Center for Terahertz Technology Research
 I.                  Introduction

         Center for Terahertz Technology Research (CTTR) of Chongqing Institution of Green and Intelligent Technology (CIGIT), Chinese academy of Sciences was founded in December, 2012. CTTR aims at building a terahertz detection system including the terahertz sourcesbased on the new theories and methods in terahertz technology field. It devotes to utilizingterahertz technologies inimportant basis and application fields, such as non-destructive testing, optoelectronic communication, semiconductor, biomedicine imaging, and gene diagnosis.

       CTTR will build an interdisciplinary research team composed of scientists from mathematics, physics, informatics, material and life science etcwith strong theoretical and application backgrounds. Now CTTR has set up a research team including the Thousand Talents Plan Adjunct Professor Cui Hongliang and Professor Du Chunlei, a senior expert in optoelectronic field. CTTR has started a theoretical and experimental study of terahertz wave imaging and detecting for biomacromolecules, equipped a terahertz biomedicine detection system, sponsored or participated in four national or region significant projects and obtained research funds over 10 million.    


II.   Research Interest

(i)                Experimental and theoretical studies on Bio-macromolecular Terahertz spectroscopy and imaging

Try tobuild a bio-macromolecular THz spectrum and imaging equipment to realize the real-time and dynamic observation and the interaction studies of biomolecules on the micro-/nano-size.


(ii)             THz non-destructive testing of composite materials

Set up the non-destructive testing experimental methods. Testing materials include fiber, plastics, glass, ceramics etc.


(iii)           Generation of high-power THz source

Design and develop 1w above THz sources for accurate sample testing under the strong absorption and low signal-to-noise ratio conditions and for high-throughput full-field and real time Thz imaging.
