FIBER LENS WITH MULTIMODE PIGTAIL

摘要

A fiber lens (100) includes a multimode fiber (104) and a refractive lens (102) disposed at an end of the multimode fiber. The refractive lens (102) focuses a beam from the multimode fiber (104) into a diffraction-limited spot. In one embodiment, a graded-index (fiber) is interposed between the multimode fiber (104) and the refractive lens (102). In one embodiment, the combination of the graded-index (fiber) and the refractive lens enables extreme anamorphic lens characteristics.
