    A plasmonic waveguide is a promising candidate for nano-optical waveguides. First we review the principles and unique characteristics of plasmonic waveguides and compare them to conventional dielectric waveguides. Then, we demonstrate the propagation of a surface plasmon polariton along a metal slab waveguide. A symmetric metal slab waveguide simultaneously supports two opposite types of a surface plasmon mode similar to a metal film: short-range and long-range type modes. The strong field confinement of the short-range mode plays a crucial role in nano-optical waveguides. To avoid the trade-off between field confinement and propagation length, we demonstrate selective mode excitation and mutual mode conversion for superfocusing mediated by the long-range mode.

  • Plasmonics in Organic Light-Emitting Diodes and Organic Thin-Film Solar Cells

    A large part of the emission energy of electrically generated excitons transfers to the surface plasmons that are propagating at the cathode surface of organic light-emitting diodes (OLEDs), reducing external quantum efficiency. We describe the effect of the introduction of nanostructures into cathode surfaces on the improvement of the light extraction efficiency in OLEDs. Organic thin-film solar cells (OSCs) have similar structures to OLEDs. Thus, considering reciprocity, similar effect owing to the introduction of nanostructures can be expected. Two types of OSCs are described. In one OSC, nanostructure is introduced into the back reflector to improve the conversion efficiency. In the other OSC, a thin silver film with nanoholes replaces the indium tin oxide transparent electrode, which is usually used in OSCs.

  • Switching of Localized Surface Plasmon Resonance Using A Phase-Change Material and Applications to Intelligent Computing

    We investigated the modulation of the localized surface plasmon resonance (LSPR) of a gold nanoparticle (AuNP) using a GeSbTe (GST) film as an active medium. We demonstrate high-contrast switching of LSPR in an AuNP/GST and an AuNP/GST/Au nanosandwich structure upon phase change. To go beyond this single-particle switching functionality, we consider the plasmon particle system interacting with a phase change material (PCM) to discuss the possibility of parallel processing devices with memory functionality, making use of the plasticity and threshold behavior, which is inherently involved in PCMs. We demonstrate that temporal and spatial evolution of a plasmon-PCM array system can be equivalent to a cellular automata algorithm.

    We report the experimental demonstration of fluorescence enhancement in using surface plasmon excitation in deep-ultraviolet (deep-UV) region. Surface plasmon resonance in deep-UV is excited on aluminum thin film in the Kretschmann configuration. We also consider about the oxidization layer on the aluminum and evaluate the thickness of the layer with fitting with calculation results. Surface plasmon resonance was excited light on the film of 18 nm-thick aluminum with 6.5 nm-thick alumina. Fluorescence of CdS quantum dots coated on this aluminum film was enhanced to 18-fold in intensity by the surface plasmon excitation. The application for multi-color imaging of biological cells is also demonstrated.

  • Development of Dual-Probe Scanning Near-Field Optical Microscopy

    Dual-probe scanning near-field optical microscopy (DSNOM) is a useful nanoscopic tool to visualize local carrier motions. We developed a new DSNOM system with a novel distance control technique, which can independently control the sample-probe distance and the probe-probe distance. Thus, we applied it to the assessment of the carrier dynamics in a green-light-emitting InGaN single-quantumwell. It is clearly demonstrated that carriers anisotropically diffuse up to several hundred nanometers along a specific direction toward local potential minima showing a strong-photoluminescence domain because potential peaks cause carriers to travel a roundabout route around them. Moreover, we visualized the propagation of surface plasmon polaritons (SPPs) in a Ag waveguide structure, where twodimensional interference fringes are observed due to the multiple reflections at the side edges of a waveguide showing a wave character of SPPs.

  • Nanoplasmonic Excitations and Carrier Control in Oxide Semiconductors

    Oxide plasmonics have received much attention as new phenomena with potential applications in optical fields as diverse as energy-harvesting and sensing devices. Semiconductor materials (In2O3 and ZnO)are expected for alternative plasmonic nanomaterials in the near- to mid-infrared range. In this work, optical properties of carrier-dependent local surface plasmons (LSPs) were investigated using dopant-controlled In2O3: Sn nanoparticles (NPs). From a systematic correlation between LSP excitations and electron carriers, electron-impurity scattering contributed towards plasmon damping as one of a factor that is absent in metal NPs. A threshold electron density (ne) from a damping dominated regime to a quenched damping regime appeared at around 1020 cm‒3. The validity of Mie theory failed in ITO NPs with high ne greater than 1020 cm‒3 since the role of electron carriers could enhance LSPs with simultaneous damped plasmonic excitations, which is valuable information to realize plasmonic nanomaterials with high performance based on oxide semiconductors.

    A spectral cross-correlation interferometry, which was combined with a near-field scanning optical microscope, and a cross-correlation dark-field imaging microscope were applied in the spatiotemporal characterization of femtosecond plasmon localized at gold nanostructures, surface plasmon polariton propagated at a plasmon waveguide, and plasmon nano-focusing at a tapered gold tip. Based on the plasmon response functions in both the amplitude and phase obtained from these measurements, the femtosecond plasmon pulse was deterministically tailored by shaping the femtosecond excitation laser pulses
