We observed exciton and biexciton states in a single GaAs quantum dot at 4 K using micro pho-toluminescence system and investigated power dependent photoluminescence measurements to identify both exciton and biexciton states. The biexciton and exciton states showed quadratic (a~2.2) and linear (a~0.95) increasing power factor, respectively. The large energy difference (~0.2 meV) from exciton states for the perpendicular polarization was observed.
