Enhancement of Long-Range Surface Plasmon Excitation, Dynamic Range and Figure of Merit Using a Dielectric Resonant Cavity

open access: yesSensors, 2018
In this paper, we report a theoretical framework on the effect of multiple resonances inside the dielectric cavity of insulator-insulator-metal-insulator (IIMI)-based surface plasmon sensors.

High‐Efficiency Miniaturized Spoof Plasmonic Waveguide Filter from Direct Current to Millimeter‐Wave Frequency

open access: yesAdvanced Photonics Research, 2022
Spoof surface plasmon polaritons (SSPPs) are highly confined electromagnetic (EM) surface waves in microwave and millimeter‐wave frequencies, mimicking the surface plasmon polaritons (SPPs) in the optical frequency, which have many potential applications

Composite Structure Based on Gold-Nanoparticle Layer and HMM for Surface-Enhanced Raman Spectroscopy Analysis

open access: yesNanomaterials, 2021
Hyperbolic metamaterials (HMMs), supporting surface plasmon polaritons (SPPs), and highly confined bulk plasmon polaritons (BPPs) possess promising potential for application as surface-enhanced Raman scattering (SERS) substrates.

Universal optical transmission features in periodic and quasiperiodic hole arrays [PDF]

open access: yes, 2008
We investigate the influence of array order in the optical transmission properties of subwavelength hole arrays, by comparing the experimental spectral transmittance of periodic and quasiperiodic hole arrays as a function of frequency.

Ultrasensitive probing of plasmonic hot electron occupancies

open access: yesNature Communications, 2022
Experimental evidence is given that upon the optical excitation of surface plasmon polaritons, a nonthermal electron population appears in the topmost domain of the plasmonic film directly coupled to the local fields.

Plasmon polaritons in photonic superlattices containing a left-handed material [PDF]

open access: yes, 2009
We analyze one-dimensional photonic superlattices which alternate layers of air and a left-handed material. We assume Drude-type dispersive responses for the dielectric permittivity and magnetic permeability of the left-handed material.

Spatio-temporal second-order quantum correlations of surface plasmon polaritons

open access: yes, 2015
We present an experimental methodology to observe spatio-temporal second-order quantum coherence of surface plasmon polaritons which are emitted by nitrogen vacancy color centers attached at the apex of an optical tip.
