OPTIC-ELECTRONIC DEVICE Russian patent published in 2006 - IPC H03B17/00 G01J11/00 

FIELD: optical electronics, in particular, engineering of devices for transforming pulse optical emission to pulse electric signal of appropriate duration and shape, possible utilization for generating single or series of ultra-short electric pulses, registration of optical radiation pulse shape, measuring power of optical radiation.

SUBSTANCE: optic-electronic device for generation of ultra-short electric pulses and registration of shape of optical radiation pulses has light source of ultra-short pulses, transformer of light to electric signal, two electrodes positioned on the surface of light transformer and having electrical contact with same. Light transformer is made in form of film of carbon material having optical rectification property. Surface of film is positioned in inclined manner relatively to falling beam from light source. Optic-electronic device additionally includes device for measuring amplitude, shape and duration of electric voltage pulses. Light transformer may be realized in form of film, applied to substrate with electric conductivity being substantially lower than electric conductivity of film material. Electrodes can be made in form of linear electric conductors, positioned in parallel to each other and perpendicularly to light falling plane, in particular between carbon film and substrate. Also possible is adding of optical device to device for transformation of ultra-short pulse source to linearly polarized radiation in plane, perpendicular to film plane, and positioned between light source and light transformer, and beam expander, positioned between ultra-short pulse source and light transformer.

EFFECT: simplified construction of device, improved transformation efficiency.
