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

Numerical simulation of sandwich structure photonic crystal fiber with diameter-increasing air holes
TL;DR: In this paper, a kind of sandwich structure photonic crystal fiber with diameter-increasing air holes is proposed, which is composed of the rectangular lattice in the center and triangular lattice on both sides, which are used to gain high birefringence.

Design of silicon hollow waveguide in-line polarizer using a photonic crystal concept
TL;DR: In this paper, an in-line polarizer based on a hollow waveguide and a one-dimensional photonic crystal concept is proposed and analyzed, where the hollow guide is designed to be symmetric, to achieve maximum coupling with the fiber, while the polarization dependence is achieved through the use of alternating layers of silicon and air.

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.
