We use photoluminescence spectroscopy to investigate the ground state of single self-assembled InGaAs lateral
quantum dot molecules. We apply a voltage along the growth direction that allows us to control the total charge
occupancy of the quantum dot molecule. Using a combination of computational modeling and experimental
analysis, we assign the observed discrete spectral lines to specific charge distributions. We explain the dynamic
processes that lead to these charge configurations through electrical injection and optical generation. Our systemic
analysis provides evidence of interdot tunneling of electrons as predicted in previous theoretical work.
