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

Radiation-induced effects in a new class of optical waveguides: the air-guiding photonic crystal fibers
TL;DR: In this paper, the authors characterized the vulnerability of air-guiding photonic crystal fibers (Air-PCF) by measuring the time dependent changes of their radiation-induced attenuation (RIA) at 1.55 /spl mu/m.

Guiding properties and dispersion control of kagome lattice hollow-core photonic crystal fibers
TL;DR: It is shown that while the loss is mainly influenced by the strut thickness of the kagome lattice the group velocity dispersion is almost independently controlled by the core size and therefore kagomes have a promising potential in ultrashort pulse delivering of high-energy pulses and in several interesting applications in ultrafast nonlinear optics.

Photonic bandgap fiber tapers and in-fiber interferometric sensors
TL;DR: Nonadiabatic tapers in hollow-core air-silica photonic bandgap fibers (PBFs) were fabricated by the use of a fiber fusion splicer because the innermost rings of air holes were found collapsed or significantly deformed, which results in almost doubling the diameter of the hollow core in the tapered region.

Microstructured Optical Fiber Sensors
TL;DR: In this paper, a review of microstructured optical fiber (MOF) sensors is given, including measurement of physical parameters, e.g., pressure, strain, torsion, temperature, and the detection of biomedical parameters.

Optical waveguide monitoring
TL;DR: In this paper, techniques for detecting and localizing defects in optical waveguides (e.g., photonic crystal fibers) are described. But these techniques are limited to the case of optical waveguide Pulses of light are launched into one end of a waveguide.

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.
