  1. 1. Increased Functionality of Optical Fibers for Life-Science Applications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Azizahalhakim Sudirman; KTH.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fiberoptics; microstructured fiber; fiber - based optofluidics; laser ablation; microfluidics; reflectometry; fluorescence detection; fiber - based spectroscopy; Physics; Fysik;

    Abstract : The objective of this thesis work is to increase the functionality of optical fibers for possible applications in life-sciences. Optical fibers are a promising technology for use in biology and medicine. They are low-costwaveguides, flexible and have a small cross-section. They can guide high-power light with low loss in a micrometer core-size. READ MORE

  2. 2. Surface Force and Friction effects of adsorbed layers and surface topography

    Abstract : The main topic of this thesis is realization and characterization of fibre Bragg gratings.A novel versatile grating fabrication technique is developed and a number of gratings are realized, showing the potential of the system. READ MORE

  4. 4. The effect of nano-confinement on hydrogen uptake in metallic superlattices

    University dissertation from Uppsala : Uppsala University

    Author : Sotirios A. Droulias; Uppsala universitet.; [2018]

    Abstract : The absorption of hydrogen is exothermic in vanadium whereas it is endothermic in iron and chromium. Investigations of the hydrogen uptake within Fe/V(001) and Cr/V(001) superlattices allow therefore a detailed exploration of finite size effects and the influence of boundaries on hydrogen absorption.

  5. 5. Theory and Applications of Coupling Based Intensity Modulated Fibre-Optic Sensors

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Johan Jason; Mittuniversitetet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fibre-optics; sensor; intensity modulation; coupling; TECHNOLOGY Electrical engineering; electronics and photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik;

    Abstract : Optical fibre sensors can be used to measure a wide variety of properties. In some cases they have replaced conventional electronic sensors due to their possibility of performing measurements in environments suffering from electromagnetic disturbance, or in harsh environments where electronics cannot survive.
