When the n=1 (ground) state of quantum dots is resonantly pumped, a "non-degenerate" biexciton composed of an n=1 and n=2(excited) states-pair may be observed with pump-probe spectroscopy. We observed this resonance and measured 15-meV binding energy in In0.4Ga 0.6As self-organized quantum dots, consistent with theoretical calculations.
