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

Structural Optimization of Air-Guiding Photonic Bandgap Fibers for Realizing Ultimate Low Loss Waveguides
TL;DR: In this article, the authors investigate the ultimate low loss property for several realistic core shapes in triangular-type air-guiding photonic bandgap fibers (PBGFs) through a full-vector modal solver based on the finite element method.

Modelling of TiO 2 based slot waveguides with high optical confinement in sharp bends
TL;DR: In this paper, the authors proposed a technique to conserve the confinement of light even in sharp bends of slot waveguides, where the slot was displaced to the positive and negative axis of the bend and observed the variation in the field power.

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

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.
