Nanophotonics is an important branch of modern optics dealing with light–matter interaction
at the nanoscale. Nanoparticles can exhibit enhanced light absorption under illumination by …

Surface-enhanced Raman scattering (SERS) sensors are very powerful analytical tools for
the highly sensitive detection of chemical and biological molecules. Substantial efforts have …

We present metal-dielectric metasurfaces fabricated from metal periodical nanograting
deposited on a dielectric substrate. The metasurface consists of a modulated dielectric …

Metal-dielectric micro/nano-composites have surface plasmon resonances in visible and
near-infrared domains. Excitation of coupled metal-dielectric resonances is also important …

A composite structure based on a Kretschmann structure loaded with silver nano-cube is
proposed. A 442-nm laser was used to excite surface plasmons in the composite structure …

A method for phase identification (MPI) in two-dimensional (2D) condensable systems is
proposed on the basis of the analysis of the Voronoi cells' characteristics. A simple algorithm …

We present here the amplification of the surface-enhanced Raman scattering (SERS) signal
of nanodisks on a gold film for SERS sensing of small molecules (thiophenol) with an …

The appearance of the double-resonance substrate has promoted the application of surface-
enhanced Raman scattering (SERS). By controlling the frequencies of the double …

When decorated with plasmonic nanoparticles, pulled optical nanofibers are compatible with
plasmonic techniques enabling the ability to probe microenvironments with high spatial and …

In this paper, we propose a reconfigurable two-dimensional photonic crystal (PC) made from
a new ultralow loss phase change material for detecting and imaging applications of surface …
