Abstract

We present an experimental and theoretical investigation of coupling between two identical GaAs/AlGaAs quantum wells separated by a narrow AlGaAs barrier. The optical properties of this heterostructure were characterized with photoluminescence (PL), time resolved PL, and PL excitation spectroscopies with and without the application of electric fields and other external perturbations. Experimental results for level splittings and Stark shifts agreed well with calculations derived from a simple model.
