  2. 1. Nonlinear response in engineered optical materials

    Author : Gustav Strömqvist; Valdas Pasiskevicius; Peter Smith; KTH; []
    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

  4. 2. Stability and Mobility of Localized and Extended Excitations in Nonlinear Schrödinger Models

    Author : Michael Öster; Magnus Johansson; Sergej Flach; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-linear dynamics; chaos; Icke-linjär dynamik; kaos;

    Abstract : This thesis is mainly concerned with the properties of some discrete nonlinear Schrödinger equations. These naturally arise in many different physical contexts as the limiting form of general dynamical lattice equations that incorporate nonlinearity and coupling. READ MORE

  5. 3. Nonlinear localization in discrete and continuum systems : applications for optical waveguide arrays

    Author : Michael Öster; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : An introcludion to the formation of coherent structures in spatially discrete and continuous systems is given. Of special interest is the phenomenon of nonlinear localization, where the self-focusing of an excitation is balanced by a dispersive process. READ MORE
