Xiao, Jing (author), Wei, Qi-Qin (author), Yang, Duo Guo (author), Zhang, Ping (author), He, Ning (author), Zhang, Kouchi (author), Chen, Xian Ping (author)The slot waveguide has attracted considerable attention because of its ability to confine and guide electromagnetic energy at the subwavelength scale beyond the diffraction limit. We propose a novel terahertz slot waveguide structure to achieve a better tradeoff between propagation length and field confinement capacity, the novel waveguide...journal article 2017

Xu, Man (author), Wei, S. (author), Zlatanova, S. (author), Zhang, Ruiju (author)At present, 87 % of people's activities are in indoor environment; indoor navigation has become a research issue. As the building structures for people's daily life are more and more complex, many obstacles influence humans' moving. Therefore it is essential to provide an accurate and efficient indoor path planning. Nowadays there are many...conference paper 2017

Li, X. (author), Wei, L. (author), Poelma, René H. (author), Vollebregt, S. (author), Wei, J. (author), Urbach, Paul (author), Sarro, Pasqualina M (author), Zhang, Kouchi (author)This paper presents a tuneable binary amplitude Fresnel lens produced by wafer-level microfabrication. The Fresnel lens is fabricated by encapsulating lithographically defined vertically aligned carbon nanotube (CNT) bundles inside a polydimethyl-siloxane (PDMS) layer. The composite lens material combines the excellent optical absorption...journal article 2016

Xiao, Jing (author), Wei, Qi-Qin (author), Yang, Daoguo (author), Zhang, Ping (author), He, Ning (author), Zhang, Kouchi (author), Ren, Tian-Ling (author), Chen, Xian-Ping (author)The emerging field of nanophotonics requires plasmonic devices to be fully compatible with semiconductor fabrication techniques. However, very few feasible practical structures exist at present. Here, we propose a CMOS-compatible hybrid plasmonic slot waveguide (HPSW) with enhanced field confinement. Our simulation results show that the HPSW...journal article 2016

Wei, J. (author), Ye, H. (author), Van Zeijl, H.W. (author), Sarro, P.M. (author), Zhang, G.Q. (author)A micro-electro-mechanical-system (MEMS) based, temperature triggered, switch is developed as a cost-effective solution for smart cooling control of solid-state-lighting systems. The switch (1.0x0.4 mm2) is embedded in a silicon substrate and fabricated with a single-mask 3D micro-machining process. The device switches on at a designed...journal article 2012
