Triple-band tunable perfect terahertz metamaterial absorber with liquid crystal
TL;DR: In this paper, a triple-band tunable perfect terahertz metamaterial absorber (TMA) was proposed, which is composed of a planar metallic disk resonator array above a conductive ground plane separated with liquid crystal (LC) mixture.
Journal ArticleDOI
Ultrasensitive Tunable Terahertz Sensor With Graphene Plasmonic Grating
Fei Yan,Li Li,Ruoxing Wang,Hao Tian,Jianlong Liu,Jian-Qiang Liu,Fengjun Tian,Jianzhong Zhang +7 more
TL;DR: In this article, the authors proposed an ultrasensitive tunable terahertz (THz) sensor which consists of single-layer graphene-based gratings integrated with a Fabry-Perot cavity through numerical simulation.
Journal ArticleDOI
Design and numerical analysis of a THz square porous-core photonic crystal fiber for low flattened dispersion, ultrahigh birefringence.
TL;DR: A kind of square porous-core photonic crystal fiber for polarization-maintaining terahertz (THz) wave guidance is proposed, and ultrahigh birefringence and low effective material loss (EML) can be achieved simultaneously.
Journal ArticleDOI
Gaseous ammonia fluorescence probe based on cellulose acetate modified microstructured optical fiber
TL;DR: In this paper, a novel fluorescent ammonia gas probe based on microstructured optical fiber (MOF) which is modified with eosin-doped cellulose acetate film was fabricated by liquid fluxion coating process.
Journal ArticleDOI
Compact self-Q-switched Tm:YLF laser at 1.91 μm
TL;DR: In this paper, self-Q-switching operation in a diode-pumped Tm:YLF bulk laser by exploiting saturable re-absorption under the quasi-three-level regime was demonstrated experimentally with 1.91μm in fundamental mode.
