  2. 2. Integrated Nonlinear Optics in Silicon Nitride Waveguides

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Clemens Krückel; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integrated optics devices; nonlinear optics materials; four-wave mixing; nonlinear optical signal processing; wavelength conversion devices; nanostructure fabrication;

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

  3. 3. Nonlinear response in engineered optical materials

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Gustav Strömqvist; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; nonlinear index of refraction; double tungstates; periodic poling; KTiOPO4; quasi-phase matching; parametric down-conversion; mirrorless optical parametric oscillators;

    Abstract : Material and structure engineering are increasingly employed in active optical media,in this context defined as media capable of providing laser or/and optical parametric gain. For laser materials, the main aim of the engineering is to tailor the absorption and emission cross sections in order to optimise the laser performance. READ MORE
