Valley-locked Optical Spin Merons in Valley Photonic Crystal Waveguides
Lvjin He, Shanshan Chen, Ziyang Chen +4
Optical skyrmionic textures, including Néel-type skyrmions and merons, have attracted significant attention across diverse physical systems for their promising applications in ultr…
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…
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.…
Extremely intrinsic chirality in two-dimensional planar waveguide grating induced by quasi-bound states in the continuum
Dandan Zhang, Tingting Liu, Linlin Lei +6
The strong chiral light-matter interaction is crucial for various important fields such as chiral optics, quantum optics, and biomedical optics, driving a quest for the extreme int…
