Abstract
The technologies emerging from Terahertz (THz) research have attracted many previously unexplored areas, such as the characterization of negative index materials. Recently, the progress with THz waveguides results in potential of not only flexible THz guiding but also for THz sensing. The variety of THz waveguides made of metals [1] and dielectrics as well as THz photonic crystal fibers (PCFs) [2,3] reported low-loss, low-dispersion THz waveguiding characteristics. We present a new design of THz fiber with metal wires inclusion that enables low loss and low dispersion THz guidance in an essentially air-core region. The fibers are constructed from the PCF fabrication technology, eliminating altogether the mounting complexity of the bare metal wires [4].
