The present invention relates to a new class of optical waveguides, in which waveguiding along one or more core regions is obtained through the application of the Photonic Bandgap (PBG) effect. The invention further relates to optimised two-dimensional lattice structures capable of providing complete PBGs which reflect light incident from air or vacuum. Such structures may be used as cladding structures in optical fibres where light is confined and thereby guided in a hollow core region. In addition, the present invention relates to designs for ultra low-loss PBG waveguiding structures, which are easy to manufacture. Finally, the present invention relates to a new fabrication technique which allows easy manufacturing of preforms for photonic crystal fibres with large void filling fractions, as well as a high flexibility in the design of the cladding and core structures. |
