ABSTRACT:
A coupler device for use with light conducting fibers to couple-out and couple-in a light signal to the fibers comprises at least three optical fibers and a physical structure for holding the fibers in a plane with the first and second fibers converging together to have a portion of each of the fibers adjacent the end faces extending in parallel side-by-side relationship with the end faces being flush and the end face of the third fiber being positioned in abutting relationship against the end faces of the first and second fibers. In one embodiment, the amount of offset between the third fiber and the pair of first and second fibers is adjustable so that the coupler can be changed from a direct coupler of one of the first and second fibers being directly coupled to the third fiber to a branching coupler with the third fiber being connected to both the first and second fibers.
