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

Partially liquid-filled hollow-core photonic crystal fiber polarizer
TL;DR: A compact fiber polarizer is demonstrated by the filling of selected air holes of a hollow-core photonic crystal fiber with a liquid, which results in an asymmetric waveguide structure, leading to a large polarization dependent loss.

An overview on fabrication methods for polymer optical fibers
TL;DR: An overview of the most important materials and fabrication methods for polymer optical fibers is given in this paper, where a newly developed continuous melt spinning process for graded-index fibers is presented that uses rapid cooling in a water quench for the profile formation.

TL;DR: In this paper, a novel highly nonlinear photonic crystal fibers (HN-PCFs) with flattened chromatic dispersion and low confinement losses is described. But the proposed design has been simulated based on the finite-difference method with anisotropic perfectly matched layers absorbing boundary condition.

All-silica single-mode optical fiber with photonic crystal cladding
TL;DR: The fabrication of a new type of optical waveguide: the photonic crystal fiber that supports a single robust low-loss guided mode over a very broad spectral range of at least 458-1550 nm.

Endlessly single-mode photonic crystal fiber.
TL;DR: An effective-index model confirms that an all-silica optical fiber made by embedding a central core in a two-dimensional photonic crystal with a micrometer-spaced hexagonal array of air holes can be single mode for any wavelength.

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.
