OPTICAL MICROWAVE PULSE GENERATOR Russian patent published in 2010 - IPC H01L31/00 G02F1/15 B82B1/00 

FIELD: physics.

SUBSTANCE: invention can be used in different-purpose information processing systems for optical generator and control of space-time characteristics of a microwave signal. The optical microwave generator consists of a ν-layer of high-resistance direct band-gap semiconductor crystal with intrinsic conductance 1, to similar nanosized dielectric monolayers 2 lying symmetrically about the ν-layer 1 between the ν-layer and optically transparent electrodes 3, two antireflection coatings 4, made on the surface of the optically transparent electrodes 3, two dielectric guard rings 5, each encircling the nanosized dielectric monolayer 4, optically transparent electrode 3 and antireflection coating 4. The optically transparent electrodes 3 are connected through electric contacts 6 to a bias voltage source 7, and a recording device 9 is connected through a load resistor 8 to bias voltage source 7 and one of the electric contacts 6. The axis of radiation 14 of the control light source 10 is formed by an optical system 11 and is perpendicular to the plane of the antireflection coating 4. The axis of radiation 15 of a second control light source 12 is formed by an optical system 13 and is perpendicular to the plane of the second antireflection coating 4.

EFFECT: design of an optical microwave generator of photoelectric current pulses, which enables generation of microwave pulses only due to illumination, optical and electrical control of parametres of generated oscillations during different generation modes, and increase frequency of optically generated oscillations.
