The 2025 Symposium on Nano-Optoelectronics was successfully held at the Science and Technology Exhibition Center of China Optics Valley on the afternoon of May 15th. As one of the concurrent events of the International Optoelectronic Exposition and Forum, this symposium was initiated and chaired by Prof. Yidong Huang from Tsinghua University, and jointly organized by Department of Electronic Engineering and the International Research Center for Nano-optoelectronics of Tsinghua University. The symposium provided an excellent platform for experts and scholars in the field of optoelectronics to exchange ideas, share research results, and explore future trends. This symposium attracted more than 100 researchers, industry representatives, and students in the field of optoelectronics for on-site participation, and over 1300 people watched this event through the online streaming platform.

Prof. Yidong Huang from Tsinghua University presided over the symposium and delivered the opening speech. This symposium invited Prof. Xia Guo from Beijing University of Posts and Telecommunications, Prof. Xiulai Xu from Peking University, Prof. Fang Liu from Tsinghua University, Prof. Peining Li from Huazhong University Of Science And Technology, and Prof. Ting Xu from Nanjing University to give presentations on topics of "Research on high performance silicon photomultiplier tube", "The interaction between excitons and microcavities", "Free electron radiation based on micro-& nano-structures", "Near field nano-optical imaging based on van der Waals hyperbolic polariton pulses", and "Multidimensional light field control technology and applications of optical meta-surface", respectively. In addition, previous invited speakers Prof. Xuewen Chen from Huazhong University of Science and Technology attended the event in person to support the discussion on promoting the long-term development of nano-optoelectronics.
