摘要：
Based on optical adherence technique, a novel single-to-double clad fiber coupler for high power double clad fiber laser and amplifier is demonstrated. The coupler is made by polishing a single clad fiber at a small bevel angle and adhered to the doped double clad fiber. In this paper, we design and simulate this fiber coupler and find the coupling efficiency is sensitive to the fiber's parameter. For given fiber's parameter, the coupling efficiency of 80% can be achieved.
