ABSTRACT:
An optically controlled light modulator device, consisting of a semiconductor heterostructure with at least one quantum well layer and two strained barrier layers. The device is capable of modulating a first beam ("read" beam), through the Quantum Confined Stark Effect and the influence of a perpendicular electric field, produced all-optically by electrons and holes which are generated by the absorption, either of the first beam itself or of a second beam ("control" beam), and which are separated in opposite directions by the piezoelectric field of the barrier layers.
