WUHAN, China (February 6, 2023) - Wuhan Optoelectronics Forum No. 182 was successfully held in Auditorium C111 at Wuhan National Laboratory for Optoelectronics (WNLO) in the morning of February 6. Professor Lai Wang from the Institute of Information and Optoelectronics Technology, Department of Electronic Engineering, Tsinghua University delivered an inspiring speech entitled Miniaturization of Optoelectronic Devices: Demands, Challenges and Critical Technologies. Professor Jiang Tang, Associate Director of WNLO, chaired the forum and awarded Professor Lai Wang the forum medal.
Professor Wang introduced the development, composition and discipline positioning of Integrated Optoelectronic Devices and Applications Research at Tsinghua University. He talked about the change of research focus in the Department and the historical mission of researchers, and explained how to cultivate students' interest in optoelectronics research and set up courses. In the field of miniaturization of optoelectronic devices, Professor Wang outlined three aspects of work in his team, including Micro-LED chips for new displays, integrated memory-computing arrays, and new manufacturing technologies for semiconductor devices based on van der Waals/exfoliation transfer. These research deployments, focusing on the core demands for miniaturized optoelectronic devices, cover the whole chain of technologies from wafer growth, chip manufacturing, module packaging, to system evaluation and testing. The atmosphere at the report was lively, and the teachers and students of the research center had a lively exchange with Professor Wang on the content of the report.
Lai Wang is an Associate Professor of the Department of Electronic Engineering and Director of the Information and Optoelectronics Technology at Tsinghua University. He is a recipient of the National Science Fund for Distinguished Young Scholars.
