چکیده
Orbital angular momentum of photons is explored to study the spatial mode properties of the plasmon-assisted transmission process. We found that photons carrying different orbital angular momenta have different transmission efficiencies, while the coherence between these spatial modes can be preserved.

Plasmon modes in single gold nanodiscs.
Optical properties of single gold nanodiscs were studied by scanning near-field optical microscopy. Near-field transmission spectra of a single nanodisc exhibited multiple plasmon resonances in the visible to near-infrared region. Near-field transmission images observed at these resonance wavelengths show wavy spatial features depending on the wavelength of observation. To clarify physical pict...
متن کاملLattice-Plasmon Quantum Features
in this work, some of the lattice plasmon quantum features are examined. Initially, the interaction of the far-field photonic mode and the nanoparticle plasmon mode is investigated. We probe the optical properties of the array plasmon that are dramatically affected by the array geometry. It is notable to mention that the original goal of this work is to examine the quantum feature of the array ...
متن کاملPlasmonic external cavity laser refractometric sensor.
Combining the high sensitivity properties of surface plasmon resonance refractive index sensing with a tunable external cavity laser, we demonstrate a plasmonic external cavity laser (ECL) for high resolution refractometric sensing. The plasmonic ECL utilizes a plasmonic crystal with extraordinary optical transmission (EOT) as the wavelength-selective element, and achieves single mode lasing at...
متن کاملOn-chip surface-based detection with nanohole arrays.
A microfluidic device with integrated surface plasmon resonance (SPR) chemical and biological sensors based on arrays of nanoholes in gold films is demonstrated. Widespread use of SPR for surface analysis in laboratories has not translated to microfluidic analytical chip platforms, in part due to challenges associated with scaling down the optics and the surface area required for common reflect...
متن کاملMapping plasmons in nanoantennas via cathodoluminescence
We analyze cathodoluminescence (CL) emission from silver nanorod antennas induced by energetic electron beams. The dependence of the emission spectra on particle morphology and electron energy is explored by means of full electromagnetic calculations based on the boundary element method (BEM). We present light-emission image maps obtained by using a light detection system that is incorporated i...
