Title:
MULTICORE FIBER, OPTICAL DEVICE, AND METHOD FOR MANUFACTURING MULTICORE FIBER
Document Type and Number:
WIPO Patent Application WO/2024/034233
Kind Code:
A1
Abstract:
The present invention implements a multicore fiber which makes it possible to easily measure the position of a marker. In an end surface (σ1) of a multicore fiber (MF), a plurality of cores (a1 to an) are disposed line-symmetrically with respect to a virtual axis (L1) orthogonal to an inclination direction (v1) of the end surface (σ1). When the end surface (σ1) is virtually divided into two, a first region and a second region, by the virtual axis (L1), a core farthest from the virtual axis (L1) out of cores (a1, a4) provided in the first region is defined as a first core, and a core farthest from the virtual axis (L1) out of the cores (a2, a3) provided in the second region is defined as a second core, in the end surface (σ1), the center of a marker (c) is included in a region between a straight line passing through the first core or a mode field of the first core and parallel to the virtual axis (L1) and a straight line passing through the second core or a mode field of the second core and parallel to the virtual axis (L1).
