摘要: 为了获得色散平坦特性良好的光子晶体光纤，采用有限元法进行了理论分析和实验验证，取得了有效折射率、色散系数随波长的变化数据。当空气孔直径d=1.6μm、孔间距Λ=2μm时，在1.2μm~2.1μm波段内，色散平坦特性较好，且在1550nm波长处的色散系数值为108.20ps/（nm·km），并在此结构基础上，研究了填充材料、不同填充方式对色散特性的影响。结果表明，采用"十"字形的填充方式获得的色散特性更好，当采取普通酒精为填充材料时，波长在1550nm处的色散系数值可以减小到20.39ps/（nm·km），接近G.652标准单模光纤在1550nm处的色散系数值。这一结果对光通信领域的研究是有帮助的。Abstract: In order to obtain photonic crystal fibers with good dispersion characteristics, by the finite element method, the theoretical analysis and experimental verification were carried out, and the effective index of refraction and dispersion coefficient with the change of wavelength were obtained. According to the analysis results, when the hole diameter d=1.6μm and the hole spacing Λ=2μm, the dispersion flatness is better in the 1.2μm~2.1μm band and the dispersion coefficient is 108.20ps/(nm·km) at the wavelength of 1550nm. Based on this structure, effect of different filling modes and filling material on the dispersion characteristics was studied. The results show that better dispersion characteristics are obtained for the "十" shape filling method, and that when ordinary alcohol is used as filling material, the dispersion coefficient at the wavelength of 1550nm can be reduced to 20.39ps/(nm·km), which is close to that of a G.652 single mode fiber at 1550nm. This result is helpful for research in the optical communication field.
