On the evening of April 20, China Laser Magazine released "2022 Top 10 Progresses in Chinese Optics". The center's research achievement "microcavity optical comb-driven novel silicon-based optoelectronics on-chip integration system" was selected as "2022 China's top ten advances in optics" (basic research category).

The results of "Parallel Chaotic Lidar System Breaking through Time-Frequency Blocking" of the Center was selected as one of the "2023 China's Top 10 Social Influence Events in Optics" (Light10), which was announced recently.

Light10 is an annual list launched by Light: Science & Applications (https://www.nature.com/lsa/), the leading journal of China's Action Plan for Excellence in Science and Technology Journals (APEJ), in collaboration with Sciencenet, the flagship science communication brand of China Science News (https://www. sciencenet.cn/). sciencenet.cn/), the flagship science communication brand of China Science News, to launch the annual list. "Light10" has been held for five consecutive times since 2019, aiming to find the high "light" moments of Chinese optics in that year. 2023 Annual Award has attracted more than 100,000 people to participate in just a few days, and the number of readers of the articles exceeded 100,000+, attracting widespread attention from the public. It has attracted widespread attention from the public.

Parallel chaotic lidar system breaking through time-frequency blocking

Based on two years of research, the Center and Changlin's group have developed a new multi-channel chaotic light source on silicon substrate, and proposed a parallel LIDAR architecture based on chaotic light combs, which helps to overcome the great challenge of the risk of mutual crosstalk faced by the existing two regimes of LIDAR systems (Time of Flight ToF and Frequency-Modulated Continuous Wave FMCW) in the time and frequency domains, respectively. The two worldwide challenges of LIDAR anti-interference and high-precision parallel detection have been overcome, ensuring high performance and safety while greatly reducing the size, complexity, power consumption and cost of future LIDAR systems. The results are published in Nature Photonics.
