Fiber lens with multimode pigtail

摘要

A fiber lens includes a multimode fiber and a refractive lens disposed at an end of the multimode fiber. The refractive lens focuses a beam from the multimode fiber into a diffraction-limited spot. In one embodiment, a graded-index is interposed between the multimode fiber and the refractive lens. In one embodiment, the combination of the graded-index and the refractive lens enables extreme anamorphic lens characteristics.
