ABSTRACT:
A quantum confined Stark effect (QCSE) optical modulator element has one or more quantum wells each bounded by assymetric barriers. This provides a device in which the direction and magnitude of the electric field induced absorption edge shift corresponds to the polarity and intensity of an applied electric field.
