Active Tuning of Resonant Lattice Kerker Effect
Lei Xiong, Hongwei Ding, Yuanfu Lu +1
The Kerker effect has been generalized in nanophotonics and meta-optics, and has recently been of great interest by relating to various fascinating functionalities such as scatteri…

Narrow quadrupolar surface lattice resonances and band reversal in vertical metal-insulator-metal gratings
Xinyu Fang, Lei Xiong, Jianping Shi +2
We report narrow quadrupolar surface lattice resonances (SLRs) under normal incidence, and the observation, for the first time, of the band reversal effect of SLRs supported by a v…

Mirror-backed dielectric metasurface sensor with ultrahigh figure of merit based on super-narrow Rayleigh anomaly
Yonghang Wang, Lei Xiong, Ming Tian +1
Plasmonic nanostructures with large local field enhancement have been extensively investigated for sensing applications. However, the quality factor and thus the sensing figure of…
