Disclosed is an optical fiber coupler for multiplexing pumping laser light and signal laser light having ordinary optical fibers on an input side and at least one rare-earth doped optical fiber on an output side. Also disclosed is a method of producing an optical fiber coupler comprising the steps of fusing an ordinary optical fiber and a rare-earth doped optical fiber end to end at a connected section to form a single joint fiber, disposing a pair of single joint fibers in parallel contact with the connected sections thereof aligned, heating to fuse a region of the pair into a fused fiber region, and elongating the heated fused fiber region creating a fused and elongated region to adjust a diameter thereof.
