Journal ArticleDOI
Disposable plasmonic plastic SERS sensor
Swe Zin Oo,Ruiqi Y. Chen,Samuli Siitonen,Ville Kontturi,David Eustace,Jarkko Tuominen,Sanna Aikio,Martin D. B. Charlton +7 more
TL;DR: Successful transfer from silicon to plastic base platform of an optimized SERS substrate design which provides 8 times improvement in sensitivity for a Benzenethiol test molecule compared to standard production Klarite is reported.
Journal ArticleDOI
Photonic crystal and quasi-crystals providing simultaneous light coupling and beam splitting within a low refractive-index slab waveguide
Jingxing Shi,Michael E. Pollard,Cesar A. Angeles,Ruiqi Y. Chen,James C. Gates,Martin D. B. Charlton +5 more
TL;DR: This paper presents a photonic crystal device which performs both tasks simultaneously and is able to couple light at normal incidence and near normal incidence, and shows how to optimize the lattice constant to achieve efficient phase matching between incident and coupled mode wave vectors.
Journal ArticleDOI
Contact resistance measurement of Ge 2 Sb 2 Te 5 phase change material to TiN electrode by spacer etched nanowire
Ruomeng Huang,Kai Sun,Kian Shen Kiang,Ruiqi Y. Chen,Yudong Wang,Behrad Gholipour,Daniel W. Hewak,C.H. de Groot +7 more
TL;DR: In this paper, the contact resistance between GST phase change material and TiN metal electrodes was investigated in both crystalline and amorphous states, and it was found that contact resistance plays a dominant role in the total resistance of GST memory device in both crystal and non-crystalline states.
Journal ArticleDOI
Chi 3 dispersion in planar tantalum pentoxide waveguides in the telecommunications window
TL;DR: The observation of efficient third-harmonic generation in Ta2O5 waveguides in the telecoms window reveals the potential of this material system in high-speed integrated nonlinear optical switches.
Proceedings ArticleDOI
Optimization of SERS enhancement from nanostructured metallic substrate based on arrays of inverted rectangular pyramids and investigation of effect of lattice non-symmetry
Swe Zin Oo,Martin D. B. Charlton,David Eustace,Ruiqi Y. Chen,Stuart Pearce,Michael E. Pollard +5 more
TL;DR: In this article, the effect of aspect ratio on surface-enhanced Raman scattering (SERS) signal enhancement has been investigated using a new rectangular lattice arrangement and investigate the effect on SERS enhancement factor.
