    Sammanfattning : Vertical-cavity lasers (VCLs) are of great interest as lightsources for fiber-optic communication systems. Such deviceshave a number of advantages over traditional in-plane laserdiodes, including low power consumption, efficient fibercoupling, on-chip testability, as well as potential low-costfabrication and packaging.

  5. 4. Cavity enhanced optical sensing

    Författare :Isak Silander; Ove Axner; Aleksandra Foltynowicz; Jong Chow; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical resonators; Fiber Laser; Parametric oscillators; Optical frequency comb; Infrared; Spectroscopy heterodyne; Spectroscopy molecular; Absorption; Dispersion; Lineshapes; Optical standards and testing; Refractivety measurements;

    Sammanfattning : An optical cavity comprises a set of mirrors between which light can be reflected a number of times. The selectivity and stability of optical cavities make them extremely useful as frequency references or discri­mi­nators. LÄS MER

  7. 5. Study of the Superconducting Medium Beta Cavity of the European Spallation Source

    Författare :Saeid Pirani; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SRF elliptical cavity; higher order mode; Qext; field emission; elliptical cavity design; vertical test; Fysicumarkivet A:2020:Pirani;

    Sammanfattning : The thesis explains the design, fabrication, vertical test, higher order mode (HOM) and field emission study of the ESS superconducting medium beta (MB) cavity. The ESS MB cavity is a 6-cell elliptical cavity. The main criteria for a multicell elliptical cavity design are explained. The multicell elliptical cavity fabrication process is discussed. LÄS MER
