OPTICAL CONNECTION MEMBER, OPTICAL CONNECTION STRUCTURE, AND METHOD FOR PRODUCING OPTICAL CONNECTION MEMBER

摘要

An optical connecting member 1 realizes an optical connecting between a multi-core fiber 2 and a plurality of single-core fibers 3 by a waveguide part 12 which connects a first end face 13a and a second end face 14a. With the optical connecting member 1, a connected end 12 A which is connected to the first end face 13a is a straight-line portion that is orthogonal to the first end face 13a in each of the plurality of waveguide parts 12. In addition, a diverged end 12B which is diverged to the second end face 14a is a straight-line portion that is orthogonal to the second end face 14a. Consequently, light that has passed through the waveguide parts 12 is emitted from the first end face 13a and the second end face 14a substantially perpendicularly to the faces 13a, 14a, thereby enabling optical connecting loss to be favorably inhibited.
