TL;DR: In this paper, site-controlled In(Ga)As quantum dots (QD) were grown by molecular beam epitaxy on pre-patterned GaAs (001) substrates and integrated into optical resonators.

TL;DR: In this paper, the first autocorrelator based on two separated detectors integrated on top of the same ridge waveguide was presented, achieving an efficiency of 1% at 1300 nm for both detectors and independent of the polarization of the incoming photons.

TL;DR: In this paper, cavity quantum electrodynamics studies in optically and electrically pumped quantum dot micropillar systems are reported, and light-matter interaction effects in the quantum limit and possible applications in efficient light sources are discussed.

TL;DR: Feature selection is an important component of data mining and knowledge discovery process, due to the availability of data with hundreds of variables leading to data with very high dimension as discussed by the authors, which aims at reducing the number of features by removing irrelevant or redundant ones, while trying to reduce computation time, preserve or improve prediction performance.

TL;DR: In this paper, the authors measured time-resolved photoluminescence from large quantum dots near a semiconductor-air interface and found that the results were consistent with dipole theory but near the interface they question the validity of the dipole approximation.
