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

Selectively coated photonic crystal fiber for highly sensitive fluorescence detection
TL;DR: In this article, hollow core photonic crystal fibers (HCPCFs) are used for highly sensitive fluorescence detection by selectively coating the central hole of a HCPCF with fluorophores.

Thermal Drawing of High-Density Macroscopic Arrays of Well-Ordered Sub-5-nm-Diameter Nanowires
TL;DR: The lower limit of nanowire diameters stably produced by the process of thermal fiber drawing and fiber tapering is investigated and continuous reduction of the diameter of an amorphous semiconducting chalcogenide glass is demonstrated.

From molecular precursors in solution to microstructured optical fiber: a Sol-gel polymeric route
TL;DR: In this article, a solid-core photonic crystal fibers with the core derived from non-doped or Erbium-Doped sol-gel silica rods are fabricated.

Simultaneous measurement of refractive index and temperature based on SPR in D-shaped MOF
TL;DR: Results show that the y-polarized peak supported by channel I only shifts with RI variation and is unaffected by the temperature floating, which is very helpful for the design and implementation of a highly sensitive, real-time, and distributed SPR sensor for multi-parameter measurement applications.

Loss-reduced highly birefringent selectively liquid-filled photonic crystal fibers
TL;DR: In this article, the birefringence and loss properties of selectively liquid-filled photonic crystal fibers with the liquid asymmetrically infiltrated into one-line air holes along x -axis were theoretically investigated.

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.
