Broadband switchable terahertz half-/quarter-wave plate based on VO2-metal hybrid metasurface with over/underdamped transition
Xiaoqing Luo, Fangrong Hu, Guangyuan Li
Dynamically switchable half-/quarter-wave plates have recently been the focus in the terahertz regime. Conventional design philosophy leads to multilayer metamaterials or narrowban…
Dynamically reversible and strong circular dichroism based on Babinet-invertible chiral metasurfaces
Xiaoqing Luo, Fangrong Hu, Guangyuan Li
We propose a Babinet-invertible chiral metasurface for achieving dynamically reversible and strong circular dichroism (CD). The proposed metasurface is composed of VO-metal hyb…
Nonvolatile, reconfigurable and narrowband mid-infrared filter based on surface lattice resonance in phase-change GeSbTe
Xingzhe Shi, Changshui Chen, Songhao Liu +1
We propose a nonvolatile, reconfigurable, and narrowband mid-infrared bandpass filter based on surface lattice resonance in phase-change material Ge2Sb2Te5 (GST). The proposed filt…
Two-dimensional plasmonic waveguides for nanolasing and four-wave mixing
Guangyuan Li, Stefano Palomba, C. Martijn de Sterke
Plasmonic waveguides are an essential element of nanoscale coherent sources, including nanolasers and four-wave mixing (FWM) devices. Here we report how the design of the plasmonic…
Necessary conditions for out-of-plane lattice plasmons in nanoparticle arrays
Gordon Han Ying Li, Guangyuan Li
Out-of-plane lattice plasmons (OLPs) supported by metallic nanoparticle arrays are promising for diverse applications due to their remarkably narrow linewidths and significant enha…
Fourier single-pixel imaging in the terahertz regime
Rongbin She, Wenquan Liu, Yuanfu Lu +2
We demonstrate Fourier single-pixel imaging in the terahertz regime. The experimental system is implemented with a photo-induced coded aperture setup, where a monolayer graphene on…
