Journal ArticleDOI
Ultra high quality factor one dimensional photonic crystal/photonic wire micro-cavities in silicon-on-insulator (SOI)
TL;DR: Experimental results on photonic crystal/photonic wire micro-cavity structures that demonstrate further enhancement of the quality-factor (Q-factor)--up to approximately 149,000--in the fibre telecommunications wavelength range are presented.
Journal ArticleDOI
All-optical switching in silicon-on-insulator photonic wire nano–cavities
M. Belotti,Matteo Galli,Dario Gerace,Lucio Claudio Andreani,Giorgio Guizzetti,Ahmad Rifqi Md Zain,Nigel P. Johnson,Marc Sorel,Richard M. De La Rue +8 more
TL;DR: All-optical switching with a very low power is demonstrated on photonic crystal wire nano-cavities on silicon-on-insulator with large quality factors and high transmission in the telecom range.
Journal ArticleDOI
Tapered Photonic Crystal Microcavities Embedded in Photonic Wire Waveguides With Large Resonance Quality-Factor and High Transmission
TL;DR: In this article, a single-row photonic crystal (PhC) embedded in a 500nm-wide photonic wire waveguide was used to construct a microcavity that exhibits simultaneously high transmission and large resonance quality-factor.
Journal ArticleDOI
Metamaterial absorber comprising chromium-gold nanorods-based columnar thin films
Masih Ghasemi,Pankaj Kumar Choudhury,Muhammad Abuzar Baqir,Mohd Ambri Mohamed,Ahmad Rifqi Md Zain,Burhanuddin Yeop Majlis +5 more
TL;DR: In this article, the absorption characteristics of complex medium structures having metasurfaces comprised of columnar nanorods of gold were investigated, and the results showed that the absorber having elliptical gold nanors yields a better performance than the one with circular nanorod in terms of the magnitude/smoothness of the absorption peaks.
Proceedings ArticleDOI
Copper-graphene SPR-based biosensor for urea detection
Fairus Atida Said,P. Susthitha Menon,Mohd Nuriman Nawi,Ahmad Rifqi Md Zain,Azman Jalar,Burhanuddin Yeop Majlis +5 more
TL;DR: In this paper, the copper-graphene surface plasmon resonance (SPR)-based biosensor was investigated by considering the high adsorption efficiency of graphene, which is used to prevent Cu from oxidation and enhance the reflectance intensity.
