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

TL;DR: In this article, the authors present a hybrid material that can be readily produced in water via a one-pot synthesis directly from commercially available, low-cost precursors, yielding systems of an extinction coefficient < 0.01, and a refractive index which can be controlled to adopt values between 1.5 to at least 2.1.

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.

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.
