  • Few mode optical fibers
    Patent number: 8971682
    Abstract: A few mode optical fiber comprising: a Ge-free core having an effective area Aeff of LP01 mode wherein 120 ?m2<Aeff<1000 ?m2 at 1550 nm, and a refractive index profile selected such that the core is capable of supporting the propagation and transmission of an optical signal with X number of LP modes at 1550 nm, X is an integer and 1<X?20, maximum refractive index delta of the core, ?0, wherein ?0.5%??0?0.08%; and, an annular cladding surrounding the core having a low index ring with a minimum refractive index delta ?rMIN, ?rMIN<?0 and ?rMIN??0.3 relative to pure SiO2, an outer cladding with a refractive index delta ?Outer-Clad, such that ?Outer-Clad>?rMIN; and |?0??Outer-Clad|>0.05%, the relative refractive index profile of the optical fiber is selected to provide attenuation of <0.18 dB/km at the 1550 nm, and LP11 cut off wavelength >1600 nm.
