Inverse design and fabrication tolerances of ultra-flattened dispersion holey fibers

By F. Poletti, V. Finazzi, T.M. Monro, N.G.R. Broderick, V. Tse and D.J. Richardson


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 µm 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
