Nontrivial topology in one- and two-dimensional asymmetric systems with chiral boundary states
Yunlin Li, Yufu Liu, Xuezhi Wang +2
Symmetry plays an important role in the topological band theory. In contrary, study on the topological properties of the asymmetric systems is rather limited, especially in higher-…

Enhancement of spin-orbit interaction and nearly perfect spin-conversion by 1D photonic crystal with the anisotropic defect layer
Xianjun Wang, Yufu Liu, Yunlin Li +2
Although photon spin-orbit interaction (SOI) has been extensively studied, the vortex-conversion efficiency and the enhancement of spin Hall effect in abnormal modes in SOI remain…

Dual-polarization huge photonic spin Hall shift and deep-subwavelength sensing based on topological singularities in one-dimensional photonic crystals
Yufu Liu, Xianjun Wang, Yunlin Li +6
Although several efforts have been taken to enhance the photonic spin Hall shift in deep-subwavelength region, according to effective medium theory, the fundamental confliction bet…
