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

Telecommunications: a boost for fibre optics.
TL;DR: A possible solution to the need to expand fibre-optic capacities presents itself in the form of a new way of amplifying the information-carrying light transmissions, but turning principle into practice will require more work.

TL;DR: Efficient waveguiding inside low refractive index media is of key importance for a great variety of applications that demand strong light-matter interaction on small geometric footprints and the side-wise access to the core regions and the chip integration makes the light cage concept attractive for agreat number of fields such as bioanalytics or quantum technology.
