ABSTRACT
Far-infrared electromagnetic radiation is emitted by coherent plasmon oscillations in bulk (111) InSb. The oscillations are excited by near-infrared ultrashort laser pulses and characterized as a function of temperature. The coherent plasmon frequency is determined by the intrinsic electron concentration and donor doping density. The amplitude of the oscillations decreases with increasing temperature due to a weakening of the photo-Dember starting mechanism.

    Surface plasmon polaritons, propagating bound oscillations of electrons and light at a metal surface, have great potential as information carriers for next-generation, highly integrated nanophotonic devices. Since the term ‘active plasmonics’ was coined in 2004, a number of...

    The theory and practical applications of very slow (antisymmetric) optical plasmons are described. These plasmons can exist on thin metal films and filaments and (as standing waves) on metal spheres and ellipsoids. The material presented here extends the conventional concepts of electromagnetic...

    We report a significantly enhanced photon drag effect (PDE) in a Au thin film at the surface plasmon resonance when the film is mounted in the Kretschmann-Raether geometry. The PDE is observed in the form of an electrical direct current induced by optical excitation. We discuss a model to...

    We propose and experimentally verify a bidirectional bending splitter of designer surface plasmons which is composed of two metallic gratings of trapezoid grooves. A metal wire is used to excite the designer surface plasmons propagating along the gratings. A full-wave numerical method has been...

    Single-domain antibodies (sdAbs) derived from human VH are considered to be less soluble and prone to aggregate which makes it difficult to determine the crystal structures. In this study, we isolated and characterized two anti-human epidermal growth factor receptor-2 (HER2) sdAbs, Gr3 and Gr6,...

    Simultaneous excitation of cavity resonance (CR) and surface plasmon resonance (SPR) was observed in the angular spectrum by substituting Ag/Al2O3/Ag layers for the metal film in a Kretschmann structure. Two reflective valleys, elicited respectively by CR and SPR, appeared at different positions...

    Coherent phonon spectroscopy of a high-quality InN epitaxial layer is carried out using time-resolved second-harmonic generation. A coherent longitudinal optical phonon and plasmon coupling mode only at 447 cm-1 can be resolved in the spectrum. Its frequency shows no dependence on the...

    In contrast to earlier classical studies that analyze the surface Bloch modes supported by metallic gratings composed of slits as collective surface-plasmon-polaritons (SPPs) resonances (or poles) of the entire periodic problem, we study the normalized rate of SPPs that are locally launched on...
