متن کاملPropagating Surface Plasmons and Dispersion Relations for Nanoscale Multilayer Metallic-Dielectric Films
The study of propagating surface plasmons (PSPs) is an important aspect of the understanding of the interaction between light and metallic surfaces. One of the key concepts related to PSPs, is the dispersion relation. This relation is the basis for understanding of coupling of light to PSPs, by using special approaches to match the wavevector. Moreover, it can be used to predict the matching of...
متن کاملDetermining the terahertz optical properties of subwavelength films using semiconductor surface plasmons
By employing a combination of time-domain measurements and numerical calculations, we demonstrate that the semiconductor InSb supports a strongly confined surface plasmon SP in the terahertz frequency range. We show that these SPs can be used to enhance the light-matter interaction with dielectric layers above the semiconductor surface, thereby allowing us to detect the presence of polystyrene ...
متن کاملCoupling between semiconductor quantum dots and two-dimensional surface plasmons
When CdSe/CdS core/shell quantum dots QDs are dispersed onto a two-dimensional 2D textured Ag grating, their luminescent behavior is dramatically modified. Excited QDs can resonantly excite surface plasmon polaritons SPPs propagating along the modulated metallic surface. The measurements of PL spectra and time-resolved PL spectra clearly indicate the interaction between QDs and 2D SPPs. The ele...
متن کاملConformal surface plasmons propagating on ultrathin and flexible films.
Surface plasmon polaritons (SPPs) are localized surface electromagnetic waves that propagate along the interface between a metal and a dielectric. Owing to their inherent subwavelength confinement, SPPs have a strong potential to become building blocks of a type of photonic circuitry built up on 2D metal surfaces; however, SPPs are difficult to control on curved surfaces conformably and flexibl...
