  1. 1. Electrochromic Plasmonic Metasurfaces for Reflective Displays

    Författare :Kunli Xiong; Chalmers University of Technology; []
    Nyckelord :Plasmonic; Keywords: Colorful electronic paper; Conductive polymer.;

    Sammanfattning : Plasmonic nanomaterials provide brilliant colors that arise from the ambient light coupling to the free electrons in metals. In the Roman empire, noble metal nanoparticles were used for staining glass in Church windows and tableware. LÄS MER

  3. 2. Thermal Plasmonic Metasurfaces

    Författare :Gustav Edman Jönsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Plasmonic materials can form viable optical absorbers that offer new possibilities for device designs as they potentially have large optical cross-sections with readily tuned spectral positions and widths. Applications for such materials include heat generation via optical absorption. LÄS MER

    Sammanfattning : In this thesis, several kinds of artificial plasmonic biosensors are introduced. They havedifferent nanostructures which are nanoholes, nanowells and nanopores. The fabricationtechnologies are introduced. All these nanostructures are fabricated based on colloidallithography technology and following by several special steps. LÄS MER

  5. 4. Plasmonic waveguides and resonators for optical communication applications

    Författare :Yi Song; Min Qiu; Ping Shum; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plasmonic; Photonics; Fotonik;

    Sammanfattning : Photonic circuits can transmit data signals in a much higher speed thanconventional electronic circuits. However, miniaturization of photonic circuitsand devices is hindered by the existence of light diffraction limit. A promisingsolution to this problem is by exploiting plasmonic systems for guiding andmanipulating signals at optical frequencies. LÄS MER

  7. 5. Photothermal Effect in Plasmonic Nanostructures and its Applications

    Författare :Xi Chen; Min Qiu; Sergey I. Bozhevolnyi; KTH; []
