PHOTONIC FIBER-OPTIC MODULE Russian patent published in 2020 - IPC H01L31/10 

FIELD: radio-photonics.

SUBSTANCE: photonic fiber-optic module includes a laser source of optical signal of microwave pulses, two assemblies of in-series connected microwave photodetectors and three optical splitters, secondary optical fibers of the first optical splitter are optically coupled with series-connected photodetectors of the first assembly of photodetectors, secondary optical fibers of the second optical splitter are optically coupled with series-connected photodetectors of the second assembly of photodetectors, both assemblies of photodetectors form parallel counter connection, and connection points of assemblies of photodetectors are connected through microwave channel to antenna, primary fiber of third splitter (1×2) is optically connected to laser source of optical signal of microwave pulses, and secondary two optical fibers of third splitter have different length and are optically connected to primary optical fibers of first and second optical splitters.

EFFECT: higher efficiency of antenna.
