Optical sensors are widely used for refractive index measurement in chemical, biomedical,
and food processing industries. Due to specific field distribution of the resonances, optical …

Plasmonic metamaterials are artificial materials typically composed of noble metals in which
the features of photonics and electronics are linked by coupling photons to conduction …

We present an experimental analysis of the plasmonic scattering properties of gold
nanoparticles controllably placed nanometers away from a gold metal film. We show that the …

Strong coupling between two resonance modes leads to the formation of new hybrid modes
exhibiting disparate characteristics owing to the reversible exchange of information between …

We report a surface-enhanced Raman scattering (SERS) substrate with plasmon
resonances at both excitation and Stokes frequencies. This multilayer structure combines …

The interaction between localized and propagating surface plasmons is investigated in a
structure consisting of a two-dimensional periodic gold nanoparticle array, an Si O 2 spacer …

Polarization-controlled excitation of plasmonic modes in nanometric Au particle-on-film gaps
is investigated experimentally using single-particle dark-field spectroscopy. Two distinct …

The localized surface plasmon resonance (LSPR) spectrum associated with a gold
nanoparticle (NP) coupled to a gold film exhibits extreme sensitivity to the nanogap region …

Plasmonic nanoantennas, which can efficiently convert light from free space into sub-
wavelength scale with the local field enhancement, are fundamental building blocks for …

Subwavelength holes are one of the most important structures in nanophotonics, providing a
useful geometry for nanosensing and giving rise to extraordinary transmission when …
