摘要 | The present invention relates to a conical wedge-shaped lensed fiber and the method of making the same. The method comprises: (a) providing an optical fiber having a central axis and an end; (b) machining the end of the optical fiber to form a flat end face; (c) machining the end of the optical fiber to form a conical region; (d) machining one side of the conical region to form a flat first surface; (e) machining another side of the conical region to form a flat third surface, wherein the first surface and the third surface intersect at a intersecting line that is perpendicular to the central axis; and (f) fusing the intersecting line to form a lens. The method has simplified fabricating processes and need not to set up any particular angle of rotation of the fiber. Therefore, the fabricating time and cost are reduced, and the coupling efficiency of the lensed fiber is up to 90%. |
其他摘要 | 锥形楔形透镜光纤及其制造方法本发明涉及一种圆锥形楔形透镜光纤及其制造方法。该方法包括:(a)提供具有中心轴和端部的光纤; (b)加工光纤的末端以形成平坦的端面; (c)加工光纤的末端以形成锥形区域; (d)加工锥形区域的一侧以形成平坦的第一表面; (e)加工锥形区域的另一侧以形成平坦的第三表面,其中第一表面和第三表面在垂直于中心轴线的交叉线处相交; (f)融合交叉线以形成镜头。该方法简化了制造过程,并且不需要设置光纤的任何特定旋转角度。因此,减少了制造时间和成本,并且透镜光纤的耦合效率高达90%。 |
