A first optical fiber is coupled to a second optical fiber by ablating a portion of the cladding from the first and second optical fibers, thus exposing or nearly exposing the fibers' cores, bringing the ablated regions close together in the presence of an optical couplant, adjusting the alignment of the fibers so as to achieve a desired optical coupling ratio, and securing the fibers relative to each other. The ablation can be accomplished using a laser. The fibers can be secured mechanically or using adhesives. The finished coupler can be sleeved or otherwise encapsulated for physical protection. The technique can be applied to pairs of fiber ribbons, each having multiple optical fibers.
