We report on high efficient electrically pumped quantum dot-micropillar single photon sources. The triggered sources show record high efficiency (34%) and single photon emission rates of up to 47 MHz under pulsed electrical excitation.
We report on high efficient electrically pumped quantum dot-micropillar single photon sources. The triggered sources show record high efficiency (34%) and single photon emission rates of up to 35 MHz under pulsed electrical excitation.
The investigation of quantum electrodynamics effects such as weak and strong coupling in quantum dot- micropillar systems in electrically contacted devices has recently become possible due to advances in nano- processing. This is of high interest for practical applications, e.g. the realization of compact single photon sources. Moreover, compared to simple optically excited structures electrically...
Recent progress in the field of electrically pumped single photon sources based on quantum dotmicrocavity systems will be reviewed. We demonstrate efficient single photon emission at rates exceeding 40 MHz from electrically pumped micropillar cavities.
We report on cavity quantum electrodynamics effects in high-Q electrically contacted quantum dot-micropillar cavities. The structures show weak coupling and strong coupling via electrooptical tuning as well as single photon emission and low threshold lasing.
We realized high-quality electrically pumped mircopillar cavities featuring pronounced cQED effects, such as weak coupling and high-beta lasing. The high quality of the electrically contacted micropillars allowed the observation of strong coupling via electro-optical resonance-tuning.
