摘要: 将多模光纤末端研磨成圆锥面,与大功率LD进行直接耦合.分析了影响耦合效率的主要因素,提出了在工具显微镜上实现直接耦合的新方法,耦合效率高于50.8%.Abstract: High power LD is directly coupled to the multi-mode optical fiber whose end is uptapered by polishing.Some main factors affecting the coupling efficiency are analysed.Proposed is a novel method of carrying out the direct coupling,with the help of the tool-maker's microscope, a coupling efficiency of higher than 50.8 percent is obtained.
