Omnidirectional photonic chiral flatband in nonlocal membrane metasurfaces
Baohe Zhang, Jumin Qiu, Meng Qin +7
Omnidirectional flat-band resonances, characterized by an enhanced photonic density of states and inherent angular robustness, are highly sought-after in integrated nanophotonic de…

MoS2-based optical bistability in silver-Bragg reflector multilayer structure at visible light band
Songqing Tang, Mengjiao Ren, Zhiheng Li +2
In this paper, we present a theoretical analysis of the optical bistability in a metallic silver-Bragg reflector structure by embedding bilayer MoS2 at the visible band. The nonlin…
