The spectroscopy of single InAs/InP quantum dots emitting close to 1.55 μm is described. The dots are produced using a nanotemplate deposition technique that allows precise, a priori control of quantum dot position and electronic configuration. The experimentally observed luminescence signal from the p-shell is composed of several lines. Using exact diagonalization calculations of the emission spectra we interpret the splittings between these lines in terms of Coulomb induced, many-body renormalization of the excitonic states and a template-induced shape asymmetry of the quantum dot.
