Abstract

Time-resolved photoluminescence measurements with <5 µm spatial resolution have provided direct evidence of carrier confinement in micrometer-dimensioned GaAs/AlGaAs multiple quantum-well microresonators delineated by alloy mixing. Carriers are confined in individual devices of size 2-50 µm without degradation of lifetime.
