Exciton-based devices have been shown to display remarkable properties that can find applications in optical information processing. However, if these devices are to be used in systems where many devices and chips involving the excitonic effect are to be used, there has to be stringent control over the quantum-well perfection. In this paper we examine the effect of exciton linewidth and well size fluctuations on a number of device-related effects based on the quantum-confined Stark effect. We find that for many applications a one-monolayer variation in structures fabricated in different runs will drastically diminish the system performance
