1.  Prof. Ai-Zhen Li, Shanghai Institute of Microsystem and Information Technology, CHINA
Late-Breaking Results: Activities on Mid-Infrared Optoelectronics at SIMIT
Speaker Biography: Li Ai-zhen: graduated from Fudan University in 1958, then joined the Shanghai Institute of Metallurgy, CAS (named SIMIT since 2001). She was appointed as a full professor in 1988, and an authorized Advisor for Ph.D. graduate students. She has been engaged in research on III-V semiconductor materials and devices for both optoelectronic and electronic devices applications. Li was a visiting scholar and visiting professor of Carnegie Mellon University, USA, and Max-Planck Society, Germany. She has served on numerous committees for the International Conference. She was a recipient of the Third World Academy of Sciences 2004 Prizes in Engineering Sciences. She was elected as a foreign associate member of the National Academy of Sciences, the United States of America in 2007.

Summary: Many gases exhibit their basic absorption spectra in the wavelength range between 3-10 μm, quantum cascade lasers (QCLs) operating in this range are an ideal light source for TDlAS absorption spectroscopy technology. In order to accelerate QCL applications to meet the requirements of spectroscopy application, efforts have been made to improve the stabilized performance of QCL materials and devices. The reliablity and reproducibility of mid-infrared QCLs, and the quality of non-cryogenic infrared detectors have been greatly improved, making these devices ready for real-world application. In this talk we will review the activities in SIMIT on InP-based 4-10 μm QCLs, infrared InGaAs detectors, and the primary study on III-V Bismide materials for mid-infrared optoelectronic non- cryogenic lasers.
