An inter/intra-band double-resonance technique that allows to make an unequivocal assignment of the resonant bound-bound intersublevel absorption in self-organized InAs/GaAs quantum dots is developed. The method is applied to dots grown at a low growth rate, which show well resolved photoluminescence (PL) lines. The double resonance and its polarization selection rules allows the identification not only the levels involved in the PL transition but the relative importance of the causes of its inhomogeneous broadening.
