Abstract: Demand is increasing for higher data rate in wireless communications in order to keep up with the remarkable speed-up of fiber-optic networks such as Ethernet LANs. One of the most direct and easiest ways to achieve a higher data rate of 10-100 Gbit/s is to increase carrier frequencies to terahertz regions of from 100 GHz to 500 GHz. This paper will review our recent challenges for high-speed wireless communications technologies using terahertz electro-magnetic waves.
Keywords: Wireless communications, Terahertz, Photodiode, Giga-bit.
