Abstract
Official abstract text for this publication.
A multicore fiber includes cores located at vertexes of a polygonal ring and a cladding including sub medium regions and covering the cores. A refractive index of the cladding is lower than a refractive index of the cores and higher than a refractive index of the sub medium regions. The sub medium regions are arranged at positions to reduce a crosstalk between adjacent cores of the cores.
First claim
Opening claim text (preview).
What is claimed is: 1. A multicore fiber comprising: cores located at vertexes of a polygonal ring; and a cladding including sub medium regions and covering the cores, a refractive index of the cladding being lower than a refractive index of the cores and higher than a refractive index of the sub medium regions; wherein the sub medium regions are arranged at positions to reduce a crosstalk between adjacent cores of the cores, wherein a shape of each of the sub medium regions is an ellipse that crosses a first line segment linking the adjacent cores, and wherein a longitudinal direction of the ellipse crosses a direction of the first line segment. 2. The multicore fiber according to claim 1 , wherein no core is included inside the polygonal ring. 3. The multicore fiber according to claim 1 , wherein the cores comprise first cores having a first optical characteristic and second cores having a second optical characteristic which is different from the first optical characteristic, wherein the first cores and the second cores are located on the vertexes of the polygonal ring alternately.
