    Sammanfattning : Increasing the channel bit rate is an efficient way to upgrade traffic capacity in installed transmission links. At bit rates of the order of 40 Gb/s, on-off keying (OOK) transmission becomes severely impaired by non-linear effects especially Intra-channel Four-Wave Mixing (IFWM) which limit the power at which the signal can be transmitted, and ultimately the transmission distance.

    Sammanfattning : The Kerr nonlinearity in optical fibres tends to generate signal distortion in dispersion-managed fibre-optic communication systems. Within a wavelength channel, the resulting intrachannel effects are timing jitter, i.e. LÄS MER

  7. 5. Investigations of Issues Relevant to the Application of Photon Echoes in Information Technology

    Författare :Ulf Elman; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; fibre amplifier; Boolean operation; rare earth metals; Atom- och molekylärfysik; Atomic and molecular physics; optical processing; photon echo; optical storage; Fysicumarkivet A:1998:Elman;

    Sammanfattning : Photon echoes have been studied both experimentally and theoretically, with the main part of the work centred around the concept of using photon echoes for all-optical data storage and processing. The four basic Boolean operators, AND, OR, NOT and XOR have been experimentally demonstrated using photon echoes. LÄS MER
