    Findings by the team of HITSZ's Prof. Xiao Shumin made it to the list of China's Top 10 Optical Breakthroughs During 2021

    On May 23, the Chinese Journal of Lasers released China's Top 10 Optical Breakthroughs During 2021. One of them was a polarization-insensitive broadband achromatic metalens based on titanium dioxide for near-IR biological imaging, developed by the team of Prof. Xiao Shumin from HITSZ's School of Materials Science and Engineering. This offers the possibility of replacing traditional lenses with lightweight metalenses. As a result, onboard optical components for medical imaging can be further miniaturized and integrated. The findings were published as a paper entitled High-efficiency broadband achromatic metalens for near-IR biological imaging window in Nature Communications on September 21, 2021. Its first author is the doctoral student Wang Yujie, its co-first authors are Chen Qinfu, Yang Wenhong, and Ji Ziheng, and its correspondent author is Prof. Xiao Shumin.
