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

Light transmission in multiple or single subwavelength trefoil channels of microstructured fibers.
Jean-Marie Moison,Alin Marian Apetrei,Juan Ariel Levenson,Gilles Melin,Ph. Pedeboseq,Anne Fleureau,Simon Lempereur,Laurent Gasca +7 more
TL;DR: The trefoil channels present between the holes of microstructured fibers are evaluated as a potential dense array of small waveguides and show that light can be output in individual channels or in several of them, depending on the injection.

Ultrahigh Temperature Sensitivity Using Photonic Bandgap Effect in Liquid-Filled Photonic Crystal Fibers
TL;DR: In this paper, the temperature responses of two liquid-filled polarization maintaining photonic crystal fibers (PM-PCFs) were theoretically and experimentally investigated, and the guidance mechanism was a hybrid of the modified total internal reflection and photonic bandgap (PBG) principles.

Temperature tunable photonic band gap crystals based on liquid-infiltrated inverse opal structure
TL;DR: In this article, temperature tunable photonic crystals were fabricated based on liquid-infiltrated inverse opal films and the photonic band gaps were investigated at different temperatures by reflection spectra.

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.
