60-nm-span wavelength-tunable vortex fiber laser with intracavity plasmon metasurfaces
Lili Gui, Chuanshuo Wang, Fei Ding +5
Wavelength-tunable vortex fiber lasers that could generate beams carrying orbital angular momentum (OAM) hold great interest in large-capacity optical communications. The wavelengt…
Tungsten based Anisotropic Metamaterial as an Ultra-broadband Absorber
Yinyue Lin, Yanxia Cui, Fei Ding +4
The trapped rainbow effect has been mostly found on tapered anisotropic metamaterials (MMs) made of low loss noble metals, such as gold, silver, etc. In this work, we demonstrate t…
High-performance THz metamaterial absorber
Jianfei Zhu, Zhaofeng Ma, Wujiong Sun +4
We demonstrated an ultra-broadband, polarization-insensitive and wide-angle metamaterial absorber for terahertz (THz) frequencies using arrays of truncated pyramid unit structure m…
Plasmonic and Metamaterial Structures as Electromagnetic Absorbers
Yanxia Cui, Yingran He, Yi Jin +6
Electromagnetic absorbers have drawn increasing attention in many areas. A series of plasmonic and metamaterial structures can work as efficient narrow band absorbers due to the ex…
