UNIMODE FIBRE-OPTIC LIGHT CONDUCTOR FOR POLARIZATION MODE FILTER Russian patent published in 1995 - IPC

Abstract RU 2040493 C1

FIELD: fibre optics. SUBSTANCE: single-mode fibre-optic light conductor for polarization mode filter uses a light-conductivity bundle, two loading round needles. The loading needles are located an both sides of the light-conducting bundle and produce mechanical stresses in it. The light conductor has an external plane-shaped protective shell. The reflecting shell is made of material having an index of refraction lower than that of the protective shell by 2-5·10-3, and diameter equal to 2-3 Db, where Db is the diameter of the light-conducting bundle. EFFECT: improved design. 3 dwg
