Photonics-enabled terahertz communications towards terabit/s

Almost 15 years have passed, since the first demonstrations of terahertz (THz) wireless communications were made using both impulse and continuous waves. THz communications have recently gained greater interest and expectation to meet an ever-increasing demand for the speed of wireless communications. This paper overviews a latest trend of THz communications research focusing on how photonics technologies have played a key role, and discuss a future strategy towards 1 Tbit/s.
