OPTICALLY-CONTROLLED SWITCH OF MILLIMETER RANGE WITH BUILT-IN LIGHT SOURCE, BASED ON TRANSMISSION LINE WITH SEMICONDUCTOR SUBSTRATE Russian patent published in 2020 - IPC H01L31/09 H01S5/125 

FIELD: radio equipment.

SUBSTANCE: optically-controlled switch comprises bottom-up: substrate made of semiconductor material, which in the absence of an external action acts as a dielectric, a first conductive layer of the transmission line made of a conductive material on the upper side of the substrate, and a laser. Laser comprises an upward bottom: a lower distributed Bragg reflector (DBR) of the laser, which is partially translucent to enable laser light emitting through the lower DBR, an active laser region, and a completely reflecting upper DBR laser. In the substrate, in the beam falling zone, there is a photoconductive portion which, when illuminated with light, is in a conductor state, and in the absence of light is in a dielectric state, in the first conductive layer of the transmission line in the beam incidence region, at least one radiation window is made to allow the laser light to pass to the photoconductive region.

EFFECT: technical result consists in enabling reduction of introduced losses, reduction of power consumption, improvement of isolation between ON / OFF states, increase in switching speed, increase of operating frequency band, reduction of dimensions.
