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

Supercontinuum generation in a carbon disulfide core microstructured optical fiber
TL;DR: In this article, the authors demonstrate supercontinuum generation in a liquid-core microstructured optical fiber using carbon disulfide as the core material and demonstrate an extraordinary high conversion efficiency from pump to soliton and to dispersive wave, overall defining a platform that enables studying the impact of noninstantaneous responses on ultrafast soliton dynamics and coherence using straightforward pump lasers and diagnostics.

Spatial vector solitons in nonlinear photonic crystal fibers
TL;DR: In this article, spatial vector solitons in a photonic crystal fiber (PCF) made of a material with the focusing Kerr nonlinearity were studied, and it was shown that these two-component localized nonlinear waves consist of two mutually trapped components confined by the PCF linear and the self-induced nonlinear refractive indices.

Visible continuum generation in air–silica microstructure optical fibers with anomalous dispersion at 800 nm
TL;DR: In this article, the authors demonstrate experimentally that air-silica microstructure optical fibers can exhibit anomalous dispersion at visible wavelengths, and exploit this feature to generate an optical continuum 550 THz in width, extending from the violet to the infrared.
