摘要: 提出了一种新型的混合双包层结构的光子晶体光纤。利用多极法对光纤基模的模场分布、双折射、限制损耗及色散特性等进行了数值模拟,通过调节包层空气孔的孔径大小可以有效地控制光纤的双折射和限制损耗特性。结果发现:新设计的光纤具有高双折射低限制损耗特性,光纤结构参数为=1.0 m,d1=d2=d3=0.8 m时,该光纤在C波段(1.53~1.565 m)及L波段(1.57~1.62 m)呈现负色散及负色散斜率。在波长为1.55 m处,双折射高达10-2,限制损耗小于10-5 dB/m。Abstract: In this paper, a kind of hybrid cladding photonic crystal fiber was proposed. The model field distribution, birefringence, confinement loss and chromatic dispersion of fiber fundamental mode were simulated by multipole method. It was found that the newly designed fiber shows relatively higher birefringence and lower confinement loss. Then the birefringence and confinement loss of the hybrid cladding photonic crystal fiber were dominated by cladding air holes in the fiber. Simulation results show that the dispersion and dispersion slope are both negative over C band and L band. The birefringence is higher than 10-2, and the confinement loss is lower than 10-5 dB/m under the condition of =1.0 m,d1=d2=d3=0.8 m at the wavelength of 1.55 m.
