    Abstract : 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. READ MORE

  5. 3. Hybrid fiber preform fabrication using CO laser heating

    Author : Taras Oriekhov; Michael Fokine; Cruz José; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Preform; CO laser; silicon-core fiber; semiconductor-core fiber; specialty fiber; optical fiber.; Optik och fotonik; Optics and Photonics;

    Abstract : This thesis describes the development of a new prototyping technique for specialty optical fibers and covers all the fabrication steps from preform to fiber. The technique allows to produce fibers of a custom core structure and material composition, mainly focusing on semiconductor core fibers. READ MORE
