  1. 1. Parametric interactions with signals and the vacuum

    Författare :Michael Roger Andre Simoen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vacuum; circuit-QED; interferometer; SQUID; dynamical Casimir effect; multimode resonator; pumpistor; mode conversion; superconducting circuits; parametric amplification;

    Sammanfattning : In this thesis I present different experiments on superconducting circuits exploring parametric interactions with external signals and the vacuum in the microwave regime. These parametric processes are the result of the periodic modulation of a property of a system which results in different interactions. LÄS MER

  4. 3. Calibration Procedure and Industrial Applications of Coherence Scanning Interferometer

    Författare :Olena Flys; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coherence Scanning Interferometer; Power Spectral Density; 3D parameters; Characterization; uncertainty;

    Sammanfattning : Countless industrial applications over the past decades have indicated the increased need to relate surface texture to surface function. Measurement and characterization of the areal nature of the surface allows the manufacturer to alter how the surface interacts with surroundings. LÄS MER

  5. 4. Multi frequency interferometer studies of active and starburst galaxies

    Författare :Evert Olsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; galaxies: active; galaxies: ISM; galaxies: starburst; galaxies: evolution;

    Sammanfattning : We report the results of a multi-frequency study of three interactinggalaxies: NGC 5218, NGC 1614 and NGC 4194 (the Medusa merger). These sourcesbelong to different classes of active and starburst galaxies. LÄS MER

  7. 5. Applications of monolithic fiber interferometers and actively controlled fibers

    Författare :Patrik Rugeland; Fredrik Laurell; Walter Margulis; Miguel Andrés; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber; fiber Bragg grating; micro-structured fiber; add drop multiplexer; fiber interferometer; microwave photonics; temperature sensor;

    Sammanfattning : The objective of this thesis was to develop applications of monolithic fiber devices and actively controlled fibers. A special twin-core fiber known as a ‘Gemini’ fiber was used to construct equal arm-length fiber interferometers, impervious to temperature and mechanical perturbations. LÄS MER
