Terahertz (THz) electromagnetic waves, which are located between the radio and light-wave regions (0.1-10 THz), have recently attracted much attention because of their many potential applications such as spectroscopic sensing, nondestructive imaging and ultra-broadband wireless communications. However, most existing THz-wave systems are cumbersome because they consist of bulky discrete components. Developing compact and integrated THz-wave devices is required to open new possible applications. In case use of metallic transmission lines in THz region, the intrinsic loss of metals becomes serious in contrast to microwave region. Here we focus on a two-dimensional photonic crystal where sufficient confinement of THz waves can be achieved in a thin dielectric structure with ultralow loss, as a THz-wave integration platform. In this paper, we report that the propagation and bending losses of the photonic-crystal waveguide are as small as <0.1 dB/cm and 0.3 dB/bend, respectively, in the 0.3-THz band. Also, we demonstrate 1.5-Gbit/s THz-wave communications and high-definition video transmission in the photonic-crystal waveguide of as long as 50 cm with bends of 28 times thanks to the ultralow loss properties. |
