Abstract
We report the experimental realization of asymmetric stepped InGaAs/In GaAsP quantum wells. The structure was designed to optimize the quantu m-confined Stark shift. We have observed a shift of 30 meV in the heav y hole exciton absorption peak over an electric field change of 50 kV/ cm. This shift is double that observed for the same structure without the stepped wells.
