In this paper we describe the results of temperature dependent photoluminescence intensity and decay time measurements on a series of InAs/AlGaAs quantum dot structures where the depth of the confinement potential is varied from sample to sample. By comparison with a simple theoretical model the tem
We present measurements of the optical dipole of interband transitions in InAs=GaAs quantum dots. Both the transmission in guided-wave geometry and the in-plane polarization dependence of the photoluminescence are analyzed. The relative oscillator strength and polarization of up to four optical tran
The spin dynamics in self-organized InAs/GaAs quantum dots have been studied by time-resolved photoluminescence performed under strictly resonant excitation conditions. It is demonstrated that the carrier spins in these nanostructures are totally frozen on the scale of the exciton lifetime.
