Abstract
Official abstract text for this publication.
There is provided a multi-core fiber that can reduce both skew and crosstalk between cores. The multi-core fiber includes a plurality of cores extending along a fiber axis, and optical claddings surrounding the plurality of cores. The skew between optical signals propagating through the plurality of cores is 1 ps/m or less, and the propagation constant difference between two adjacent cores of the plurality of cores is more than 0.
First claim
Opening claim text (preview).
What is claimed is: 1. A multi-core fiber comprising: a plurality of cores extending along a fiber axis, each of the plurality of cores having a refractive index difference Δn and a diameter 2 a ; and optical claddings surrounding the plurality of cores, and having a core structure change parameter Δ(Δn)/Δ( 2 a ) being out of a range of −3.6×10 −2 to −2.8×10 −2 , wherein Δ(Δn) representing a change amount of the refractive index difference between the cores and is expre…
