TL;DR: In this article, a Bragg reflector AlAs/GaAs planar cavities with a low density In 0.3 Ga 0.6 As quantum dot layer by molecular beam epitaxy were constructed using electron beam lithography and deep plasma etching.

TL;DR: In this paper, the authors investigated the group delay and the dispersion of light propagating through photonic crystal (PhC) resonators defined in 240 nm thick GaAs membranes.

TL;DR: In this article, a magneto-optical investigation of large elongated single self assembled In 0.3 Ga 0.7 As quantum dots with a low surface density of 3 × 10 9 cm -2.

TL;DR: In this article, an experimental system that allows one to easily access the dispersion curve of exciton-polaritons in a microcavity is described. But this system is based on two spatial light modulators (SLM), one for changing the excitation angles (momenta), and the other for tuning excitation wavelength.

TL;DR: In this article, the probability of a laterally correlated growth is strongly enhanced with decreasing spacer layer thickness, but no measurable variation of both the size and the average In alloy concentration of the quantum dots within the stacks is found, making the structures ideally suited for potential applications in quantum information processing.
