Optical transitions in self‐assembled InAs/AlAs quantum dots were investigated by photoluminescence and photoluminescence excitation spectroscopy. In photoluminescence we found below about 1.8 eV emission from quantum dots whereas above ∼1.8 eV electrons from the AlAs X‐band are involved. Photoluminescence excitation spectra show polaron states with a phonon energy of 31 meV of an individual InAs dot.
