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

Radiation hard optical fibers
TL;DR: In this paper, the authors examined currently existing fibers of nearly all types that show sufficient radiation hardness in lengths necessary for their respective applications and considered hydrogen loading or treatment and thermal or photo bleaching which can harden certain fibers or fiber links.

Ultra-High-Sensitivity Temperature Sensor Using a Fiber Loop Mirror Based on a Water-Filled Asymmetric Two-Hole Fiber
Rodolfo Martinez-Manuel,Daniel A. May-Arrioja,Jesus Acevedo-Mijangos,R. Domínguez-Cruz,Daniel Lopez-Cortes,Miguel Torres-Cisneros +5 more
TL;DR: In this paper, the authors presented an ultra-high sensitivity fiber loop mirror temperature sensor based on an asymmetric two-hole fiber (ATHF) filled with distilled water, which allows for larger interaction between the optical mode and the region with large induced birefringence.

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.
