英文摘要	An optical procedure and system for aligning a beam of light to an optical fiber is described. The beam may originate from a diode laser, a light emitting diode, a collimated laser, or an optical fiber. The system controls as many as eight degrees of freedom of the beam incident upon the fiber. The system employs optical leverage to relax assembly tolerances while still achieving the necessary fine tolerances for singlemode fibers. The adjustments are achieved by translation of components along a single direction across the optical axis and along a flat planar base on which the elements are mounted. The optical leverage, the single direction of translation, and the flat-base interface are features that facilitate automated assembly of fiberoptic packages. Planar graded index of refraction lenses are used in a preferred embodiment that enhances the optical coupling efficiency by practically eliminating the reflections at component interfaces.
