Abstract :
We demonstrate terahertz photonic-crystal waveguides with ultra-low propagation loss (~0.2 dB/cm) and ultra-low bending loss (<;0.2 dB/bend) in planar compact structure, which is promising to develop a terahertz-wave integrated circuit. 1.5-Gbit/s error free terahertz-wave communications are achieved in the photonic-crystal waveguides as long as 47-cm length with 28-times bends, for the first time.
