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).

Bragg guiding of domainlike nonlinear modes and kink arrays in lower-index core structures.

TL;DR: In this article, a class of stable nonlinear modes trapped in a lower-index film core sandwiched between two optical lattices, or in the cylindrical core of a radial lattice, imprinted in defocusing media, was introduced.

Vector–vortex solitons in nonlinear photonic crystal fibers

TL;DR: In this paper, a system of two incoherently coupled components in a nonlinear Kerr-type photonic crystal fiber presenting angular momentum in one or both components is studied, and the stability of the different nonlinear modes by means of numerical simulations is analyzed.

Method of making a hole assisted fiber device and fiber preform

TL;DR: In this paper, a tube is overcollapsed around the perimeter of the cladding region to form one or more channels, where the channels bounded on one side by the over-collapsed tube are drawn from the preform.

Studies of the modal properties of circularly photonic crystal fiber (C-PCF) for high power applications

TL;DR: In this article, the guiding properties of a new type of photonic crystal fibers where air-holes are arranged in a circular pattern (C-PCF) with a silica matrix have been investigated.

Spectral interference of frequency-shifted solitons in a photonic-crystal fiber.

TL;DR: Frequency-shifted solitons in a highly nonlinear photonic-crystal fiber are shown to give rise to high-visibility interference fringes in PCF output spectra, indicating flat spectral phase profiles of individual solitONS in the PCFoutput.

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.

Single-Mode Photonic Band Gap Guidance of Light in Air.

TL;DR: The confinement of light within a hollow core (a large air hole) in a silica-air photonic crystal fiber is demonstrated and certain wavelength bands are confined and guided down the fiber.
