Abstract
A fiber optical array with precision fiber and positioning and a process for manufacturing such an array. The position of the ends of the optical fibers depends upon placement within a target that has been lithographed using highly precise lithography similar to that used in VLSI integrated circuits. The placement of an end with its core within its target is performed with the aid of microscopes and micro-manipulators. Once an end is in the proper location, ultraviolet curable adhesive is used to permanently fix its position precisely. Arrays having positional precision to within 1 micrometer are achievable by this invention.
