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

Modelling of a novel hollow-core photonic crystal fibre
TL;DR: In this paper, a hollow core photonic crystal fiber that guides light over a broad range of frequencies has been developed, and it is shown that guidance is due to a low density of states of the cladding structure near the air line.

A comparative study of Raman enhancement in capillaries
TL;DR: In this article, the authors compared the performance of hollow core photonic crystal fibers (HCPCFs) to conventional Teflon capillary tubes for different lengths of the waveguide and showed that for an optimal waveguide length, two orders of magnitude enhancement can be achieved for aqueous solutions using HCPCFs.

Nanomaterials for textile processing and photonic applications
TL;DR: A review summarises the results of certain individual toxicity trials and the extensive joint programs planned in both Europe and America as mentioned in this paper, which is mainly during the past decade that they have been extensively developed for an amazing range of end uses, some in textile dyeing and finishing but more particularly in a technology now referred to as photonics.

Full 2-D photonic bandgaps in silica/air structures
