[期刊论文] 作者:Shaofu Xu,Weiwen Zou, 来源:中国光学快报(英文版) 年份:2021
We propose an optical tensor core[OTC]architecture for neural network training.The key computational components of the OTC are the arrayed optical dot-product units[DPUs].The homodyne-detection-based DPUs can conduct the essential com-putat......
[期刊论文] 作者:Rui Wang,Shaofu Xu,Jianping Chen,Weiwen Zou, 来源:中国光学快报(英文版) 年份:2020
We demonstrate a photonic architecture to enable the separation of ultra-wideband signals.The architecture consists of a channel-interleaved photonic analog-to-...
[期刊论文] 作者:Junyan Li,Na Qian,Shiyu Hua,Weiwen Zou, 来源:中国光学快报(英文版) 年份:2021
A microwave-chip-based coherent multi-frequency RF driver is developed for a channel-interleaved photonic analog-to-digital converter[PADC]system,which comprises a multi-class optical demultiplexer and supports a sampling speed of 40 GSa/s.......
