Dirac-vortex modes beyond the continuum limit
Jiayu Fan, Jiusi Yu, Aoning Luo +7
Dirac-vortex modes (DVMs) in Kekule-modulated lattices provide a topological route to wave confinement and are commonly described by the continuum Jackiw-Rossi model, in which the…
Chiral Valley Edge States
Jian-Wei Liu, Gui-Geng Liu, Bo Zhang +7
Valleytronics has emerged as a promising paradigm, enabling comprehensive control of the valley degree of freedom (DoF) for energy-efficient and high-speed information processing.…
Overcoming Intrinsic Dispersion Locking for Achieving Spatio-Spectral Selectivity with Misaligned Bi-metagratings
Ze-Peng Zhuang, Xin Zhou, Hao-Long Zeng +6
Spatio-spectral selectivity, the capability to select a single mode with a specific wavevector (angle) and wavelength, is imperative for light emission and imaging. Continuous band…
Realization of chiral whispering gallery mode cavities enabled by photonic Chern insulators
Hao-Chang Mo, Zi-Xuan Gao, Xiao-Dong Chen +1
Recently, whispering gallery modes (WGMs) have attracted considerable attention due to their extensive applications in the development of on-chip microcavities, high-sensitivity se…
Experimental probe of band structures of bilayer valley photonic crystals
Xiang-Fei Guo, Jian-Wei Liu, Hong-Xiang Chen +3
Research on two-dimensional van der Waals materials has demonstrated that the layer degree of freedom can significantly alter the physical properties of materials due to the substa…
