Abstract
A quantum well wave modulator comprises a central well sandwiched by two lateral wells. The central well is populated with electrons and the two lateral wells, having different constitutions, are coupled to the central well so as to modulate two light waves under the effect of the application of an electrical field perpendicularly to the structure in one direction or in the opposite direction.
