  1. 1. Nonlinear intrachannel distortion in high-speed optical transmission systems

    Author : Pontus Johannisson; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; all-optical regeneration; nonlinear optics; fiber optics; self-phase modulation; cross-phase modulation; ghost pulses; intrachannel four-wave mixing; timing jitter;

    Abstract : 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. READ MORE

  2. 2. Tailored fiber lasers and their use in nonlinear optics

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Peter Zeil; KTH.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : The objective of this thesis work was to develop tailored fiber lasers, which meet the pump requirement for efficient continuous-wave (cw) frequency conversion to the visible and the mid-infrared wavelength regimes: a stable, high-power, wavelength-tunable, narrow-linewidth output in a single polarization. As a first step, the prospect of tuning ytterbium fiber lasers over an unprecedented wavelength range, from 980nm to 1100nm, was investigated. READ MORE

  3. 3. Microresonator combs for coherent optical communications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Attila Fülöp; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber-optic communication; nonlinear optics; integrated optics devices; four-wave mixing; microresonators;

    Abstract : This thesis covers the study of microresonator-based optical frequency combs for use in coherent optical communication links. Current links typically utilize several free-running lasers to achieve wavelength-division multiplexing (WDM). READ MORE

  4. 4. Optical Memories and Processing in Time- and Frequency Domain

    University dissertation from Department of Physics, Lund University

    Author : Baozhu Luo; Lund University.; Lunds universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optical storage; photon echo; spectral hole burning; nonlinear optics; fiber amplifier; logical operation; phase retrieval; polarization holographic recording and retrieval; optical processing; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1998:Luo;

    Abstract : Spectral hole burning and photon echoes are the techniques for frequency-selective optical memories, which have the potential to increase areal data storage density by a factor 10**7. They also have the capability to perform in-memory data processing. READ MORE

  5. 5. Capacity Analysis and Receiver Design in the Presence of Fiber Nonlinearity

    University dissertation from Department of Physics, Lund University

    Author : Kamran Keykhosravi; []
