Science China(Information Sciences) 2020年第6期63卷 105-118页

作者： Bowen BAI Haowen SHU Xingjun WANG Weiwen ZOU State Key Laboratory of Advanced Optical Communications System and Networks School of Electronics Engineering and Computer Science Peking University Frontiers Science Center for Nano-optoelectronics Peking University State Key Laboratory of Advanced Optical Communication Systems and Networks Intelligent Microwave Lightwave Integration Innovation Center(iMLic) Department of Electronic Engineering Shanghai Jiao Tong University

Brain-inspired photonic neural networks for artificial intelligence have attracted renewed interest. For many computational tasks, such as image recognition, speech processing and deep learning, photonic neural networks have the potential to increase the computing speed and energy efficiency on the orders of magnitude compared with digital electronics. Silicon Photonics, which combines the advantages of electronics and photonics, brings hope for the large-scale photonic neural network integration. This paper walks through the basic concept of artificial neural networks and focuses on the key devices which construct the silicon photonic neuromorphic systems. We review some recent important progress in silicon photonic neural networks, which include multilayer artificial neural networks and brain-like neuromorphic systems, for artificial intelligence. A prototype of silicon photonic artificial intelligence processor for ultra-fast neural network computing is also proposed. We hope this paper gives a detailed overview and a deeper understanding of this emerging field.

In the information explosion era, the demand for high-density stable storage technologies is soaring. Multi-dimensional optical storage with femtosecond laser writing offers a potential solution for massive data storage. However, equipment instability and reduced voxel resolution inevitably lead to data errors. Here, we propose and demonstrate a paradigm exemplifying high-fidelity eternal lifetime optical storage enabled by error correction mechanism. We increase information density by reducing voxel size and spacing. Leveraging deep learning methods, we achieve 8-bit voxel encoding and a storage capacity of 2.15 Tb/disc. We implement the Reed-Solomon(RS) algorithm for error-free data recovery and get the trade-off between the storage capacity and the redundancy length. Our storage paradigm takes advantage of error-correcting codes, together with permanent information storage capabilities of extremely stable fused silica, marking a significant advancement for recording massive data to the application level and making it possible to faithfully record the information generated in human civilization. © 2025, CC BY-NC-SA.
