Discuss the research progress of terahertz
Terahertz spectrum is an important strategic resource, and the International Telecommunication Union (ITU) is responsible for the allocation and coordination of spectrum resources, which deserves attention. Terahertz chip design is the industrial application of the "neck" technology, Beijing Key Laboratory of Millimeter Wave and Terahertz, Beijing Institute of Technology, from the development of terahertz Schottky diode, independently developed a number of types of terahertz core devices, in particular, the use of time/division/frequency/quasi-optical synthesis of the development of the ultra-broadband terahertz frequency source; based on these results, developed the first 500GHz terahertz frequency source in China. Based on the above achievements, we have developed the first 500GHz terahertz radar in China, and participated in the development task of the payload of the world's first geostationary meteorological satellite Fengyun-4. Terahertz communication and 6G have become the hotspots of current research, and terahertz array beam tracking, sensing and communication integration have become the core technologies, and finally the future application prospects are envisioned.
