    Abstract : The global traffic is experiencing an exponential growth posing severe challenges to the communication networks in terms of capacity. As a future-proof technology fiber communication is widely implemented in different network segments, which can be categorized by transmission distance as long-haul and short-reach. READ MORE

  4. 2. Si-based structures for light emission and detection

    Author : Amir Karim; Göran Hansson; Wei-Xin Ni; Tom Gregorkiewicz; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : Efforts to improve the optical performance of the indirect bandgap semiconductor silicon (Si) has been a major subject of research in the field of Si photonics due to the promising applications of Si based light emitters and detectors for optical communication. With that motivation three different Si based material systems were investigated; Si:Er/O layered structures, SiGe quantum dots and SiSn nano structures, all grown using the technique of molecular beam epitaxy (MBE).
