26. Design and Construction of a Multi-Port Beamsplitter Based on Few-Mode-Fibers
University essay from Linköpings universitet/InformationskodningAbstract : A MBS (Multi-port beamsplitter) for higher dimensional quantum communication has been designed and constructed and the theory and method for this is presented in this thesis. It uses optical fibers in a heterogeneous structure with a single-mode fiber spliced to a multi-mode fiber and then spliced to a few-mode fiber. READ MORE

27. Modeling of optical microresonator frequency combs
University essay from Linköpings universitet/Institutionen för fysik, kemi och biologiAbstract : An optical frequency comb is a structure of equidistant, coherent spectral components which can be thought of as a large array of individual phase-locked laser sources. Their utilization in precision spectroscopy garnering part of the 2005 Nobel prize, optical frequency combs constitute a relatively novel technology with a large number of potential and actual applications.

28. Theoretical and experimental investigation of themagneto-optical eect in graphene in the THz region
University essay from Uppsala universitet/FREIAAbstract : In many optics applications we need lenses with dynamically tunable focal lengths. One design of such a lensis developed in and it relies on the magneto-optical eect. In this design, a graphene layer is placed ina magnetic eld that varies quadratically in space. READ MORE

29. Real-time video Bokeh
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Bokeh is defined as a soft out of focus blur. An image with bokeh has a subject in focus and an artistically blurry background. To capture images with real bokeh, specific camera parameter choices need to be made. One essential choice is to use a big lens with a wide aperture. READ MORE

30. Generating fishing boats behaviour based on historic AIS data : A method to generate maritime trajectories based on historicpositional data
University essay from Linköpings universitet/Artificiell intelligens och integrerade datorsystemAbstract : This thesis describes a method to generate new trajectories based on historic positiondata for a given geographical area. The thesis uses AIS-data from fishing boats to first describe a method that uses DBSCAN and OPTICS algorithms to cluster the data into clustersbased on routes where the boats travel and areas where the boats fish.
