1. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. READ MORE

2. Laboratory starlight simulator for future space-based heterodyne interferometry
University essay from Luleå tekniska universitet/RymdteknikAbstract : In astronomy, interferometry by ground-based telescopes offers the greatest angular resolution. However, the Earth´s atmosphere distorts the incident wavefront from a celestial object, leading to blurring and signal loss. It also restricts the transmission of specific wavelengths within the electromagnetic spectrum. READ MORE

3. Simulation of Quantum Cascade Lasers
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysikAbstract : This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. READ MORE

4. Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Aberrations to the wavefront of a laser beam reduce the quality of the focal spot and are generally undesired. This project is aimed at determining the aberrations of laser beams by using a phase retrieval algorithm and to show that it is possible to correct the aberrations with a spatial light modulator to optimize the focal spot.

5. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength
University essay from KTH/Tillämpad fysikAbstract : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. READ MORE
