  4. 3. Electro-Optical Characterization of Passivated InAsP/InP Quantum Discs-in-Nanowire Heterostructures

    Magister-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Samareh Kordi Jazi; [2018]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Semiconductor nanowires, with their quasi one-dimension geometry, inherently provide strain relaxation for heterogeneous integration and also strong light mode confinement. Nanowire-based photonic devices have also been demonstrated to offer significantly enhanced quantum efficiency, gain and reduced noise. LÄS MER

  5. 4. Interface Roughness in Quantum Cascade Lasers

    Master-uppsats, Lunds universitet/Matematisk fysik

    Författare :Kasparas Antanas Krivas; [2015]
    Nyckelord :Quantum Cascade Lasers; Interface Roughness; Modeling; Physics and Astronomy;

    Sammanfattning : The quantum cascade laser (QCL) is a solid state device capable of generating the coherent mid-infrared and terahertz radiation. It is made from layers of different semiconducting materials. This layered structure gives rise to sub-bands, that are employed to achieve charge inversion necessary for lasing. LÄS MER

  7. 5. Designing an Experiment to Investigate Slow Light Effects in Whispering Gallery Mode Resonators

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Karolina Dorozynska; [2015]
    Nyckelord :Slow light; Whispering Gallery Mode Resonator; WGMR; Atomic physics; Physics and Astronomy;

    Sammanfattning : Slow light and Whispering Gallery Mode Resonators are two interesting and useful fields with applications in optical sensing and laser stabilisation among others. Slow light can lead to long interaction times which are useful in light-matter interactions such as sensitive non-linear optics. LÄS MER
