SINGLE-MODE OPTICAL WAVEGUIDE WITH LARGE EFFECTIVE AREA ( VERSIONS ) Russian patent published in 2001 - IPC

Abstract RU 2166782 C2

FIELD: radio engineering. SUBSTANCE: single-mode optical waveguide with large effective area has decreased nonlinear effects in working window on wave lengths 1300 and 1550 nm. Examples of profiles of refractive index of region of core which ensure required characteristics is improved profile with stepped change of refractive index and profiles having maximum Δ% at distance from central axis of fiber. EFFECT: improved functional characteristics of waveguide. 10 cl, 4 dwg, 2 tbl
