| Opis: | This paper presents a novel system for generating and receiving quasi-continuous (QC)
TeraHertz (THz) waves. A system design and theoretical foundation for QC-THz signal generation
are presented. The proposed QC-THz system consists of commercially available photo-conductive
antennas used for transmission and reception of THz waves and a custom-designed QC optical
signal generator, which is based on a fast optical frequency sweep of a single telecom distributedfeedback laser diode and unbalanced optical fiber Michelson interferometer used for a high-frequency
modulation. The theoretical model for the proposed system is presented and experimentally evaluated. The experimental results were compared to the state-of-the-art continuous-wave THz system. The comparison between the continuous-wave THz system and the proposed QC-THz system
showed the ability to transmit and receive QC-THz waves up to 300 GHz. The upper-frequency limit
is bounded by the length of the used Michelson interferometer. The presented design of THz signal
generation has a potential for industrial application because it is cost-efficient and can be built using
commercially available components. |
