Switchable Ultrathin Quarter-wave Plate in Terahertz Using Active Phase-change Metasurface.
Dacheng Wang,Lingchao Zhang,Yinghong Gu,Muhammad Qasim Mehmood,Yandong Gong,Amar Srivastava,L. K. Jian,Thirumalai Venkatesan,Cheng-Wei Qiu,Minghui Hong +9 more
TL;DR: This work reveals the feasibility to realize tunable/active and extremely low-profile polarization manipulation devices in the terahertz regime through the incorporation of such phase-change metasurfaces, enabling novel applications of ultrathin terAhertz meta- devices.
Journal ArticleDOI
Terahertz All-Dielectric Magnetic Mirror Metasurfaces
Zhijie Ma,Stephen M. Hanham,Pablo Albella,Binghao Ng,Hsiao Tzu Lu,Yandong Gong,Stefan A. Maier,Minghui Hong +7 more
TL;DR: In this article, an all-dielectric metasurface operating in the terahertz band was demonstrated, which is capable of engineering a reflected beam's spatial properties with high efficiency.
Journal ArticleDOI
An ultrathin terahertz quarter-wave plate using planar babinet-inverted metasurface
TL;DR: The design and experimental demonstration of an ultrathin (0.29λ) terahertz quarter-wave plate based on planar babinet-inverted metasurface based on an analytical model is presented, which opens up avenues for new functional teraHertz devices design.
Journal ArticleDOI
All-dielectric planar chiral metasurface with gradient geometric phase.
TL;DR: A planar chiral all-dielectric metasurface is proposed that exhibits giant circular dichroism and transmission asymmetry over 0.8 for circularly polarized lights with negligible loss, without bringing in bianisotropy or violating reciprocity.
Journal ArticleDOI
High-energy laser pulse with a submegahertz repetition rate from a passively mode-locked fiber laser
TL;DR: Without any discrete dispersion-compensation components or conventional spectral filters, the SESAM works together with the strongly chirped pulse and the nonlinearity induced spectrum broadening to perform a filtering-equivalent function, thus stabilizing the mode locking.
