Optical hysteresis is a fundamental phenomenon that can lead to optical bistability and high-
speed signal processing. Here, we present a theoretical and experimental study of the …

Plasmonics is a promising topic, studied from early 20th century, exploring phenomena
based on interaction between electromagnetic radiation and conduction electrons at metallic …

In a composite structure, which contains dielectric‐metal interface, waves of electric charge
densities can be initiated. The wave intensity decreases exponentially in adjacent media …

Since Kretschmann [1] proposed the use of evanescent waves to couple surface plasmons
with light, various chemical and biochemical sensors have been proposed and studied [2-5] …

Hydrocarbons are chemical compounds that consist entirely of carbon and hydrogen. These
substances are found everywhere given that they participate in the life cycle of living matter …

Almost six decades ago, in Romania a small group of physicists begun to study
chalcogenide compositions, motivated primarily by the desire to understand the phase …

Four‐layer surface plasmon resonance configuration that includes a thin film from As2S3 is
studied. By numerical calculations and experiment, it is established that the shape of the …

The surface plasmon resonance (SPR) four layers configuration that contains prism of BK7-
gold metal film-As2Se3 waveguide-air was realized. As 2 Se 3 thin films with low roughness …

In this paper we present theoretical and experimental results regarding the analysis of
optimum conditions to couple the light within a BK7-Au-As2S3-Air plasmonic compound. We …
