摘要
自聚焦透镜与多模光纤的折射率分布都遵从平方律分布 ,基于这个事实 ,进行了以多模光纤生产工艺制造微型准直透镜的研究和设计。结果表明 ,该微型准直透镜用作单模光纤准直器 ,具有良好的准直性能 ,该器件较之自聚焦透镜 。
The refractive index profile of gradient index (GRIN) lens obeys square rule,as same as multimode fiber. Based on this fact,the research and design of micro align lens which is fabricated by means of multimode fiber fabrication techniques is carried out. Results show that the micro align lens has good performance as single mode fiber(SMF) collimator.Compared with GRIN lens,it has smaller size and can be fabricated simply.
