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

Photonic bandgap fibers
Liang Dong,Peng Xiang +1 more
TL;DR: In this article, photonic bandgap fibers designed to provide a desired dispersion spectrum are discussed, and designs for achieving wide transmission bands and lower transmission loss are also discussed, including low index cladding features distributed along concentric rings or circles.

TL;DR: This paper measures the first hollow-core fiber employing Perturbed Resonance for Improved Single Modedness (PRISM), where unwanted modes are robustly stripped away, and indicates this measured loss can be improved.

Fundamental-mode cutoff in a photonic crystal fiber with a depressed-index core.
TL;DR: A photonic crystal fiber with a depressed-index core doped with fluorine is reported, which matches that of the core at an antiguiding wavelength, below which the fiber does not guide light at all.

UV Absorption Spectroscopy in Water-Filled Antiresonant Hollow Core Fibers for Pharmaceutical Detection.
Mona Nissen,Brenda Doherty,Jonas Hamperl,Jens Kobelke,Karina Weber,Thomas Henkel,Markus A. Schmidt +6 more
TL;DR: The concept of UV spectroscopy in liquid-filled anti-resonant hollow core fibers, with large core diameters and lengths of approximately 1 m, is introduced, which principally improves the concentration detection limit by two orders of magnitude while using almost the entire sample volume—that is three order of magnitude smaller compared to cuvette based approaches.

Synthesis of Vertically Aligned Hollow Platinum Nanotubes with Single Crystalline Nanoflakes
TL;DR: In this article, a methodology for synthesizing vertical arrays of hollow platinum nanotubes with single-crystalline nanoflakes was presented, where the resulting nickel nanorods were immersed in a Pt-ion-containing aqueous solution, the nickel metal dissolved into Ni2+ ions through spontaneous galvanic replacement with Pt ions.

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

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.
