    摘要： An optical fiber includes a silica-based glass portion having an outer diameter of less than about 120 μm. The glass portion comprises a core, an inner cladding and a low index ring. The core comprises an index of refraction n1, and a relative refractive index percent Δ1% relative to pure silica glass. The inner cladding surrounds the core and comprises an index of refraction n2, a radial thickness of less than about 40 μm and a relative refractive index percent Δ2% relative to pure silica glass, wherein Δ1%>Δ2% and the difference between Δ1% and Δ2% is greater than 0.1%. The low index ring surrounds the inner cladding and comprises boron and fluorine, a radial thickness of less than about 20 μm, an index of refraction n3 and a third relative refractive index percent Δ3% relative to pure silica glass, wherein Δ2%>Δ3% and Δ3% is less than −0.5%.

    摘要： A method for producing an optical fiber is provided. The method includes the steps of drawing an optical fiber from a heated glass source in a furnace and introducing index perturbations to the optical fiber via a plurality of perturbation sources arranged at a plurality of different azimuthal locations. The index perturbations are introduced synchronously at different locations along the axial length of the fiber by the plurality of perturbation sources in a generally helical pattern on the outside surface of the fiber in one embodiment. According to another embodiment, the index perturbations are introduced by the plurality of perturbation sources at different frequencies.
