  1. 1. Thermal Plasmonic Metasurfaces

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

    Abstract : 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. READ MORE

  2. 2. Electrochromic Plasmonic Metasurfaces for Reflective Displays

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

    Abstract : 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. READ MORE

  3. 3. Nanostructured electromagnetic metasurfaces at optical frequencies

    Author : Nils Odebo Länk; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; high-index nanophotonics; colloidal lithography; metasurfaces; geometric resonances; nanostructures; plasmonics;

    Abstract : Electromagnetic metasurfaces are broadly defined as optically thin layersthat are structured on the subwavelength scale. In general, metasurfacesthus consist of nanoparticles, or other kinds of ”meta-atom”, arranged insome pattern where both the individual particle sizes and the inter-particledistances are much smaller than the wavelength.

  4. 4. Optimization of resonant all-dielectric nanoparticles for optical manipulation and light management

    Author : Nils Odebo Länk; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; FDTD; Nanophotonics; Metasurfaces; Optical Forces; All-dielectric; Perfect Absorption; Silicon;

    Abstract : The resonant interaction between light and matter lies at the heart of nanophotonics research. In particular, nanoparticles that possess optical resonances in the visible spectral range have been avidly studied and employed for various technical and biological applications in the last two decades.

  5. 5. WO3 for reflective displays in color

    Author : Marika Gugole; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; reflective displays; electrochromism; plasmonic metasurfaces; structural colors;

    Abstract : Reflective displays, also known as electronic paper, are very attractive due to their low power consumption and great visibility under bright ambient light conditions. However, reflective displays in color are still limited on the market for two main reasons. READ MORE
