Defect and lattice structure for air-silica index-guiding holey fibers

Abstract

We propose new design parameters for index-guiding holey fiber that can provide flexibility in defect and lattice design and adiabatic mode transformation capability. The new defect consists of a central air hole and a germanosilicate ring surrounding it, which results in a large-area annulus mode profile, low splice losses to standard fiber, 0.7 dB at 1.55 mu m, and chromatic dispersion with a low slope, 0.002 ps/km nm(2).
