We report the first observations of quantum size effects in GaAs/GaAs0.5P0.5 strained‐layer superlattices (SLS’s). Using excitation and photoluminescence spectroscopies, we have observed optical transitions between excited states of the electron and hole quantum wells. These observations provide a measure of the biaxial compressive strain in the GaAs layers, interfacial roughness, and valence‐band offset for the GaAs/GaP heterojunction.
