Observation of Moiré Plasmonic Skyrmion Clusters
Lan Zhang, Lipeng Wan, Weimin Deng +5
Skyrmions are topological defects belonging to nontrivial homotopy classes in particle theory. Their remarkably stable topology has recently been observed in electromagnetic waves.…

Spin-orbit interactions of the twisted random light
Benli Li, Yahong Chen, Weimin Deng +3
The twist phase of random light represents a nontrivial two-point phase, endowing the field with orbital angular momentum. Although the mutual transition of the spin and orbit angu…

Edge detection imaging by quasi-bound states in the continuum
Tingting Liu, Jumin Qiu, Lei Xu +6
Optical metasurfaces have revolutionized analog computing and image processing at sub-wavelength scales with faster speed and lower power consumption. They typically involve spatia…
