摘要： Provided is an optical coupler, which can allow the light to be branched off by the required amount when necessary, and a method of branching light using the optical coupler. Optical coupler 1 has optical fiber 10 that has small-diameter part 12, which is formed so as to have a relatively small outer diameter at a portion in the longitudinal direction, and that branches off the transmitted light by small-diameter part 12; and output optical fiber 20 that receives the light branched off from input optical fiber 10. Small-diameter part 12 of input optical fiber 10 is caused to contact with linear small-diameter part 22 of output optical fiber 20; a coupling length, which is the length along which small-diameter part 12 of input optical fiber 10 and small-diameter part 22 of output optical fiber 20 are made to contact with each other, or a propagation constant of the optical fibers is varied; and thus, branching ratio S of the light branched off from input optical fiber 10 into output optical fiber 20 is varied.
