摘要 微型棱镜侧面耦合方法是目前双包层光纤抽运光耦合的新方向之一,提出一种新型的棱镜耦合方法,并从理论上计算了该方案的耦合效率。采用几何光学方法分析了影响耦合效率的最主要因素——抽运光束相对于微型棱镜入射端面倾斜角度对耦合效率的影响情况;通过数值计算,证实这种棱镜耦合技术的耦合效率理论上可达到90%。是一种具有优化结构的棱镜侧面耦合法。 In this paper, the coupling efficiency in the micro-prism sided-couplirig method of double-cladding fiber was calculated and analyzed. The results show that this inclination of the pumping light to the incident facet of the micro-prism is the factor that affects the coupling efficiency mostly, the coupling efficiency can be larger than 90% in theory.
