Photonic crystals are described. A numerical method for calculating the band-structures for such crystals is explained and the appearance of forbidden frequency gaps is shown. This is used to explain the principle of a completely new kind of optical fibers with novel qualities. It is found that these fibers may guide light along a low index air-column, in accordance with the fact that they do not guide by total internal reflection.
