Abstract
Optical transitions associated with the electronic levels of a single quantum well in GaAs/AlxGa1−xAs heterostructures are observed with exceptional clarity in the piezomodulated reflectivity spectrum measured down to liquid helium temperature. The splitting of such transitions in multiple quantum well structures due to the coupling of the electronic levels in the adjacent wells is illustrated with results on a double quantum well.Keywords
