On May 18, 2022, together with PKU Wang Xingjun’s group and UCSB John E. Bowers’s group, we published the article “microcomb driven silicon photo systems” online in Nature journal. This paper reports the new silicon-based optoelectronic on-chip integration system driven by integrated microcavity optical comb for the first time in the world, which shows that the research team spent three years working together to overcome this worldwide problem.

By directly pumping the integrated micro cavity optical frequency comb by semiconductor laser, the team provides the required light source brain for silicon-based optoelectronic integration chip, and completes the efficient parallelization of large-scale integration system in combination with the mature and reliable integration solutions in the industry of silicon-based optoelectronic integration technology. Using this highly integrated system, T-bit rate micro communication and sub GHz microwave photonic signal processing are realized. A new architecture of high-density multi-dimensional multiplexing micro communication and micro processing chip level integration system is proposed, which creates the development of the next generation multi-dimensional silicon optical integration micro system sub discipline. Relevant research results are expected to be directly applied to data center, 5 / 6G communication, automatic driving, optical computing and other fields, providing a new research paradigm and development direction for the next generation on-chip optical electronic information system.
