The most important features of the physics of microcavity-embedded quantum wells are reviewed, with particular attention to the optical properties of exciton polaritons. The strong coupling regime, in which a finite polariton mode splitting appears (also c ...
The interplay of disorder effects and exciton-exciton interactions in the four-wave-mixing process in quantum wells is investigated. Experiments are performed employing femtosecond and picosecond pulses to have either good temporal or good spectral resolut ...
The influence of static disorder on the optical properties of microcavity-embedded quantum wells is studied by means of a microscopic model. Both the exciton-photon coupling and the exciton-disorder interaction are treated nonperturbatively. Despite the no ...
Summary form only given. Radiative coupling between one or more quantum wells (QWs) and the single-cavity mode of a moderate reflectivity semiconductor microcavity leads to normal-mode coupling (NMC), observed as a doubled-peaked spectrum in reflection, tr ...

The initial dynamics of resonantly excited secondary emission from quantum wells are dominated by Rayleigh scattering due to excitons localized in the disordered quantum well potential. We show experimentally and theoretically how the temporal shape of the ...

Chemical beam epitaxy (CBE) grown InAsP/InGaAsP edge-emitting laser diodes on GaAs substrates obtained by localised fusion in a nitrogen environment exhibit high quality fused interfaces. A degradation of fused lasers is observed which is attributed to the ...
We have irradiated by thermal neutrons single crystals of the Bi-2212 high T-c superconductor. The irradiated samples are insulators, but they regain high T-c superconductivity after an annealing in He at 450-550 degrees C. Depending on irradiation doses a ...
The 2-K recombination dynamics of coupled GaN-AlGaN multiple quantum wells reveals a composite nature in terms of the joint contributions of short-lived direct excitons and long-lived oblique ones. The possibility to observe these oblique excitons, which p ...
Polaritons in confined systems are introduced and their dispersion is calculated. The amount of squeezing of confined excitons polaritons in GaAs quantum wells is evaluated. ...
GaAs/AlxGa1-xAs multiple-quantum-well (MQW) structures with identical well thicknesses but with different Al contents x in the barrier (x almost-equal-to 0.1, 0.2, 0.45, and 1) were grown by molecular-beam epitaxy to study the impurity-induced disordering ...
