An all-dielectric coaxial waveguide that can overcome problems of polarization rotation and pulse
broadening in the transmission of optical light is presented here. It consists of a coaxial waveguiding
region with a low index of refraction, bounded by two cylindrical, dielectric, multilayer, omnidirectional
reflecting mirrors. The waveguide can be designed to support a single mode whose properties are very
similar to the unique transverse electromagnetic mode of a traditional metallic coaxial cable. The new
mode has radial symmetry and a point of zero dispersion. Moreover, because the light is not confined by
total internal reflection, the waveguide can guide light around very sharp corners.
