摘　　要：理论分析了空气孔尺寸与晶格常数对光子晶体光纤(PCF)单模特性的影响,设计了大模场双包层PCF的波导结构。采用自主知识产权的专利技术,制备出高数值孔径大模场掺Yb双包层PCF,其内包层数值孔径为0.65,纤芯数值孔径为0.06,有效模场面积为1 465.7μm2。The effects of air-hole size and lattice constant on the single-mode characteristics for photonic crystal fibers（PCFs） are analyzed in theories and the waveguide structure with large mode-field double-cladding photonic crystal fiber is designed.Then the high numerical aperture and large mode-field,ytterbium-doped double-cladding photonic crystal fiber is successfully fabricated with the patent technologies of independent intellectual property rights.The numerical aperture（NA） of its inner cladding is as high as 0.65.Furthermore,the fiber has a lower core-NA of 0.06 and 1 465.7 μm2 effective mode-field area.
