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

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Hilma Karlsson; [2023]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Oscar Pihl; [2023]
    Nyckelord :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;

    Sammanfattning : 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. Effects of Design Space Discretization on Constraint Based Design Space Exploration

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Ludwig Karlsson; [2023]
    Nyckelord :Constraint programming; Design space exploration; Discretization; Multiresolutional analysis; Villkorsprogrammering; Designrymdsutforskning; Diskretisering; Multiupplösningsanalys;

    Sammanfattning : Design Space Exploration (DSE) is the exploration of a space of possible designs with the goal of finding some optimal design according to some constraints and criteria. Within embedded systems design, automated DSE in particular can allow the system designer to efficiently find good solutions in highly complex design spaces. LÄS MER

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

    Master-uppsats, Linköpings universitet/Informationskodning

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

    Sammanfattning : 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. LÄS MER

  7. 5. Importance Sampling in Wireless Communication Systems with Ultra-Low Error Rates

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Bharat Maheshwari; Yewen Zhou; [2022]
    Nyckelord :error region; Monte Carlo; importance sampling; rejection sampling; Kullback-Leibler divergence.; Technology and Engineering;

    Sammanfattning : Simulation mimics the behaviour of real world processes or the system over time. It helps us to understand the impact of modification and the effect of introducing various interventions to a system. LÄS MER
