1. Fiber-Optic Systems with Coherent Detection and Four-Dimensional Modulation
Sammanfattning : To increase the data rates of fiber-optic communication systems, modulation formats withhigher spectral efficiency and/or higher power efficiency than binary formats are of greatinterest. These formats require coherent detection and this thesis has been dedicated toinvestigating both novel modulation formats and two different types of coherent systems. LÄS MER
2. Phase-sensitive amplifiers for nonlinearity impairment mitigation in optical fiber transmission links
Sammanfattning : The fundamental limitations in fiber-optic communication are caused by optical amplifier noise and the nonlinear response of the optical fibers. The quantum-limited noise figure of erbium-doped fiber amplifiers (EDFAs) or any phase-insensitive amplifier is 3 dB. LÄS MER
3. 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
4. Nonlinear Propagation of Optical Pulses and Beams
Sammanfattning : The propagation of optical beams and pulses under the influence of nonlinear effects is characterized by a rich variety of phenomena and many potentially important applications. We analyse two main topics in this context: nonlinear beam propagation, and nonlinear pulse propagation in optical fibers. LÄS MER
5. Nonlinear pulse propagation effects for application to optical fibre communication systems
