Abstract
The antisymmetric coupled-quantum-well structure has been used to greatly enhance the blue Stark shift of the heavy-hole-to-electron excitonic transition. This antisymmetric CQW structure can lead to the development of novel optoelectronic devices based on the quantum confined Stark effect. Furthermore, the assumption of the InGaAs/InP/InAsP material system is not essential in this calculation; any quantum-well system that can be designed to form an antisymmetric quantum-well structure will give a large blue Stark shift.
