Dispersion-flattened photonic crystal fibers at 1550 nm

Abstract

We demonstrate photonic crystal fibers with broadband ultra-flattened dispersion in both the normal and anomalous regimes. A 100 m long fiber with a dispersion of /spl sim/0.5/spl plusmn/0.07 ps/nm.km from 1.42 /spl mu/m to 1.62 /spl mu/m is presented.
