Abstract:
Since Ebbesen's seminal work in 1998 observing extraordinary optical transmission (EOT) through nanohole arrays, much research has focused on the role of surface plasmon polaritons (SPPs) in EOT. While the energy and momentum conditions have become clear, no consensus has been reached on the role of incident light polarization. This study presents a simple model that captures Bloch-SPP excitation, including the role of polarization, in general periodic plasmonic structures. Our model predicts that under certain conditions polarization conversion should occur in EOT light transmitted through th

Abstract:
This dissertation contains analytical and numerical studies of nonlinear surface-plasmon polaritons (SPPs). In our studies, we consider SPP propagation at the interface between a noble metal with a cubic optical nonlinearity and an optically linear dielectric. We first consider a sum-frequency generation process during the nonlinear interaction, where a nonlinear polarization with tripled frequency is generated from the incident fundamental SPP. Using the non-depletion approximation, the solution of the nonlinear wave equation shows a third harmonic generation process from the incident

We have developed a general theory of the plasmonic enhancement of many-body phenomena resulting in a closed expression for the surface plasmon-dressed Coulomb interaction. It is shown that this interaction has a resonant nature. We have also demonstrated that renormalized interaction is a long-ranged interaction whose intensity is considerably increased compared to bare Coulomb interaction over the entire region near the plasmonic nanostructure. We illustrate this theory by re-deriving the mirror charge potential near a metal sphere as well as the quasistatic potential behind the so-called pe

Abstract:
Surface plasmon-polaritons are optical surface waves formed through the interaction of photons with free electrons at the surface of metals. They offer interesting applications in a broad range of scientific fields such as physics, chemistry, biology, and material science. However, many of such applications face limitations imposed by the high propagation losses of these waves at visible and near-infrared wavelengths, which result mainly from power dissipation in the metal. In principle, the propagation losses of surface plasmon-polaritons can be compensated through optical amplification. Th

Hlavním předmětem této diplomové práce jsou elektromagnetické simulace pomocí metody konečných prvků (FEM) k vyšetření vlivu grafenu na hrotem zesílenou Ramanovu spektroskopii (TERS) a povrchem zesílenou infračervenou absorpční spektroskopii (SEIRA) a k prozkoumání citlivosti sondy skenovacího optického mikroskopu blízkého pole (SNOM) ke složkám elektromagnetického pole v závislosti na parametrech sondy (průměru apertury v pokovení). Nejprve je proveden výpočet TERS systému složeného ze stříbrného hrotu nacházejícího se nad zlatým substrátem s tenkou vrstvou molekul, jehož účelem je porozumění

Abstract:
Exziton-Polaritonen in Mikrokavitäten sind Quasi-Teilchen, die unter bestimmten physikalischen Konditionen kondensieren und damit in einen energetisch gleichen, gemeinsamen makroskopischen Quantenzustand (MQZ) übergehen können. Exziton-Polariton-Kondensate können mithilfe von akustischen Oberflächenwellen moduliert werden, um ihre Eigenschaften zu verändern. Dies ist insbesondere von großer Relevanz für zukünftige Anwendungen. In dieser Arbeit wurden die Struktur sowie die Dynamik der Exziton-Polariton-Kondensate in den durch die akustischen Oberflächenwellen erzeugten quadratischen Gittern

Abstract:
O confinamento da luz em escala nanométrica, em especial para estruturas metálicas, é conferido graças à ação coletiva dos elétrons livres desses materiais que ao entrarem em ressonância com a frequência da radiação incidente geram campos intensos o suficiente para permitir que uma parcela da luz atravesse as cavidades que formam as estruturas, desafiando os limites clássicos da óptica impostos pela teoria escalar da difração. Designa-se a tal ação coletiva dos elétrons na literatura como plasmons polaritons de superfície, ou SPP da sigla em inglês para Surface Plasmon Polariton, conceito há m
