TLDR
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.Abstract:
The confinement of light within a hollow core (a large air hole) in a silica-air photonic crystal fiber is demonstrated Only certain wavelength bands are confined and guided down the fiber, each band corresponding to the presence of a full two-dimensional band gap in the photonic crystal cladding Single-mode vacuum waveguides have a multitude of potential applications from ultrahigh-power transmission to the guiding of cold atomsread more

Microstructured optical fibre with tunable birefringence
TL;DR: In this article, an approach for manipulating and tuning birefringence in a microstructured photonic crystal optical fiber is presented, which is accomplished by filling certain airholes with an index tunable polymer which creates a tunable asymmetry in the index profile of the cladding.

Squeezed hexagonal highly birefringent photonic crystal fiber with low effective modal area
TL;DR: In this paper, a modified hexagonal index guiding photonic crystal fiber made of pure silica with high birefringence and a low effective modal area was proposed, and properties, including bireringence, were numerically analyzed using the multipole method.

Low-loss micro-machining of anti-resonant hollow-core fiber with focused ion beam for optofluidic application
TL;DR: In this paper, focused ion beam (FIB) milling on a nodeless anti-resonant hollow core fiber (ARHCF) was used to create a 50 µm deep fluidic channel, followed by the 2.8 µm gap between adjacent 500 nm thin capillary tubes.

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.

Hollow metallic and dielectric waveguides for long distance optical transmission and lasers
TL;DR: In this paper, the field configurations and propagation constants of a hollow circular waveguide made of dielectric material or metal for application as an optical waveguide were determined and the increase of attenuation due to curvature of the axis was also determined.

Photonic Band Gap Guidance in Optical Fibers
TL;DR: A fundamentally different type of optical waveguide structure is demonstrated, in which light is confined to the vicinity of a low-index region by a two-dimensional photonic band gap crystal.

Full 2-D photonic bandgaps in silica/air structures
TL;DR: In this paper, full 2D photonic bandgaps are demonstrated for all polarisations in structures with refractive index contrast as small as that of silica and air, and a new type of optical fiber based on these structures is proposed.
