SURFACE ACOUSTIC WAVES INTENSITY MODULATOR BASED ON A SEMICONDUCTOR QUANTUM WELL Russian patent published in 2022 - IPC H03C1/46 

FIELD: acoustic waves.

SUBSTANCE: invention is intended to modulate the intensity of surface acoustic waves (SAW). The substance of the invention lies in the fact that the intensity modulator of surface acoustic waves contains a base element based on the layered structure LiNbO₃ - SiO_x - InSb - SiO_x, while the physical basis for modulating the intensity of surface acoustic waves is the hopping mechanism of AC conduction in a thin InSb film, which represents a semiconductor quantum well with an impurity band.

EFFECT: providing the possibility of SAW intensity modulation to create an acousto-optical delay line of electrical signals.
