Abstract

We report the low-temperature photoluminescence and its excitation spectra of GaAs/Al_0.32Ga_0.68As Bragg confining structures. The spectra of these structures, which consist of short superlattice sections separated by Al_0.32Ga_0.68As spacer layers, are compared with those of conventional superlattices. The energies of the observed optical transitions between the Bragg confined levels (localization on the spacer layer) are in a good agreement with calculations, based on the Kronig-Penney model for the envelope functions of the electrons and holes.
