Super Disk Selected among 2024 Top Ten Advances in Chinese Optics

On March 29th, Chinese Laser Press released the " 2024 Top Ten Advances in Chinese Optics ". After multiple rounds of selection by the review committee, "A 3D nanoscale Optical Disk Memory with Petabit Capacity" was ranked first among one of the "2024 Top Ten Advances in Chinese Optics" (Applied Research).

On February 22, 2024, the research achievement "A 3D nanoscale optical disk memory with petabit capacity", jointly completed by researchers from USST, Chinese Academy of Sciences, Shanghai Institute of Optics and Fine Mechanics and some other institutions, was published in Nature. The team first proposed and focused on the principle of dual beam-controlled aggregation induced luminescence, which broke through the limitations of optical diffraction in both information writing and reading, and verified the nano photon storage technology with a single disk equivalent capacity of 1.6 Pb. This technology can provide energy-saving, low-cost, and ultra-large capacity data storage solutions, which is of great significance for China to break through key core technologies in the field of information storage. Academician Gu Min, Dean of the Institute of Photonic Chips at USST, is the main corresponding author, while Dr. Wenjing from Zhangjiang Laboratory and USST, and Dr. Ruan Hao from Shanghai Institute of Optics and Fine Mechanics are co-corresponding authors.

Recently, this achievement was also selected as one of the "2024 Top 10 Scientific and Technological Developments in China in 2024" by academicians of the Chinese Academy of Sciences and Chinese Academy of Engineering, as well as the "2024 Top 10 Social Impact Events in Chinese Optics" (Light 10).
