Fibers and planar waveguides made from dielectric materials which are periodically patterned on the scale of the optical wavelength--photonic crystals--have quite remarkable properties, requiring a complete realignment of the goal- posts in conventional guided-wave photonics. For example, photonic crystal fibers can be designed to be single-mode at every frequency, and full 2D photonic bandgaps can permit light to be guided--single mode--in a core region where the refractive index is lower than the cladding. A whole menagerie of new possibilities are presently emerging, including hollow-core single-mode optical fibers and ultra- compact micro-components formed in planar photonic crystal films.
