title: Hole-assisted dual concentric core fiber with ultralarge negative dispersion coefficient of -13,200 ps/nm/km.
abstract: We propose a dual concentric core fiber (DCCF) with six homogeneous air holes, designed to realize a large negative dispersion coefficient. We clarify numerically that the dispersion property of the proposed DCCF can be controlled flexibly by adjusting the air-hole structure, and we realize the largest reported negative dispersion of -13,200 ps/nm/km experimentally.
