Broadband submicron flattened dispersion compensating fiber with asymmetrical fluoride doped core
Original language description
The goal of this paper is to investigate selected fluoride optical materials and to present a photonic crystal fiber designed for specific applications in dispersion compensation by using those materials. The idea how to restrict chromatic dispersion isto increase the index contrast by using calcium fluoride or barium fluoride in the first ring of holes, which lower the effective index. The use of fluorides allows achieving broadband dispersion suppression impossible to achieve in standard fibers withsimilar geometry. The presented result comprises a numerical model of a photonic crystal fiber in a submicron lattice, specific for its negative dispersion coefficient achieved for broad spectrum of telecommunication wavelengths, i.e. 1300 ? 1700 nm. Holes doped with fluoride materials enhance negative dispersion coefficient to -438 ps.nm-1.km-1. The major advantage of the designed fibers is their material composition, low attenuation and broadband utilization.
