    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

  4. 3. Characterization of Silicon Waveguides For Non-Dispersive Infrared Gas Sensors

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Sarah Zayouna; [2020]
    Nyckelord :;

    Sammanfattning : Carbon dioxide is an important gas for life on Earth. But as human activities have been expanding throughout modern history, the CO2 concentration in the atmosphere is increasing. High concentrations of carbon dioxide can lead to various consequences, such as climate change and poor air quality both indoors and outdoors. LÄS MER

  5. 4. Active Phase Compensation in a Fiber-Optical Mach-Zehnder Interferometer

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Joakim Argillander; [2020]
    Nyckelord :phase stability; interferometer; quantum key distribution; fpga; automatic control; fasstabilitet; interferometer; kvantnyckeldistribution; fpga; reglerteknik;

    Sammanfattning : This thesis investigates the phenomena of phase stability in a fiber-optical MZI (Mach-Zehnder Interferometer). The MZI is a key building block of optical systems for use in experiments with both continuous-wave light and with single photons. LÄS MER

  7. 5. Koppling av ljus in i en bandvågledare av kiselnitrat

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Erik Rydving; Ludvig Doeser; [2019]
    Nyckelord :;

    Sammanfattning : Den senaste teknologiska utvecklingen har gjort det möjligt att miniatyrisera optiska komponenter ner på ett fotoniskt integrerat kretskort. Sammankopplingen mellan olika komponenter möjliggörs av vågledare, i vilka informationsbäraren, en enskild foton, propagerar. LÄS MER
