Non-reciprocal optical reflection from a bidimensional array of subwavelength holes in a metallic film [PDF]
, 2004 Using simulations and theoretical arguments we investigate the specular reflection of a perforated gold film deposited on a glass substrate. A square lattice of cylindrical holes is assumed to produce the periodic lateral corrugation needed to hybridize ...

Sol-Gel Thin Films for Plasmonic Gas Sensors
Sensors, 2015 Plasmonic gas sensors are optical sensors that use localized surface plasmons or extended surface plasmons as transducing platform. Surface plasmons are very sensitive to dielectric variations of the environment or to electron exchange, and these effects

Quantum Dot-Induced Blue Shift of Surface Plasmon Spectroscopy
Nanomaterials, 2022 We experimentally demonstrate the spectral blue shift of surface plasmon resonance through the resonant coupling between quantum dots (QDs) and surface plasmons, surprisingly in contrast to the conventionally observed red shift of plasmon spectroscopy ...

Surface Plasmons in Silicon Nanowires
Advanced Photonics Research, 2021 Plasmon resonances (PRs) in metallic nanostructures have been extensively studied, whereas reports on PR in silicon nanowires (Si NWs) are very few, partial, and they refer to structures larger than 100 nm.

Gate-tunable plasmons in mixed-dimensional van der Waals heterostructures
Nature Communications, 2021 Surface plasmons have unique physical properties that make them also interesting for technology. Here, the authors observe plasmons in mixed-dimensional heterostructures that can be highly modulated with electrostatic gating, which may be explained by ...
