On the morning of October 28, 2023, the 4th Graduates Gatherings of our lab. was held at Tsinghua Tongfang Science and Technology Plaza. More than 40 graduates from all over the country and all walks of life got together.

Prof. Yidong Huang, Wei Zhang, Xue Feng, Kaiyu Cui, Hao Sun, Yongzhuo Li and several senior doctoral students attended the gatherings. Prof. Fang Liu attended the gathering online. Prof. Yidong Huang first delivered an opening speech and warmly welcome all the graduates. She hoped that everyone would pay attention and participate, gather strength, and jointly promote the development of China's optoelectronic industry. After that, Dongning Liu, Tian Tian, Jiayi Ouyang, Zhexuan Wang, Hongteng Lin, Ning Wu, Shijie Rao, and Sheng Xu introduced their latest research progress. Next, graduate representatives Yunxiang Li, Yijie Huo, and Tuo Qu shared their career development and life insights after graduation. Di Qu, CEO of H-chip Tech. Group, Yu Wang, CEO of Seetrum Tech. and Xiangdong Li, CEO of Lightfunction Tech.  introduced the rapid development and growth of the transformation enterprise companies of our Lab. in the past year. It fully demonstrates the graduates' spirit of striving for self-improvement and the courage to take on responsibilities in their careers. Finally, Prof. Wei Zhang, Xue Feng, Kaiyu Cui, Hao Sun, and Yongzhuo Li gave speeches and introduced their research achievements and next steps, recalling the unforgettable time in the laboratory. 

Before the end of the event, Professor Yu Wang, director of the Department of Electronics Engineering, also came to the venue. He introduced the recent development of the department, and encouraged graduates to make their own contributions to the development of China's optoelectronics industry.

We hope that the annual "Graduates Gatherings" can become a platform for graduates to exchange information and share, and play a positive role in promoting the development of your career and the laboratory.
