Patent ID: 6868206

Claim:
A method of manufacturing an optical device comprising: providing a fiber array comprising regularly-spaced optical fibers such that an output axis of each optical fiber has a predetermined spatial position and orientation with respect to a reference edge of the fiber array; providing an array of lenses and a mirror array, the mirror array positioned at a beam waist line for the array of lenses, the array of lenses mounted between the fiber array and the mirror array, such that the array of lenses may be adjusted with at least five degrees of freedom; identifying a baseline position alignment position for the array of lenses; aligning the fiber array with the array of lenses at an alignment position such that collimated light from each lens has a predetermined position and direction with respect to the reference edge, the array of lenses being separated from the fiber array by a gap; and coupling the fiber array to the lens array at the alignment position.
