Abstract
An optical fiber having at least a first central core segment, said central core segment comprising at least a first region having a width no more than 0.2 μm over a core delta % of 0.1 or greater. The first core region may also over a delta height of at least 0.15 delta % exhibits a profile volume less than 0.1. Such core segments can facilitate optical fibers which exhibit an L01 acousto-optic effective area which is greater in magnitude than the L02 acousto optic effective area.

An optical fiber comprising at least a first central core segment, said central core segment comprising at least a first region comprising an inner radius r1 and an outer radius r2 wherein r2−r1 is less than or equal to 0.2 μm at every point over a core delta % of 0.1 or greater when the core delta % at r1 is equal to that at r2;
- wherein the region further comprises peak core delta % at a radius between r1 and r2 and a profile volume of at least 0.030 and no more than 0.17 Δ%-μm2 over a delta height of 0.15.
An optical fiber comprising at least a first central core segment, said central core segment comprising a region at the top of the core segment comprising a region over a delta height of at least 0.15 delta % which exhibits a profile volume less than 0.1 Δ%-μm2, said profile volume calculated between the inner radial and outer radial limits of the core segment, and wherein said optical fiber exhibits an L02 acousto-optic effective area lower than L01 acousto-optic effective area wherein said region exhibits a first alpha and at least one other portion of the core segment exhibits a second alpha and the first alpha is less than 0.5 and said second alpha is greater than 0.5.
An optical fiber comprising at least a first central core segment, said central core segment comprising a region at the top of the core segment comprising a region over a delta height of at least 0.15 delta % which exhibits a profile volume less than 0.1 Δ%-μm2, wherein said region exhibits a first alpha and at least one other portion of the core segment exhibits a second alpha and the first alpha is less than 0.5 and said second alpha is greater than 0.5.
