Abstract
We demonstrate electrically controlled photocurrent (absorption) tristability in an asymmetric coupled quantum well p-i-n diode connected to a series resistive load. The phenomenon, which is explained in terms of a self-electro-optic effect, is brought about by making use of an anticrossing behavior of excitonic optical transitions instead of the usual quantum-confined Stark effect.Keywords
