3. Mitigation of nonlinear fiber distortion using phase conjugation
Sammanfattning : This thesis is devoted to the study of fiber-optic communication systems that mitigate nonlinear distortion due to the Kerr effect by transmitting a phase-conjugated copy alongside the signal followed by coherent superposition. This kind of communication systems are referred to as phase-conjugated twin waves systems when the phase-conjugated copy is transmitted on the orthogonal polarization. LÄS MER
4. Nonlinear intrachannel distortion in high-speed optical transmission systems
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
5. Tailored fiber lasers and their use in nonlinear optics
Sammanfattning : 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. LÄS MER
