1. Distortion and attenuation free gain-assisted Superluminal Propagtion in a Rare-Earth Doped Crystal
Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : A light pulse that travels through a narrow spectral window, i.e. a frequency range of low absorption, within a strongly absorbing frequency range will be delayed due to strong dispersion. LÄS MER
2. Cold amplification and fiber coupling of a super-conducting nanowire single-photon detector
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Single-photon detectors are an essential tool for quantum photonics: one can harness the quantum properties of single photons for quantum communication as well as use the detectors in low illumination applications.Superconducting nanowire single-photon detectors offer high detection efficiency over a widerange of wavelengths, low dark counts, and a good timing resolution compared to single-photonavalanche diodes.

3. Feasibility Study of Resistivity Measurement of Metal Surfaces to Address Potential Dislocations Caused by Surface Conditioning
Master-uppsats, Uppsala universitet/FREIASammanfattning : High electrical fields are needed inside the accelerating cavities of particle accelerators in order to accelerate the particles to higher energies in shorter distances. But high electrical fields will lead to electrical breakdowns. LÄS MER
4. Theoretical and experimental investigation of themagneto-optical eect in graphene in the THz region
L1-uppsats, Uppsala universitet/FREIASammanfattning : In many optics applications we need lenses with dynamically tunable focal lengths. One design of such a lensis developed in and it relies on the magneto-optical eect. In this design, a graphene layer is placed ina magnetic eld that varies quadratically in space. LÄS MER
5. Heat dissipation due to microvibrations in low temperature experiments
Master-uppsats, KTH/FysikSammanfattning : Ultra-sensitive photodetectors on-board space missions need very low temperatures to keep a good resolution. Cryo-coolers, such as pulse-tubes, help maintaining these conditions within a cryostat. In return however, they generate micro-vibrations. LÄS MER
