Experimental Demonstration of Ultra-broadband Secure Communications at True Terahertz Frequencies
The need for higher data-rates and more ubiquitous connectivity for an ever-increasing number of wirelessly connected devices motivates the exploration of uncharted spectral bands. In this context, Terahertz (THz) communication is envisioned as a key wireless technology of the next decade. For many years, the lack of compact and efficient means to generate, modulate, detect and demodulate THz signals limited the applications of the THz band. However, major advancements related to electronic, photonic and plasmonic THz device technologies is finally closing the THz gap. Moreover, multiple recent theoretical and experimental studies have demonstrated that, despite the frequency-selective absorption losses introduced by water vapor, the THz band supports very large transmission bandwidths, in the form of multiple windows, tens to hundreds of GHz wide, each. This very large bandwidth can be exploited to enable ultra-fast data-rates in the order of Terabit-per-seconds. Alternatively, such vast consecutive spectral resources can be leveraged to enable ultra-broadband spread spectrum techniques for secure communications. In this talk, secure waveform design strategies for THz communications will be discussed, analytically modeled, and experimentally validated by utilizing a state-of-the-art testbed for ultra-broadband communications at true THz frequencies.
