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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Azizahalhakim Sudirman; Gunnar Björk; Gilberto Brambilla; [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. VCSEL Techniques for Wavelength-Multiplexed Optical Interconnects

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Mehdi Jahed; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon photonic integration; vertical-cavity surface-emitting laser; transverse and polarization mode filter; optical interconnect; distributed Bragg reflector.; wavelengthmultiplexing;

    Abstract : The majority of global data communication is taking place within data centers where data is stored and processed and where the largest part of the power used for global networking is consumed. With the rapidly increasing use of Internet-based applications and services, data centers are equipped with a larger number of servers and switches requiring higher bandwidth connectivity. READ MORE
