Carrier cooling is measured in an Al0.48In0.52As/Ga0.47In0.53As/InP heterostructure by time-resolved photoluminescence experiments for excitation densities between 5×1016 and 2.2×1018 cm−3. For low excitation density, the energy-loss rate by emission of optical phonons is close to theoretical bulk value, whereas a reduction of the energy-loss rate by a factor of 100 is found for the highest excitation density.
