Micropillar cavities are potential candidates for high-efficiency single-photon sources and are testbeds for cavity quantum electrodynamics experiments. In both applications a high quality (Q) factor is desired. It was recently shown that the Q of high-Q semiconductor micropillar cavities exhibit pronounced quasi-periodic variations in the regime from 1 to 4 μm, and a detailed understanding of the...Show More
We report on laser emission from high quality quantum dot micropillar cavities. In these structures cavity quantum electrodynamics (cQED) effects are exploited to realize high efficient, low threshold lasing. We demonstrate that cQED effects allow for the observation of low threshold laser emission from a low number of InGaAs quantum dots embedded in optically and electrically pumped high-Q microp...Show More
Laser emission from a low number of InGaAs quantum dots embedded in optically and electrically pumped high-Q micropillar laser structures will be presented. The talk will focus on the demonstration of high-β low threshold lasing with threshold currents below 10µA and single quantum dot controlled gain modulation under optical excitation.Show More
Heterodyne spectral interferometry is employed to perform four-wave mixing spectroscopy on a strongly-coupled system of an exciton confined in a single quantum dot and a photon mode of a pillar microcavity. The coherent dynamics of one and two photon states are directly observed and the validity of the Jaynes-Cummings model is tested.Show More
We report on a scalable process to incorporate InAs quantum dots in spatially resonant devices. This process combines site controlled quantum dot growth with an accurate alignment of the device to the single QDs.Show More
High quality semiconductor microcavities have attracted considerable attention as a compact solid state platform for the investigation of light-matter interaction between photons and excitons in single quantum dots. Owing to a combined optimization of the design (increased number of mirror pairs), the growth conditions (V/III ratio) and the dry etching process we were able to achieve record qualit...Show More
