  2. 1. Coherent Plasmon-Plasmon and Plasmon-Exciton Interactions at the Nanoscale

    Author : Martin Wersäll; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; directional emission; coherent interactions; strong coupling; localized surface plasmon resonances;

    Abstract : Noble metallic nanoparticles which supports localized surface plasmon resonances, offers a variety of potential scientific as well as industrial applications. Due to a remarkable ability to confine light at nanoscale dimensions, far below the optical diffraction limit, together with an ability to detect minute changes in the local environment plasmonic nanoparticles have paved routes towards several new and intriguing techniques, promising for future applications in areas such as molecular sensing and quantum optics.
