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

Proposal for highly birefringent broadband dispersion compensating octagonal photonic crystal fiber
TL;DR: In this article, a highly birefringent photonic crystal fiber based on a modified octagonal structure for broadband dispersion compensation covering the S, C, and L-communication bands is proposed.

Review of diverse optical fibers used in biomedical research and clinical practice
TL;DR: This review paper provides the necessary background to understand how optical fibers function, to describe the various categories of available fibers, and to illustrate how specific fibers are used for selected biomedical photonics applications.

Generation of achromatic Bessel beams using a compensated spatial light modulator
Jonathan Leach,Graham M. Gibson,Miles J. Padgett,Elric Esposito,Gail McConnell,Amanda J. Wright,John M. Girkin +6 more
TL;DR: This work reports the creation of white-light, achromatic Bessel beams using a spatial light modulator and a prism to compensate for the dispersion, which has a radial wavevector and hence an intensity cross-section which is independent of wavelength.

A fourier tool for the analysis of coherent light scattering by bio-optical nanostructures.
TL;DR: The applications of the Fourier tool have falsified the century old hypothesis that the non-iridescent structural colors of avian feather barbs and skin are produced by incoherent Rayleigh or Tyndall scattering and provided a single method for the analysis of coherent scattering by a diversity of nanostructural classes.

Photonic crystal fibers and fiber lasers (Invited)
TL;DR: In this paper, the authors review the ways in which photonic crystal fibers are affecting and may further affect the development and deployment of fiber laser technology, and present a review of some of the most significant developments in this area.

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.

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.
