ABSTRACT:
A fiber optic coupler and method of manufacture of same in which a single core optical fiber is twisted about a dual core optical fiber and is heated to softening while drawing the melted junction out to form a biconical taper for providing a controlled splitting ratio for light from the single optical fiber into the dual core fiber. In another embodiment two single core fibers are fused to form a dual core fiber without coupling between the cores.
