    Sammanfattning : Quantum physics allows us a vision of Nature's forces that bind the world, all its seeds and sources. After decades of primarily scientific research, we've arrived at a stage in time where quantum technology can be applied to practical problems and add value outside the field. LÄS MER

  4. 3. Integrated Nonlinear Optics in Silicon Nitride Waveguides

    Författare :Clemens Krückel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integrated optics devices; nonlinear optics materials; four-wave mixing; nonlinear optical signal processing; wavelength conversion devices; nanostructure fabrication;

    Sammanfattning : Current nanofabrication techniques allow patterning of optical waveguides with submicron cores. This results in strong confinement of light, which leads to high optical intensities. LÄS MER

  5. 4. Micro-Optical Elements in Gallium Arsenide and Diamond: Fabrication and Applications

  7. 5. Thermal Plasmonic Metasurfaces

    Författare :Gustav Edman Jönsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; 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
