| Abstract(in English) | It has been made clear that lensed fibers with specific configurations are suitable for coupling from LD's that have narrow divergence. Two schemes of the lensed fiber are considered. One consists of a hemispherically-ended coreless-fiber and a quarter-pitch length of graded-index fiber, the other consists of a hemispherically-ended quarter-pitch length of graded-index fiber. We have demonstrated performance of the lensed fiber theoretically and experimentally. Coupling experiments between the LD and a flat-end SMF are also shown for the comparison. We confirmed that the lensed-fiber coupling scheme has features, such as low coupling losses, a long working distance, a low light reflection, and a large tolerance. |
