  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. Localized and extended states in finite-sized mosaic Wannier-Stark lattices

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Emrah Tortumlu; [2023]
    Nyckelord :Applied Physics; Condensed matter physics; quantum technology; quantum nanophotonics; localization; mobility edge; phase transition; Tillämpad Fysik; Kondenserade materiens fysik; kvantteknologi; kvantnanofotonik; lokalisering; fasövergång;

    Sammanfattning : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

  4. 3. Feedback Control in Silicon Photonic MEMS

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Andrea Cataldo; Björn Åkermark; [2023]
    Nyckelord :;

    Sammanfattning : In this report, we study the implementation of a feedback control system to stabilizea MEMS device for applications in programmable photonic circuits. Specifically, the controller wasimplemented on an all-pass ring resonator, as it was the most suitable MEMS device to implementthe control system on. LÄS MER

  5. 4. Photoluminescence Mapping of Erbium Doped Lithium Niobate

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Chuanshi Xie; [2023]
    Nyckelord :Automotive mapping; Erbium emitters; Ion implantation; Lithium niobate on insulator; photoluminescence microscopy; Automatisk kartläggning; Erbium fotonemitterare; Jonimplantation; Litiumniobat på isolator; fotoluminiscensmikroskopi.;

    Sammanfattning : Lithium niobate (LiNbO3) is a human-made crystalline which is widely used in modern photonics due to its useful properties. In recent years, there has been significant progress in the development of lithium niobate on insulator (LNOI) technology, realizing a fully functional photonic integrated circuits, thanks to its capabilities in both electro-optics and second-order optical nonlinearity.

  7. 5. Impact of nanoparticle plasmons on photoluminescense and upconversion processes in ZnO

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik; Uppsala universitet/Fysikalisk kemi

    Författare :Axel Gudmundsson; [2023]
    Nyckelord :Photoluminescence; Upconversion; Plasmons; ZnO;

    Sammanfattning : The increasing prevalence of glass windows in modern buildings has raised the demand for solar control windows that possess climate-appropriate properties. Glass windows made of abundant and low-cost materials which can both decrease the heating energy consumption as well as enhance the light climate indoors would sufficiently meet the goals of economical yet uplifting buildings.
