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 fiber optical correlation spectroscopy gas sensor
TL;DR: In this article, the authors present results obtained from the first all-fiber, lensless optical correlation spectroscopy gas sensor for acetylene (C) which relies upon comparison of the absorption spectrum of acetylene held in a reference gas cell to that of a gas sample under test, which is contained in the measurement cell.

TL;DR: Measuring the total output power at the end of the fiber as a function of the angle of incidence of the exciting laser beam provides a powerful diagnostic for characterizing the cladding bandgap.

Birefringence properties of anti-resonant octagonal-core and nodeless hollow-core fibers.
TL;DR: Experimental results of birefringence property measurements for two types of negative curvature anti-resonant hollow-core fibers demonstrate that both fiber types have bireFringence axes that do not correspond to core symmetry axes.

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.

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.
