Wave morphing and flat-top ground states in photonics systems driven by artificial gauge fields
Peishen Li, Xiaoyu Zhang, Feifan Wang +3
In quantum physics, classical optics, and many other wave systems, wave confinement in a potential well is associated with discrete oscillatory states, and the ground state is typi…
Orbital chiral lasing in twisted bilayer metasurfaces
Mingjin Wang, Nianyuan Lv, Zixuan Zhang +11
Chirality is a fundamental concept in physics that underpins various phenomena in nonlinear optics, quantum physics, and topological photonics. Although the spin of a photon natura…
Chiral emission of vortex microlasers enabled by collective modes of guided resonances
Ye Chen, Mingjin Wang, Jiahao Si +8
Vortex lasers have attracted substantial attention in recent years owing to their wide array of applications such as micromanipulation, optical multiplexing, and quantum cryptograp…
Observation of Berry curvature in non-Hermitian system from far-field radiation
Xuefan Yin, Ye Chen, Xiaoyu Zhang +3
Berry curvature that describes local geometrical properties of energy bands can elucidate many fascinating phenomena in solid-state, photonic, and phononic systems, given its conne…
