6. Optical Guiding and Feedback Structures in GaN-Based Vertical-Cavity Surface-Emitting Lasers
Abstract : The Vertical-Cavity Surface-Emitting Laser (VCSEL) made from GaAs-based materials is an established infrared light source, and is produced in large volumes for short-distance optical links, computer mice, and thermal processing systems. A wide range of applications, such as high-resolution printing, general lighting, and biomedical diagnosis and treatment could benefit from using a VCSEL with blue or ultraviolet emission. READ MORE

7. Electrochromism in Metal Oxide Thin Films : Towards long-term durability and materials rejuvenation
Abstract : Electrochromic thin films can effectively regulate the visible and infrared light passing through a window, demonstrating great potential to save energy and offer a comfortable indoor environment in buildings. However, long-term durability is a big issue and the physics behind this is far from clear. READ MORE

8. VCSEL Cavity Engineering for High Speed Modulation and Silicon Photonics Integration
Abstract : The GaAs-based vertical-cavity surface-emitting laser (VCSEL) is the standard light source in today's optical interconnects, due to its energy efficiency, low cost, and high speed already at low drive currents. The latest commercial VCSELs operate at data rates of up to 28 Gb/s, but it is expected that higher speeds will be required in the near future. READ MORE

9. Ultralow noise pre-amplified receiver for free-space optical communications
Abstract : The demand for high data rate in space communication links is increasing due to the growth of space exploration missions inter-satellite, and satellite-to-Earth data transmission. Optical communication systems capable of handling hundreds of Gigabits per second data transmission with a single light carrier and are suitable for such space links. READ MORE

10. InAS Quantum Dots for Laser Applications and Pedogogical, Gender, and Multicultural Aspects in Engineering Education
Abstract : This thesis builds on new cross-disciplinary research between engineering and educational sciences. Recently, two other theses that combine research in physics and education (Åke Ingerman, 2002, and Tom Adawi, 2002) have been completed in Sweden. This thesis consolidates a trend that can benefit both disciplines. READ MORE
