  7. 5. Increased Functionality of Optical Fibers for Life-Science Applications

    Författare :Azizahalhakim Sudirman; Gunnar Björk; Gilberto Brambilla; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiberoptics; microstructured fiber; fiber - based optofluidics; laser ablation; microfluidics; reflectometry; fluorescence detection; fiber - based spectroscopy; Fysik; Physics;

    Sammanfattning : 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. LÄS MER
