摘　　要：论述了GRIN光纤传输特性与自聚焦原理,分析了LD与光纤的耦合特性,介绍了微透镜光纤的结构、高效耦合原理与加工工艺以及技术指标。提出采用GRIN与普通光纤级联,进一步提高耦合效率和失调容差的新思路。The transmission properties and self-focal principle of graded-index （GRIN） fibers are dissertated, the coupling properties of lasers to optical fibers are analyzed, different structures of lensed fibers, their principles of coupling with high efficiency and processes as well as characteristics are presented. A new scheme to enhancing coupling efficiency and alignment tolerance and reducing insert loss for LD and fiber by cascading GRIN and SMF is reported.
