Description	Submicron spatial resolution photoluminescence is used to assess radiative efficiency and spatial uniformity of GaAlAs/GaAs heterojunctions. Room temperature photo-luminescence of multiple GaAlAs wells with GaAs barriers was measured as a function of a facet of device perpendicular to the layer structure The scanning near-field optical microscope is applied for the diagnostics of the defects in semiconductor devices for instance in a multiple quantum well grown by molecular beam epitaxy. Our high resoluution studies reveal that the radiative recombination for the GaAlAs quantum well is approx. 50 times more efficient than for the underlying GaAs film. The comparison of the Far-field and Near-field characteristics of measured quantities are also given.
