Novel hole-assisted lightguide fiber exhibiting large anomalous dispersion and low loss below 1 dB/km

We propose a novel holed fiber based on lightguiding by glass index difference and dispersion enhancement by holes. Due to the reduced power fraction in the holes, a record-breaking low loss of 0.82 dB/km at 1550 nm is achieved with extraordinarily large anomalous dispersion of +34 ps/nm/km.
