Abstract

Optical fibers having a given numerical aperture may be efficiently coupled to optical fibers having a different numerical aperture by using a tapered coupling rod or tube which matches numerical apertures. This also permits the lower numerical aperture fibers to be larger in number than the higher numerical aperture fibers.
