ABSTRACT:
A low-cost, high performance 1.times.N fiber optic coupler where N>16 is presented. The coupler has a GRIN lens having an first optic fiber aligned with the optical axis of the lens at one end of the lens. The first optic fiber ends in a microlens. At the other end of the GRIN lens a bundle of tapered second optic fibers is centered on the optical axis of the lens. The microlens is formed by fusing two fibers together, stretching the fused region, jerking the fibers apart and then heating a fiber end to form the lens.
