TL;DR: In this paper, a brief overview of the current status and recent results of quantum-dash lasers are reported, including topics like dash formation and material growth, device performance of lasers and optical amplifiers, static and dynamic properties and fundamental material and device modelling.

TL;DR: The results confirm the predicted “n factorial” dependence, showing that the tendency to bunch gets stronger as the number of independent photons is increased, and show bunching behavior in the strong coupling case, which vanishes in the weak coupling regime as the cavity starts lasing.

TL;DR: It is shown that the coherent interaction between microcavity polaritons and externally stimulated acoustic phonons forms a tunable polariton superlattice with a folded energy dispersion determined by the phonon population and wavelength.

TL;DR: In this paper, an overview of slow-and fast-light effects in semiconductor active waveguides is presented, emphasizing the physics of these phenomena and the limitations imposed by the carrier dynamical processes.

TL;DR: In this article, theoretical and experimental results on the propagation of ultrashort pulses in quantum-dot (QD) laser amplifiers are presented, where the propagation time of the light pulses is controlled by the pulse itself (self-induced speed control) or by injection of a second pump pulse (external speed control).
