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.
其他摘要	描述了一种用于将光束对准光纤的光学过程和系统。光束可以源自二极管激光器，发光二极管，准直激光器或光纤。该系统控制入射到光纤上的光束的多达八个自由度。该系统采用光学杠杆作用来放松装配公差，同时仍能实现单模光纤的必要精细公差。通过沿光轴的单个方向并沿着安装有元件的平坦平面基座平移元件来实现调节。光学杠杆，单一平移方向和平底接口是促进光纤封装自动组装的特征。平面渐变折射率透镜用于优选实施例中，其通过实际消除部件界面处的反射来增强光学耦合效率。
主权项	A compound lens arranged to intersect a beam of light, the beam of light having a first beam and a second beam, both of which are external to the compound lens, wherein the first beam has an absolute convergence less than or equal to the absolute convergence of the second beam, the compound lens comprising: a first one-axis lens that defines a first axis of focus oriented at a first radial angle, the first one-axis lens adjacent to the first beam, a second one-axis lens that defines a second axis of focus oriented at a second radial angle, wherein the first and the second radial angles are not equal or opposite to each other, the second one-axis lens adjacent to the first one-axis lens and optically coupled to the first one-axis lens, and the second one-axis lens adjacent to the second beam, and means for translating the first one-axis lens and the second one axis lens, independently, each along a single translation direction that defines a third radial angle, wherein the third radial angle is not equal or opposite to either of the first or the second radial angles.
