Academician Gu Min introduced that taking the deep learning model GPT as an example, the dataset behind it, such as the total number of indexed web pages is as high as 5.8 billion, and the text size of the entire Internet is about 56Pb. The 3D nanophotonic storage developed by the research team can save storage space to the size of a computer, which greatly reduces the economic cost. In addition, in order to maintain the harsh operating environment of the database (e.g., constant temperature and humidity, magnetic and dust resistance), huge energy consumption needs to be generated. The photonic storage technology developed by the research team can reduce energy consumption by several orders of magnitude, and the lifespan can reach 50 to 100 years.
This game-changing achievement stems from the team's breakthrough in the limits of optical diffraction. For example, laser direct writing machine, optical microscopy technology, optical storage technology, etc., are all limited by the optical diffraction limit. Among the 125 most cutting-edge scientific questions published in the world published by Science magazine in 2021, the optical diffraction limit ranks first in the field of physics, and it is also one of the seven technical fields that will be focused on in the coming year in the latest release of Nature in 2024.
