  2. 21. Silicon Based Photonic Devices and Their Applications

    Author : Qiang Li; Min Qiu; Geert Morthier; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optics; Optik;

    Abstract : The integration of modern electronic devices for information processing is rapidly ap-proaching an interconnect bottleneck. Silicon photonics can be a promising solution forcircumventing this bottleneck, as already being anticipated by many electronics manu-facturers including HP, IBM and Intel. READ MORE

  4. 22. Wavefront Aberrations and Peripheral Vision

    Author : Linda Lundström; Peter Unsbo; Austin Roorda; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optics; Human eye; Aberrations; Peripheral vision; Central visual field loss; Optics; Optik;

    Abstract : Failing eyesight causes a dramatic change in life. The aim of this project is to help people with large central visual field loss to better utilize their remaining vision. Central visual field loss means that the person has to rely on peripheral vision since the direct vision is lost, often due to a dysfunctional macula. READ MORE

  5. 23. Interdomain Traffic Engineering and Faster Restoration in Optical Networks

    Author : Americo Francisco Muchanga; Björn Pehrson; Lena Wosinska; Fredrik Orava; Mouftah Hussein; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interdomain Routing; Network Recovery; Restoration in Optical Networks; Optics; Optik;

    Abstract : Internet traffic has surpassed voice traffic and is dominating in transmission networks. The Internet Protocol (IP) is now being used to encapsulate various kinds of services. The new services have different requirements than the initial type of traffic that was carried by the Internet network and IP. READ MORE

  6. 24. Quantum Optics and Quantum Information Processing in Rare-Earth-Ion-Doped Crystals

    Author : Nicklas Ohlsson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rare-earth ions; Optical processing; Optical storage; Electromagnetism; akustik; optik; Elektromagnetism; optics; acoustics; Photon echo; Quantum optics; Quantum computing; Fysicumarkivet A:2003:Ohlsson;

    Abstract : In this thesis, aspects of the use of cryogenically cooled rare-earth-ion-doped crystals in the fields of quantum optics and quantum information processing are addressed. The experiments and theoretical considerations referred to in this thesis are based on the coherent transient interaction between light and the ions in the crystals. READ MORE
