1. Modeling and Compensation of Polarization Effects in Fiber-Optic Communication Systems
Abstract : Optical communication systems that exploit the orthogonality between two polarizations of light convey information over optical fibers by modulating data over the two polarizations. In an idealized scenario, the two polarizations propagate through the fiber without interfering. READ MORE

2. Media Echo Chambers: Selective Exposure and Confirmation Bias in Media Use, and its Consequences for Political Polarization
Abstract : The new digital media landscape has created a high-choice media environment that has made it easier for people to find news and information that support their political beliefs and attitudes, and avoid news and information that challenge those beliefs or attitudes. How does this affect people’s selection of content and political polarization in the long run? This thesis investigates the relationship between different political preferences (political party, political interest and ideological leaning) and selective media use over time among the Swedish population, and whether this selectivity leads to political polarization (ideological polarization and affective polarization).

4. Light propagation in an anisotropically scattering medium
Abstract : Scattering is the main phenomenon of light-matter interaction. In this thesis, we consider one specific case of light propagation in a material whose structure causes anisotropic optical scattering - transparent wood. READ MORE

5. Photospheric emission from structured, relativistic jets : applications to gamma-ray burst spectra and polarization
Abstract : The radiative mechanism responsible for the prompt gamma-ray burst (GRB) emission remains elusive. For the last decade, optically thin synchrotron emission from shocks internal to the GRB jet appeared to be the most plausible explanation. READ MORE
