THz Quantum Well Detector Helps China Successfully Develop New Chips
[China Instrument Network Instrument Development] High-speed imaging technology is one of the important research directions in the application of terahertz (THz) technology. Chinese scientists have succeeded in developing a THz frequency upconversion imaging chip capable of pixel-free imaging recently. The relevant research results have been published in the "Science Report", a subtitle of the British magazine "Nature."
The use of THz technology to develop high-speed imaging technology has important application value in material analysis, high-energy physics process analysis, biomedical imaging, human body security and so on. However, due to the lack of low-temperature matching readout circuits, the design of fast-response photon-type focal plane array detectors is very difficult. As a result, the research progress of THz high-speed and real-time imaging technologies is slow.
To solve this problem, the research team led by Cao Juncheng, a researcher of the Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences, used molecular beam epitaxy to stack THz quantum well detectors (THz QWP) and light emitting diodes (LEDs). THz frequency upconversion imaging chip (THz QWP-LED) that can be image-free.
The successful development of the above-mentioned imaging chip is an important advancement of THz high-speed imaging technology, which is of great significance for the development of high-speed high-energy high-energy physical processes, material analysis, and biomedical imaging technologies.
