Dynamically Reconfigurable Optical Skyrmions Enabled by a Silicon Microring Optical Phased Array for Robust Free-Space Communication
Zili Cai, Tian Zhang, Qi Chen +3
Optical skyrmions offer a robust vectorial information degree of freedom for free-space communication, but practical deployment requires a compact platform capable of active topolo…
Spin Elasticity:A New Paradigm for Spintronics
Zhong-Chen Gao, Tianyi Zhang, Feifei Wang +3
Elasticity shapes our world. For centuries, it has been regarded as a property exclusive to ordinary matter. Here we uncover its hidden existence in the spin degree of freedom. We…
Spin Elasticity
Zhong-Chen Gao, Tianyi Zhang, Feifei Wang +3
Elasticity has long been regarded as a property exclusive to material media. Here we uncover its hidden existence in the spin degree of freedom. We introduce spin elasticity-an int…
Efficient training for large-scale optical neural network using an evolutionary strategy and attention pruning
Zhiwei Yang, Zeyang Fan, Yihang Lai +4
MZI-based block optical neural networks (BONNs), which can achieve large-scale network models, have increasingly drawn attentions. However, the robustness of the current training a…
RoNo: A novel way in generating reconfigurable on-chip nonlinear activation functions
Zili Cai, Tian Zhang, Jian Dai +2
Due to the limitations of Moore's Law and the increasing demand of computing, optical neural network (ONNs) are gradually coming to the stage as an alternative to electrical neural…
