7Neuromorphic silicon photonics with 50 GHz tiled matrix multiplication for deep-learning applications显示文摘The explosive volume growth of deep-learning(DL)applications has triggered an era in computing,with neuromorphic photonic platforms promising to merge ultra-high speed and energy efficiency credentials with the brain-inspired computing primitives.The transfer of deep neural networks(DNNs)onto silicon photonic(SiPho)architectures requires,however,an analog computing engine that can perform tiled matrix multiplication(TMM)at line rate to support DL applications with a large number of trainable parameters,similar to the approach followed by state-of-the-art electronic graphics processing units.Herein,we demonstrate an analog SiPho computing engine that relies on a coherent architecture and can perform optical TMM at the record-high speed of 50 GHz.Its potential to support DL applications,where the number of trainable parameters exceeds the available hardware dimensions,is highlighted through a photonic DNN that can reliably detect distributed denial-of-service attacks within a data center with a Cohen’s kappa score-based accuracy of 0.636.George Giamougiannis Apostolos Tsakyridis Miltiadis Moralis-Pegios George Mourgias-Alexandris Angelina RTotovic George Dabos Manos Kirtas Nikolaos Passalis Anastasios Tefas Dimitrios Kalavrouziotis Dimitris Syrivelis Paraskevas Bakopoulos Elad Mentovich David Lazovsky Nikos Pleros 2023Advanced Photonics2023,5,1:0
