Single-material submicron microstructured fibres for broadband applications in exact slope compensation or zero-dispersion propagation

The goal of this paper is to present novel broadband optical fibres suitable for exact dispersion slope compensation of standard fibres used in telecommunications. The results were obtained in a submicron lattice by optimizing the single-material PCF´s geometry, avoiding the use of doping technique. Linear dispersion upon wavelength is achieved concurrently to optimal dispersion slope, which exactly matches the characteristics of ITU-T fibres. Last but not least, a fibre for broadband zero-dispersion transmission is presented. The major advantage of the designed fibres is their material composition, low attenuation and broadband utilization.
