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

, 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.

Extremely short-length surface plasmon resonance sensors [PDF]

, 2008
The impact of the system design on the control of coupling between planar waveguide modes and surface plasmon polaritons (SPP) is analyzed. We examine how the efficiency of the coupling can be enhanced by an appropriate dimensioning of a multi-layer ...

Ultrasensitive probing of plasmonic hot electron occupancies

Nature 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.

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

Nanomaterials, 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]

, 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.

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

Advanced 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

All-angle negative refraction of highly squeezed plasmon and phonon polaritons in graphene-boron nitride heterostructures

, 2017
A fundamental building block for nanophotonics is the ability to achieve negative refraction of polaritons, because this could enable the demonstration of many unique nanoscale applications such as deep-subwavelength imaging, superlens, and novel guiding.

Circular‐Polarization‐Sensitive Organic Photodetectors with a Chiral Nanopatterned Electrode Inverse‐Designed by Genetic Algorithm

Advanced Functional Materials, EarlyView.
A chiral photodetector capable of selectively distinguishing left‐ and right‐handed circularly polarized light is experimentally demonstrated. The device, which features a nanopatterned electrode inverse‐designed by a genetic algorithm within a metal–dielectric–metal nanocavity that incorporates a vacuum‐deposited small‐molecule multilayer, exhibits ...
