Research Area:
With the support from Academician Zhuang Songlin, the team of Terahertz Science and Technology was built in 2008. After more than 10 years, the team has formed a well-aged structure where more than 20 members joined in, with Professor Zhu Yiming as the leader, and other outstanding young talents at a ministerial or provincial level and young faculties. National basic science centre—terahertz science and technology frontier, provincially and ministerial collaborative innovation centre of terahertz spectrum and imaging technology, and USST-LWSU (Lomonosov Moscow State University) have been approved. Funded by key research projects of the ministry of education, 973Program, 863 Program and the national natural science foundation, the team has paved away with practical terahertz imaging and spectrum system.
The main research fields of the team include Terahertz quantum electromagnetism theory, terahertz radiation mechanism research, terahertz physical mechanism of new topological materials, interaction mechanism between terahertz wave and micro nanostructure, broadband terahertz radiation source, terahertz plasma functional devices, practical terahertz imaging and spectroscopy and other their applications.
Infrastructure:
The team is an important part of the “Shanghai Key Laboratory of Modern Optical Systems”, the “Center for Optical Instruments and Systems Engineering of the Ministry of Education” and the “Collaborative Innovation Center for Shanghai Terahertz Spectrum and Imaging Technology”. It has 300 of 10000 level and 1000 level super clean room, terahertz network analyzer, terahertz probe station, terahertz quantum cascade laser, scanning electron microscope, lithography machine, inductive coupling plasma etching machine, terahertz near field test system and terahertz spectrum testing system.
Group leader: Gu Min
Honours and Achievements:
In terms of terahertz source, the project team has undertaken 14 national-level projects, including 1 project of National Key Basic Research Program of China (973 Program), 5 special projects for the National Key Foundation for Exploring Scientific Instrument,5 projects of National Natural Science Foundation of China and 3 projects of Shanghai Natural Science Fund, the total amount exceeds 35 million yuan. In recent years, the team has published nearly 100 papers (40 ranking top 5 % in the optical field), including 5 ESI papers. Some research in terahertz surface plasma is rated as the first level in international advanced characteristic research direction by the Shanghai Discipline Assessment Center of Shanghai Jiaotong University. (total number of papers and highly-cited papers globally ranked top 1). The point of team member construction is the development of Keysight-USST Joint Terahertz Laboratory and Terahertz Technology Innovation International Joint Laboratory. In the previous research, we carried out research on terahertz basic theory, related devices and terahertz application systems, covering:
1. Terahertz surface excimer mode splitting theory research;
2. Terahertz components: carried out research based on femtosecond laser pumping broadband terahertz radiation source, as well as various types of core devices such as terahertz absorbers, filters, ultra-thin imaging and logic gates;
3. Terahertz systems based on key core devices: Based on the above sources and functional devices, the project application team independently developed a productized time-domain terahertz spectrum system. The system was applied to the detection of swill-cooked oil and won the Excellent Exhibition Award of the 14th China International Industry Fair.
The team has invested heavily in the direction of instrument development. At present, it has terahertz swill-cooked oil detection equipment (parameter: signal-to-noise ratio 65dB), terahertz near-field scanning device (parameter: spectral width 0.05-1.5THz, spatial resolution 0.2μm, signal-to-noise ratio 40dB,sampling time interval 50ms,spectrum resolution 15GHz). All of them meet the technical parameters of similar products in the world. The related products have been sold overseas, such as Pakistan and domestic universities, producing good economic and social benefits. The team has transferred or licensed three patents, with total funding of 28.68 million yuan.
