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

Dispersion and birefringence of irregularly microstructured fiber with an elliptic core
Hyoung-Gyu Choi,Chul-Sik Kee,Kyung-Han Hong,Jae-Hee Sung,Soan Kim,Do-Kyeong Ko,Jongmin Lee,Jae-Eun Kim,Hae Yong Park +8 more
TL;DR: It is demonstrated that this irregularly microstructured fiber with high birefringence and short zero dispersion wavelength is useful for the one-octave-spanning supercontinuum generation suitable for an f-2f interferometric system.

Coexistence of Photonic Bandgap Guidance and Total Internal Reflection in Photonic Crystal Fiber Based on a High-Index Array With Internal Air Holes
TL;DR: In this article, the authors show that both photonic bandgap guidance and modified total internal reflection can simultaneously occur in a chalcogenide-tellurite photonic crystal fiber (PCF) whose cladding is composed of a high-index array with internal regions being air.

Chalcogenide glass microstructured optical fiber as a potential candidate for slow-light generation via stimulated Brillouin scattering
TL;DR: In this article, an alternative optical model for the solid-core chalcogenide glass hexagonal lattice microstructured optical fiber (H-MOF) is explored for prompting the generation of slow-light facilitated through stimulated Brillouin scattering (SBS).

Microstructured fiber and supercontinuum light source
TL;DR: In this article, a microstructured optical fiber with a core region and a cladding region surrounding the core region is shown to have a diameter of at least about 2 μιη, where the inner cladding features have a first characteristic diameter and the outer cladding regions have a second characteristic diameter.

Gamma-radiation effects in pure-silica-core photonic crystal fiber*
TL;DR: In this paper, the steady state gamma-ray radiation response of pure-silica-core photonic crystal fibers (PSC-PCFs) under an accumulated dose of 500 Gy and a dose rate of 2.38 Gy/min was 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.
