  2. 1. Photosensitivity, chemical composition gratings and optical fiber based components

    Author : Michael Fokine; KTH; []
    Keywords : optical fibers; fiber bragg gratings; photosensitivity; thermal stability; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The different topics of this thesis include high-temperaturestable fiber Bragg gratings, photosensitivity and fiber basedcomponents. Fiber Bragg gratings (FBG) are wavelength dispersiverefractive index structures manufactured through UV exposure ofoptical fibers. READ MORE

  4. 2. Additive manufacturing of fused silica glass

    Author : Pawel Maniewski; Michael Fokine; Fredrik Laurell; Daniel Milanese; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser cladding; 3d printing; additive manufacturing; glass; fused silica; laser; scattering; silica; Optik och fotonik; Optics and Photonics; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Additive Manufacturing, of both metals and polymers, has seen rapid development in recent years, whereas the progress in glass has been rather slow. Today, glass can be considered the last frontier without a specialized 3D printing method available. READ MORE

  5. 3. Temperature measurements on silicon core fibers during CO2 laser processing

    Author : Korbinian Mühlberger; Michael Fokine; Valerio Pruneri; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

    Abstract : This thesis presents temperature measurements on silicon core optical fibers during CO2 laser processing. Silicon core fibers are a new type of fiber offering a unique platform to combine the optoelectronic properties of silicon and the possibilities of the optical fiber platform. READ MORE

  6. 4. 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
