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

Impact of core cladding boundary shape on the waveguide properties of hollow core microstructured fibers
TL;DR: In this article, the authors consider an interaction between the air core modes of hollow core waveguide microstructures and core cladding boundary walls in various shapes, and analyze the mechanisms of light localization in the core claddings boundary walls of negative curvature hollow core microstructured fibers.

Limiting efficiencies of nonlinear-optical processes in microstructure fibers
TL;DR: In this paper, the authors showed that the maximum waveguide enhancement of coherent anti-Stokes Raman scattering in a hollow microstructure fiber relative to the regime of tight focusing is shown to scale as λ 2/αa4 with radiation wavelength λ, the inner fiber radius a, and the magnitude of radiation losses α.

All-silica single-mode optical fiber with photonic crystal cladding

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.
