Abstract
A wideband single-mode fiber optic coupler and method for the fabrication of the same is provided wherein at least two fibers are joined in a fused and tapered coupling region. The taper is asymmetrical in the longitudinal extent about the midpoint of the geometric center of the fused coupling region with the difference between the fiber diameters in that region changing at a varying rate along the length of the region.
