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

High strength fusion splicing of hollow core photonic crystal fiber and single-mode fiber by large offset reheating
TL;DR: In this paper, the authors proposed a method for high strength fusion splicing between HC-PCF and single-mode fiber with a low splice loss, which greatly improves the reliability of splices between the two types of fiber.

Optical fiber connector cord and optical coupling set including the optical fiber connector cord
Abstract: A optical fiber connector cord capable of being detachably attached to a receptacle fixed to an optical apparatus includes an optical fiber having at least one hole which extends along an optical axis, a plug having a fiber hole through which the optical fiber extends and which is capable of being fitted into the receptacle, a first sealing member which is provided on an outer peripheral surface of the plug and which seals a gap between the plug and the receptacle along the outer periphery of the plug, and a second sealing member which seals a gap between an inner surface of the plug's fiber hole and the optical fiber along the outer periphery of the optical fiber, so that holes in the optical fiber are effectively prevented from communicating with the atmosphere. In addition, an optical coupling set includes the optical fiber connector cord and the receptacle.

Structural and nonlinear optical properties of Crystal-Violet octupolar dyes dispersed in bulk SiO2-sonogel optical-glasses
TL;DR: In this paper, an organic-inorganic bulk hybrid composites with crystal-violet octupolar chromophores was evaluated using absorption and photoluminescent spectroscopies; the linear refractive indices of several highly and slightly CV-doped samples were also estimated according to the Brewster angle technique.

Jin U. Kang,Do-Hyun Kim +1 more
TL;DR: In this article, a temperature dependent birefringence coefficient, dB/dt for a commercially available polarization maintaining photonic crystal fiber was found to be approximately -2.0 times 10-9 /K and can be made smaller.

Supercontinuum generation in low dispersion and highly nonlinear hexagonal photonic crystal fibers
TL;DR: In this article, a solid hexagonal photonic crystal fiber (PCF) with air holes of different diameters in the cladding region using the finite element method was designed to achieve a low group velocity dispersion of −5.483 p2/km and a high nonlinearity of 111.4 p 2/km at 450 nm with d1/Λ being 0.345.

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.
