TLDR
In this paper, the optical properties of a photonic crystal fiber including a plurality of longitudinal holes are altered by virtue of the change in cross-sectional area of holes in that region.Abstract:
A photonic crystal fibre including a plurality of longitudinal holes (220), in which at least some of the holes have a different cross-sectional area in a first region (200) of the fibre, that region having been heat-treated after fabrication of the fibre, from their cross-sectional area in a second region of the fibre (190), wherein the optical properties of the fibre in the heat-treated region (200) are altered by virture of the change in cross-sectional area of holes (230) in that region (200).read more

TL;DR: In this paper, a novel dispersion compensating photonic crystal fiber (DC-PCF) for wide-band high-speed transmission systems is proposed, which can obtain a larger negative dispersion coefficient, better dispersion slope compensation, and confinement losses less than 10 −4 ǫdB/m in the entire S+C+L telecommunication band.

Modeling of realistic cladding structures for air-core photonic bandgap fibers.
TL;DR: For the fundamental bandgap, it is found that the bandgap edges shift toward shorter wavelengths when the air-filling fraction f is increased, and the band gap also broadens and the relative bandwidth increases exponentially with f2.
