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

On Guided Waves Created by Line Defects
Dong Miao,Fuming Ma +1 more
TL;DR: In this article, a photonic crystal fiber with a line defect along the axial direction is considered, and a simple condition on the parameters of the medium and of the line defect is given to ensure the rise of eigenvalues in a specified subinterval of the given gap of the photonic fiber.
