我们使用遗传算法来优化一系列具有少量空气孔但具有良好限制损耗的开孔光纤(HF)的色散。我们证明了在1.5到1.6微米的波长范围内，对于具有不同横向结构的高频光纤，可以实现0+/-0.1ps/nm/km的色散，并讨论了在色散斜率、非线性和限制损耗方面的一些权衡。然后，我们分析了总色散对特定结构参数最佳值的微小变化的敏感性，并估计了可靠地制造这种光纤所需的制造精度。
We employ a Genetic Algorithm for the dispersion optimization of a range of holey fibers (HF) with a small number of air holes but good confinement loss. We demonstrate that a dispersion of 0 +/- 0.1 ps/nm/km in the wavelength range between 1.5 and 1.6 microm is achievable for HFs with a range of different transversal structures, and discuss some of the trade-offs in terms of dispersion slope, nonlinearity and confinement loss. We then analyze the sensitivity of the total dispersion to small variations from the optimal value of specific structural parameters, and estimate the fabrication accuracy required for the reliable fabrication of such fibers.
