METHOD FOR GENERATING LIGHT BEAMS FOR OPEN OPTICAL COMMUNICATION SYSTEMS

摘要

FIELD: optical communication systems; two- way data transmission. SUBSTANCE: modulated non-monochromatic light beam is passed through optical fiber followed by its concentration with aid of optical antenna; in the process light beam is shaped with frequency spectrum width DeltaV and angular spectrum width Deltatheta exceeding diffraction angle corresponding to optical fiber diameter; beam is modulated by signal with frequency band deltaV and converted into several optical-fiber modes at maximal difference in speeds between them. EFFECT: reduced speckle-structure of light field generated. 4 cl, 1 dwg, 3 ex
