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…

Generalized spatial differentiation from spin Hall effect of light
Tengfeng Zhu, Yijie Lou, Yihan Zhou +9
Optics naturally provides us with some powerful mathematical operations. Here we experimentally demonstrate that during reflection or refraction at a single optical planar interfac…

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…
