On May 30, 2023, the Zhongguancun Forum's special conference on major scientific and technological achievements was held in the Pro-exhibition Area of Zhongguancun Exhibition Center, at which 20 major achievements such as 30-micron-thickness flexible foldable glass, the general-purpose visual large model SegGPT, and a new generation of artificial suns were formally released. The Center's scientific research achievement "Silicon Optoelectronics Integrated Chip and Multi-functional System" was released in the section of "Facing the World Frontiers of Science and Technology" of this conference. At the conference, Prof. Wang Xingjun, as the publisher of the achievement, briefly introduced the achievement to the leaders and the audience.

After three years of research and collaboration with Prof. John E. Bowers' team from University of California, Santa Barbara, a new type of silicon-based optoelectronics on-chip integrated system driven by integrated microcavity optical combs has been reported for the first time in the world, which provides a parallel light source through semiconductor lasers pumping the integrated microcavity optical combs, and combines with the architecture of a silicon-based optoelectronics chip-scale high-density multidimensional multiplexing system to realize the Parallelization of large-scale integrated systems. Using this integrated system, T-bit communication and sub-GHz microwave signal processing have been realized, providing a new research paradigm and development direction for next-generation on-chip information systems. The results were published in Nature under the title "Microcomb-driven silicon photonic systems".

The co-first authors of the results are Hao-Wen Shu, a postdoctoral fellow of the Center's Boxin Program (currently employed at the School of Electronics of Peking University as an assistant professor and researcher), Dr. Chang Lin of the University of California, Santa Barbara (currently employed at the School of Electronics of Peking University as an assistant professor and researcher, an independent PI and forming a group), and Yuan-Sheng Tao and Bitao Shen, doctoral students of the Center. Prof. Xingjun Wang and John E. Bowers are the co-corresponding authors of the paper. Academician Shaohua Yu of Pengcheng Laboratory participated in this work and provided important guidance. Key collaborators also include Dr. Wei-Qiang Xie (now Associate Professor at Shanghai Jiaotong University) and Ph.D. student Andrew Netherton at the University of California, Santa Barbara, Center Ph.D. students Ming Jin, Zihan Tao, and Xuguang Zhang, and post-doctoral fellows Ruixuan Chen, Bowen Bai, and Jun Qin (now Associate Professor at the Beijing University of Information Science and Technology). This work is completed by the State Key Laboratory of Regional Optical Fiber Communication Networks and New Optical Communication Systems, School of Electronics, Peking University, as the first unit, and is also an important result of the cooperation with Pengcheng Laboratory, which is one of the core contents of the major research tasks of the Circuits and Systems Department of Pengcheng Laboratory.
