3. 2. Nonlinear optics in KTiOPO4 for spectral management of ultra-short pulses in the near- and mid-IR

   Författare :Anne-Lise Viotti; Valdas Pasiskevicius; Fredrik Laurell; Paulina Kuo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nonlinear optics; Ferroelectrics; Fysik; Physics;

   Sammanfattning : This thesis explores the possibilities of controlling nonlinear optical interactions in ferroelectric materials for bandwidth tailoring of ultrashort pulses in the pico- and femto-second range. The control is achieved through quasi-phase matching, which is based on alternating the material’s spontaneous polarization into different domains. LÄS MER

4. 3. Prediction of discomfort due to transient whole body vibrations

   Författare :Peter Jönsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

   Sammanfattning : This Licentiate is about Whole Body Vibrations and focuses on transient vibrations with human's discomfort and motion assessment. Whole Body Vibrations occurs when a body is in contact with a vibrating surface. Whole Body Vibrations is a major problem in terrain vehicle, which affects both the physiological and psychological health and discomfort. LÄS MER

5. 4. Microcombs for ultrafast optical interferometry

   Författare :Israel Rebolledo Salgado; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integrated photonics; microcombs; nonlinear optics; supercontinuum generation;

   Sammanfattning : The optical frequency comb has revolutionized the field of laser spectroscopy. This type of laser, characterized by an array of uniformly spaced and coherent laser lines, finds promise in photonic platforms for the integration of chip-scale spectrometers. LÄS MER

7. 5. 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
