Abstract
Optical fiber combiner includes a plurality of input optical fibers having a core and a cladding surrounding the core, a bridge fiber having a portion that transmits a light beam entered from each of the input optical fibers, and a glass member fusion-spliced to an end face of the cladding and to a first end face of the bridge fiber. The end portions of the claddings of the plurality of input optical fibers are bundled on at least a first end face side, with the adjacent side surfaces of the claddings being in contact with each other. The glass member has an outer diameter greater than the diameter of the core and smaller than the outer diameter of the cladding. The adjacent glass members are in a non-fusion-spliced state.
