David W Stowe, Paul W Fitzgerald, Frederick J Gillham: Miniature fiberoptic bend device and method. Aster Corporation, Fish & Richardson, August 11, 1992: US05138676 (69 worldwide citation)

Bends in optical fibers can be miniaturized by reducing the diameter of a section of the fiber in the region where bending is desired to a condition in which the optical properties of the fiber have reduced bend-loss sensitivity. In one aspect of the invention, radii of curvature less than 100 micro ...
