A minimalist terahertz direct modulator-based real-time high-speed communication system

One of the promising technologies for the upcoming generation of information technology is terahertz wireless communication. Nevertheless, at this moment, neither the mixing modulation system nor the optical beat system in terahertz communication can satisfy the demands of minimalist high-speed real-time transmission for urban data hotspots and wireless transmission in supercomputing centers or other scenes. This paper presents a simple communication system based on a terahertz direct modulator and detector that realizes the direct transmission of camera images without AD/DA, confirms the applicability of a terahertz direct modulation communication system, and establishes the groundwork for further realizing the simple real-time communication of 100 meters and 100 Gbps.
