    Sammanfattning : This thesis presents studies on III-V semiconductor waveguides with particular emphasis on second-order optical nonlinearity. The nonlinear processes that were investigated in this thesis are the Second Harmonic Generation (SHG) and the Spontaneous Parametric Down-Conversion (SPDC). LÄS MER

  3. 2. Topological Photonic Lattices

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Zesheng Xu; [2022]
    Nyckelord :Topological photonics; Integrated photonics; Condensed matter physics physics; Optics; Topologisk fotonik; integrerad fotonik; fysik för kondenserad materia; Optik;

    Sammanfattning : Topological Photonics is a rapidly growing field which explores the ideas of topological invariants adapted from condensed matter physics to optical systems. Thanks to integrated photonics platforms, the evolution of light in nanoscale photonic lattices can enable direct measurement of topological properties of the band-structure. LÄS MER

  4. 3. Optical Study of Micro-Resonators with G-centers as an Active Medium

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Baptiste Lefaucher; [2021]
    Nyckelord :G-center; Silicon Photonics; Micro-Resonators Optics; Laser; Photo-Luminescence Spectroscopy; G-center; Kiselfotonik; Mikroresonatoroptik; Laser; Fotoluminescensspektroskopi;

    Sammanfattning : The G-center has recently been identified as the first deterministic single-photon punctual emitter isolated in silicon. This discovery is of great interest for largescale quantum technologies, due to the abilities of silicon in terms of integration and scalability. LÄS MER

  5. 4. Relativistic Visualizations

    Magister-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Andreas Ringstam; [2020]
    Nyckelord :Special relativity; Visualization; see; observe;

    Sammanfattning : Special relativity is an area of physics that is abstract and consists of concepts and effects that is hard to link to everyday experience. From a learning perspective, that is problematic as we form new knowledge by linking it to old experiences. One approach to experience a relativistic environment is through computer simulations.

  7. 5. Design of a compact wavefront sensor for measurements on the human eye

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Charlie Börjeson; [2020]
    Nyckelord :Applied physics; optical physics; visual optics; Tillämpad fysik; optisk fysik; visuell optik;

    Sammanfattning : Wavefront sensors for measurements on human eyes are usually large, expensive and difficult to move. A compact wavefront sensor would be more cost-effective and versatile as is could be used in multiple systems. The aim of this thesis was to produce a more compact and portable wavefront sensor.
