  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. 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

  4. 3. Distributed Temperature Sensing Using Phase-Sensitive Optical Time Domain Reflectometry

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Simon Ek; [2020]
    Nyckelord :Applied physics; Distributed optical fiber sensing; Rayleigh scattering; OTDR; phase-OTDR; Temperature; Refractive index; Strain; Correlation; RISE; Single mode fiber; SMF; Tillämpad fysik; Distribuerad optisk fibermätning; Rayleigh-spridning; OTDR; phase-OTDR; Temperatur; Brytningsindex; Töjning; RISE; Korrelation; Singelmodfiber; SMF;

    Sammanfattning : This thesis explores and evaluates the temperature measuring capabilities of a phase-sensitive optical time-domain reflectometer (φ-OTDR), which exploits Rayleigh backscattering in normal single mode optical fibers. The device is constructed and its setup explained, and a protocol for making temperature measurements with it is developed. LÄS MER

  5. 4. Single Photon Imaging System for the ESS Linac

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

    Författare :Maria Hoflund; [2019]
    Nyckelord :Imaging; European Spallation Source; Single Photon Detection; Beam Diagnostics; Non-invasive Profile Monitor; Fluorescence Profile Monitor; Technology and Engineering;

    Sammanfattning : To control an accelerating proton beam that travels close to the speed of light, a large number of beam diagnostic instruments are needed. One of the instruments that will be used at the accelerator of the European Spallation Source is a Non-invasive Profile Monitor (NPM). LÄS MER
