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

A Microfiber Bragg Grating Based on a Microstructured Rod: A Proposal
TL;DR: In this article, a system suitable for the manufacture of microfiber gratings by wrapping a micro-fiber on a microstructured rod, which has large refractive index differences (deep teeth) and a large coupling coefficient, was proposed.

TL;DR: In this article, the effect of modification of silica with high concentrations of germanium up to 36 mol% as well as with highly polarizable dopants (e.g., barium and lanthanum) on optical behavior of microstructured fibers was investigated.

Hole assisted fiber device and fiber preform
TL;DR: A hole-assisted fiber comprises a core region and a cladding region, where the cladding regions includes multiple substantially elliptical holes spaced apart from each other to surround the core region as discussed by the authors.

Highly birefringent photonic crystal fiber based on a double-hole unit.
Daru Chen,Genzhu Wu +1 more
TL;DR: The proposed PCF can achieve birefringence similar to that of an elliptical-hole PCF with high bireFringence even up to the order of 0.01 and still avoid the inherent challenge to fabricate an ellipsoidal PCF.

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.
