Abstract
Systems are described for coupling a pair of optical fibers to pass light between them, which enables a coupler to be easily made, and with simple equipment, while closely controlling the characteristics of the coupler. One method includes mounting a pair of optical fibers (12A, 14A) on a block (26) having a large hole (28) therein, so the fibers extend across the hole while lying adjacent and parallel to one another. The fibers are immersed in an etchant (40) to reduce the thickness of cladding (20) around the fiber core (18). The fibers are joined together by applying a liquid polymer (16, FIG. 6) so the polymer-air interface moves along the length of the fibers to bring the fibers together in a zipper-like manner, and to progressively lay a thin coating of the polymer on the fibers.
