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

High-birefringence hollow-core fibers and techniques for making same
TL;DR: A hollow core fiber has a cladding comprising a matrix of cells, wherein each cell comprises a hole and a wall surrounding the hole, and the hollow core region comprises a core gap in the matrix, wherein the core gap spans a plurality of cells and has a boundary defined by the interface of the core gaps as mentioned in this paper.

Fabrication and Characteristic of Polarization-Maintaining Photonic Crystal Fiber with Two Big Air Holes Structure
TL;DR: In this article, a photonic crystal fiber with two big air holes was fabricated by the capillary-stacking and drawing method, and the microstructure of the small air holes is found to be well kept through a scanning electron microscope, even with a diameter close to 0.6 μm.

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.
