ABSTRACT:
The present invention relates to a fused-fiber optical coupler, and method of forming the same, which does not require a tapering of the fibers. A two-step fusion process is utilized where initially the end sections of the plurality (N) of output fibers are fused together to create a bullet-shaped end section. The bullet-shaped end section is then butt-coupled and fused to the input fiber (or M input fibers) to form a 1.times.N (or M.times.N) fiber coupler.
