The magnetoluminescence of InAs/GaAs self-assembled quantum dots (QDs) is studied. Using different excitation intensities, the dots are filled with up to 11–12 electron-hole pairs and the magnetic field evolution of the excited-state emissions is revealed. The magnetoluminescence spectra resemble very well the spectra of uncorrelated electro-hole pairs. A splitting of the states with a nonzero angular momentum quantum number is observed and the in-plane reduced electron-hole mass is determined. The experimental value is found to be in a good agreement with the theoretical predictions based on the eight-band $\mbi{k \cdot p}$ model including both strain effect and band nonparabolicity.
