Broadband Multifocal Conic-Shaped Metalens
Yanjun Bao, Qiao Jiang, Yimin Kang +2
Multifocal lens, which focus incident light at multiple foci, are widely used in imaging systems and optical communications. However, for the traditional design strategy, it combin…
Active control of surface plasmon resonance in MoS2-Ag hybrid nanostructures
Shuai Zu, Bowen Li, Yongji Gong +2
Molybdenum disulfide (MoS2) monolayers have attracted much attention for their novel optical properties and efficient light-matter interactions. When excited by incident laser, the…
Revealing the spin optics of conics
Yanjun Bao, Shuai Zu, Wei Liu +3
Ellipse and hyperbola are two well-known curves in mathematics with numerous applications in various fields, but their properties and inherent differences in spin optics are less u…
Fano Resonances of Plasmonic Nanodisk
Zheyu Fang, Junyi Cai, Zhongbo Yan +2
The Fano resonance of a single symmetry broken Ag nanodisk under a normal incidence was investigated by using finite-difference time-domain (FDTD) simulations. The asymmetry line s…
