摘要：
We report the experimental realization of asymmetric stepped InGaAs/InGaAsP quantum wells. The structure was designed to optimize the quantum-confined Stark shift. We have observed a shift of 30 meV in the heavy 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.
