Abstract
The confinement of light within a hollow core;(a Large air hole) in a silic a-air photonic crystal fiber is demonstrated. Only certain wavelength bands are confined and guided down the fiber, each band corresponding to the pre sence of a full two-dimensional band gap in the photonic crystal cladding. Single-mode vacuum waveguides have a multitude of potential applications fr om ultrahigh-power transmission to the guiding of cold atoms.
