Engineering nanostructures with exceptionally high-Q resonances mediated by the Fano-
type hybridization between discrete states associated with the periodicity of the structure and …

Conventional optical tweezers, formed at the diffraction-limited focus of a laser beam, have
become a powerful and flexible tool for manipulating micrometre-sized objects. Extending …

Broadband electromagnetic wave absorbers are highly desirable in numerous applications
such as solar-energy harvesting, thermo-photovoltaics, and photon detection. The aim to …

We demonstrate an improvement by more than 1 order of magnitude of the figure of merit
(FoM) of plasmonic nanoparticle sensors by means of the diffractive coupling of localized …

We present nonlinear-optical four-wave mixing (4WM) at coupled gold nanoparticles. By
decreasing the interparticle distance from large separation to touching contact, the 4WM …

In this study, we report on ultrasensitive protein detection with lithographically prepared
plasmonic nanostructures. We have engineered optical nanosensors by the combined …

We present spatially resolved spectral mode mapping of resonant plasmon gap antennas
using two-photon luminescence microspectroscopy. The obtained maps are in good …

Metamaterial-based nano-scale absorbers have been becoming very popular in the modern
era due to efficiently absorbing solar radiation to revamp the performance characteristics of …

We report that plasmonic nanoantennas made by DNA origami can be used as reliable and
efficient probes for surface-enhanced Raman spectroscopy (SERS). The nanoantenna is …

This review focuses on the optical properties and device applications of deterministic
aperiodic media generated by mathematical rules with spectral features that interpolate in a …
