Abstract Single InAs/GaAs quantum dots are studied using micro-photoluminescence
spectroscopy. Single dot spectroscopy shows an antibinding biexciton. Some of these
quantum dots are laterally coupled due to an anisotropic dot repartition. At low excitation
power density, four excitons emissions are observed and are interpreted as the four possible
exciton recombinations of two coupled quantum dots.(© 2006 WILEY-VCH Verlag GmbH &
