Samenvatting

We observe an anomalous exciton lifetime in columnar InAs/GaAs quantum rods by using the time-resolved differential reflectivity (TRDR) technique. At low excitation d., the decay time of the TRDR signal show a clear excitonic type of behavior. At increased excitation, a resonant radiative lifetime develops, which seems to be dependent on the excited QD d. being resonant with the probe laser spectrum. We interpret the resonance behavior as due to electromagnetic coupling between the excited QDs resonant with the probe laser.
