1. 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.

4. Design of a 200Gbps externally modulated laser for opto-electronic integration
University essay from KTH/Tillämpad fysikAbstract : Segmented traveling wave electro-absorption modulators (TWEAMs) can provide a modulation speed above 100 Gb/s, which is needed in new optical communication networks. In the EU-project TWILIGHT, KTH continues the design work of TWEAMs in the EU-projects IPHOBAC and HECTO with the aim to design a new optical modulator to be integrated with an electronic layer.

5. Analysis of Different Switching Patterns to Minimize Losses in a Six- Phase Drive for Marine Application
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Multiphase machines have gained a lot of popularity during the recent years, as they offer certain benefits over their three- phase counterparts. This work investigates the losses of a six- phase drive system for a marine application when supplied by four different switching patterns (also referred to as modulators). READ MORE
