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

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Sarah Zayouna; [2020]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Linköpings universitet/Informationskodning

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

    Abstract : 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. READ MORE

  6. 5. Optical forces from dielectric slot waveguides on dielectric nanoparticles

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Anton Möller; [2018]
