deterministically emit single photons. Quantum dots are mesoscopic (∼ …

Using time-resolved photoluminescence spectroscopy, we have studied the Purcell
spontaneous emission enhancement provided by a novel type of microcavity that forms a …
