The 15th China Optoelectronics Industry Expo, which will be held in Beijing from July 23-26, 2024, will display the selected results of the "Three-Year Outstanding Achievements in Silicon-based Optoelectronics". The Center's "Highly Parallel, Ultra-Wideband Silicon-based Optoelectronics System-on-Chip" has been selected.

Silicon-based optoelectronics technology stands at the forefront of the technological revolution and is the core enabling technology for the future information age. The "Three-Year Outstanding Achievements in Silicon-based Photonics" organized by the Optical Engineering Society of China aims to comprehensively review and display the academic achievements of silicon-based photonics technology and the development of theories, technologies and products related to the industrial chain. Through this activity, the weak links in the ecosystem will be revealed, which will provide strong support for the future development direction and stimulate the potential for greater application of silicon-based optoelectronics.

Highly parallel, ultra-wideband silicon-based optoelectronics system-on-chip

Prof. Xingjun Wang's team at Peking University has achieved a series of breakthroughs in broadband high-performance silicon-based single-component device design as well as large-scale silicon-based integrated information system, which has contributed to the broadband and high-speed development of silicon-based photonics technology. In terms of single-component devices, the team has developed high-efficiency heterogeneous integrated silicon-based parallel light source, ultra-high-bandwidth silicon-based slow-light modulator, high-Q photonic molecular resonator cavity and other device design methods, and realized the highest bandwidth of electro-optical conversion of the pure silicon MZ modulation device and high-Q broadband signal processor devices. In terms of integrated information system, we have proposed for the first time a highly parallel integrated optoelectronics system-on-chip architecture based on microcavity optical comb drive, which realizes highly parallel and high data throughput information transmission and processing on multiple integrated systems such as optical interconnect, microwave photonics, and optical computing. Meanwhile, the development of fully integrated optoelectronic fusion information system design methodology and the adoption of heterogeneous/hybrid integration scheme have realized the first silicon-based broadband instantaneous frequency measurement, high degree-of-freedom silicon-based microwave photonics filtering and multi-channel optoelectronic integrated transceiver and receiver, which have pushed forward the advancement of optoelectronic fusion integrated system.
