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

Nonlinear Spectral Broadening in Solid-Core Bragg Fibers
TL;DR: In this article, a detailed theoretical study of nonlinear pulse propagation through solid-core photonic bandgap Bragg fibers is presented, where the influence of the fiber structure and various parameters of the input pulse on the spectrum of the output pulse are studied, with an aim to achieve Bragg fiber designs that have the potential for nonlinear applications such as continuum pulse generation.
