All-silica single-mode optical fiber with photonic crystal cladding
Optics Letters, 21, (19), . (doi:10.1364/OL.21.001547).
We report the fabrication of a new type of optical waveguide: the photonic crystal fiber. It consists of a pure silica core surrounded by a silica-air photonic crystal material with a hexagonal symmetry. The fiber supports a single robust low-loss guided mode over a very broad spectral range of at least 458-1550 nm. Also see errata - http://eprints.soton.ac.uk/78010/
