Photonic restricted Boltzmann machine for content generation tasks
Li Luo, Yisheng Fang, Wanyi Zhang +1
The restricted Boltzmann machine (RBM) is a neural network based on the Ising model, well known for its ability to learn probability distributions and stochastically generate new c…
Antiferromagnetic spatial photonic Ising machine through optoelectronic correlation computing
Junyi Huang, Yisheng Fang, Zhichao Ruan
Recently, spatial photonic Ising machines (SPIM) have been demonstrated to compute the minima of Hamiltonians for large-scale spin systems. Here we propose to implement an antiferr…
Experimental Observation of Phase Transitions in Spatial Photonic Ising Machine
Yisheng Fang, Junyi Huang, Zhichao Ruan
Statistical spin dynamics plays a key role to understand the working principle for novel optical Ising machines. Here we propose the gauge transformations for spatial photonic Isin…
Optical computation of divergence operation for vector field
Yijie Lou, Yisheng Fang, Zhichao Ruan
Topological physics desires stable methods to measure the polarization singularities in optical vector fields. Here a periodic plasmonic metasurface is proposed to perform divergen…
On-grating graphene surface plasmons enabling spatial differentiation in terahertz region
Yisheng Fang, Yijie Lou, Zhichao Ruan
We propose a graphene-on-grating nanostructure to enable second-order spatial differentiation computation in terahertz (THz) region. The differentiation operation is based on the i…
