We describe near-field photoluminescence imaging spectroscopy of a single naturally occurring GaAs quantum dot in a narrow quantum well. A spatial mapping of the center-of-mass wave function of the exciton state in the quantum dot is demonstrated due to the realization of a high spatial resolution (30 nm) of imaging spectroscopy and the selection of a large quantum dot (100 nm). We observe an elongation along the [110] crystal axis of the wave function in the exciton state.
