Journal ArticleDOI
Regenerative oscillation and four-wave mixing in graphene optoelectronics
Tingyi Gu,Nicholas Petrone,James F. McMillan,A. M. van der Zande,M. B. Yu,Guo-Qiang Lo,Dim-Lee Kwong,James Hone,Chee Wei Wong +8 more
TL;DR: In this article, the authors demonstrate the exceptionally high third-order nonlinearity of integrated mono-layer graphene-silicon hybrid optoelectronics, enabling ultralow power resonant optical bistability, self-induced regenerative oscillations, and coherent four-wave mixing, all at few femtojoule cavity recirculating energies.
Journal ArticleDOI
Switchable magnetic metamaterials using micromachining processes.
Weiming Zhu,Ai Qun Liu,Xuming Zhang,Din Ping Tsai,Tarik Bourouina,Jinghua Teng,Xinhai Zhang,H. C. Guo,H. Tanoto,Ting Mei,Guo-Qiang Lo,Dim-Lee Kwong +11 more
TL;DR: Micromachining technology has been developed for fabrication and actuation of micromechanical devices with switching frequencies up to the GHz level with a complementary approach to mechanically reconfi gure the metamaterial molecules.
Journal ArticleDOI
Microelectromechanical Maltese-cross metamaterial with tunable terahertz anisotropy.
Weiming Zhu,Ai Qun Liu,Ai Qun Liu,Tarik Bourouina,Din Ping Tsai,Din Ping Tsai,Jinghua Teng,Xinhai Zhang,Guo-Qiang Lo,Dim-Lee Kwong,Nikolay I. Zheludev,Nikolay I. Zheludev +11 more
TL;DR: A terahertz metamaterial with anisotropy tunable from positive to negative values is demonstrated based on the Maltese-cross pattern, which offers new opportunities for the development of teraHertz variable waveplates, tunable filters and polarimetry.
Journal ArticleDOI
A micromachined reconfigurable metamaterial via reconfiguration of asymmetric split-ring resonators
Yuan Hsing Fu,Yuan Hsing Fu,Ai Qun Liu,Weiming Zhu,Xuming Zhang,Din Ping Tsai,Jing Bo Zhang,Ting Mei,Jifang Tao,H. C. Guo,Xinhai Zhang,Jinghua Teng,Nikolay I. Zheludev,Guo-Qiang Lo,Dim-Lee Kwong +14 more
TL;DR: In this article, a micromachined reconfigurable metamaterial is presented, whose unit cell consists of a pair of asymmetric split-ring resonators (ASRRs); one is fixed to the substrate while the other is patterned on a movable frame.
Proceedings ArticleDOI
