Single-Mode Photonic Band Gap Guidance of Light in Air

R. F. Cregan, 1 B. J. Mangan, 1 J. C. Knight, 1 T. A. Birks, 1 P. St. J. Russell, 1* P. J. Roberts, 2 D. C. Allan 3

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 atoms.
