抄録

Recent development of micro-photoluminescence spectroscopy has enabled the authors to observe photoluminescence from a single quantum dot, which has sharp homogeneous linewidth and long coherence time. In this paper, the authors report on the micro-photoluminescence spectra of single GaAs/AlGaAs quantum dots grown on a (411)A surface of a GaAs substrate. They have also observed sharp luminescence lines originating not only from the lowest state of the confined exciton, but also from the excited states depending on the excitation power density.
