OPTICAL ELEMENT Russian patent published in 2003 - IPC

FIELD: fiber-optical communication lines. SUBSTANCE: optical element includes fiber-optical waveguide and branch made of clear material. Light-tapping section fabricated in sheath of fiber-optical waveguide is utilized in the capacity of branch. Photodiode of photodetector with controlled gain is arranged directly across output of light-tapping section. Fiber-optical waveguide can be fixed on solid backing. At least one more light-tapping section can be arranged over length of fiber-optical waveguide. Each photodiode is provided with individual amplifier. EFFECT: provision for effective transmission of light power from one waveguide to another. 3 cl, 1 dwg
