1. 1. Space-Division-Multiplexing Platform for a Delayed-Choice Experiment

   University essay from Linköpings universitet/Informationskodning

   Author : Hilma Karlsson; [2023]
   Keywords : Wheeler s delayed choice; wave-particle delayed choice; Sagnac interferometer; Mach-Zehnder interferometer; complementarity relation; spatial modes; space-division-multiplexing; LP-modes; few-mode fibers; quantum communication; quantum optics;

   Abstract : This master’s thesis explores a space-division-multiplexing (SDM) platform fora delayed-choice experiment. SDM is a multiplexing technique for optical datatransmission that employs spatial modes in a multi- or few-mode fiber to increasethe transmission capacity. The spatial modes can thus be used as separate channels. READ MORE

3. 2. Characterization and Stabilization of Transverse Spatial Modes of Light in Few-Mode Optical Fibers

   University essay from Linköpings universitet/Informationskodning

   Author : Oscar Pihl; [2023]
   Keywords : spatial modes; Space division multiplexing; SDM; superpositions; LP-modes; few-mode fibers; quantum communication; quantum optics; adaptive optics; stochastic parallel gradient descent; SPGD; mode control; QKD; polarization controller; paddle controller; QRNG; quantum random number generator; spatial modes; perturbation effects;

   Abstract : With the growing need for secure and high-capacity communications, innovative solutions are needed to meet the demands of tomorrow. One such innovation is to make use of the still unutilized spatial dimension of light in communications, which has promising applications in both enabling higher data traffic as well as the security protocols of the future in quantum communications.

4. 3. Simulation of the Filling of Epoxy in Resin Impregnated Paper Bushings : Analysis of Temperature Measurements during Filling of Epoxy and the Generation of New Filling Recipes to Avoid Cavities in the RIP Bushing

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Hanna Damsgaard Falck; [2023]
   Keywords : Porous media; COMSOL Multiphysicis; Darcy s Law; Richard s Equation; Resin Impregnated Paper Bushings; RIP Bushings; Bushings; Transformers; Epoxy; Simulation;

   Abstract : The goal of the project was to create a model in COMSOL Multiphysics that can simulate thefilling of resin (epoxy) in Resin Impregnated Paper (RIP) bushings. Using the model new fillingrecipes that avoid problematic double-fronts and thereby avoid the creation of cavities in thebushings should be designed. READ MORE

5. 4. Design and Construction of a Multi-Port Beamsplitter Based on Few-Mode-Fibers

   University essay from Linköpings universitet/Informationskodning

   Author : Daniel Spegel-Lexne; [2022]
   Keywords : beamsplitter; spatial modes; Space division multiplexing; superpositions; LP-modes; few-mode fibers; multi-mode interference; self-imaging; heterogeneous fiber structures; quantum communication; quantum optics;

   Abstract : 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

6. 5. Indoor VLC behaviour  with RGB spectral power distribution using simulation.

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Siva Babu Ajjapu; Sasank Reddy Lokireddy; [2021]
   Keywords : ;

   Abstract : n recent years visible light communication (VLC) has been one of the technologies overgrowing in this competitive world and breaking through the wireless transmission of future mobile communications. This VLC replaces radio frequency (RF), which has several important features like large bandwidth, low cost, unlicensed spectrum. READ MORE
