Terahertz Wireless Communication using Resonant Tunneling Diodes and Practical Radio-over-Fiber Technology

Resonant tunneling diodes (RTD) are a promising technology for efficient generation and detection of terahertz-band wireless signals. At the same time radio-over-fiber (RoF) is an established technology for transmitting high bandwidth data over long distance with minimal signal-loss impairment. This paper investigates the suitability of combining these two technologies as an attractive end-to-end solution. We conduct biterror rate and jitter experiments using both laboratory-grade and consumer-grade equipment for transmission of uncompressed high-definition television signals. Data is transmitted over 1 km of fiber and the wireless signal is transmitted between RTD separated by a distance of 7.5 cm. Our results show that RoF and RTDs are practical and complementary technologies.
