The subject of light transmission through optically thin metal films perforated with arrays of subwavelength nanoholes has recently attracted significant attention. In this work, we present experimental and calculated results on optical transmission/reflec ...
We numerically study the effect of structural asymmetry in a plasmonic metamaterial made from gold nanowires. It is reported that optically inactive (i.e., optically dark) particle plasmon modes of the symmetric wire lattice are immediately coupled to the ...
This work includes the fabrication of plasmonic nanostructures as well as the investigation of their optical properties in the near-field and in the farfield. As expressed in the title of this thesis the focus lies in the subwavelength confinement and enha ...
This work focuses on trapping subwavelength objects using resonant plasmonic structures. Trapping entities include latex spheres, living cells and metallic particles; the plasmonic structures involved include subwavelength disks, subwavelength apertures, a ...
A novel local illumination scheme for optical lithography is proposed. It is based on the excitation of a surface plasmon on a metal film incorporated into a polymer light coupling mask for contact lithography. The electromagnetic field associated with the ...
The introduction of high-throughput and high-resolution nanofabrication techniques operating at low cost and low complexity is essential for the advancement of nanoplasmonic and nanophotonic fields In this paper. we demonstrate a novel fabrication approach ...
Plasmonics, by localizing light below sub-diffraction limit and enhancing local field intensities, is enabling exciting possibilities in bio-detection field. In this talk, I will present novel plasmonic systems for ultrasensitive vibrational nanospectrosco ...
We demonstrate an efficient numerical scheme for the computation of the excitonic optical response of actual GaAs/AlGaAs quantum wire structures including a large set of relevant effects; structural, valence band-mixing, dielectric and many-body effects ca ...
