We study a structure consisting of a gold disk array, an SiO2 spacer, and a gold film. We study the effect of spacer thickness on the anti-crossing between localized plasmons and surface plasmon polaritons.
We demonstrate the fabrication of plasmonic nanostructures (rings, split rings, and other structures) by a process involving molding by soft lithography, thin film deposition, and mechanical sectioning (nanoskiving). This unique process is highly parallelizable and allows for the fabrication of nanostructures of multiple materials in the same plane and very high aspect ratio structures. We characterize...
Fundamentals of the three-dimensional spatial harmonic analysis (SHA) approach are reviewed, and the advantages of a fast-converging formulation versus the initial formulation are emphasized with examples using periodic plasmonic nanostructures.
We study the effects of nanodots on surface plasmons and field enhancement in nano-pillar antenna array (NPA). The NPA's nanodots have slight effect on surface plasmon resonance wavelength, but increase field enhancement by two orders of magnitude.
Subwavelength gold nanoparticles array were fabricated on optical fibers tip with sensitivity of 195nm/RIU has been demonstrated. Nemetic liquid crystal has been used for enhancing sensitivity of LSPR-based detection of binding events.
