16. Processing technologies for long-wavelength vertical-cavity lasers
Sammanfattning : Vertical-cavity surface-emitting lasers (VCSELs) areattractive as potential inexpensive high-performance emittersfor fibre-optical communication systems. Their surface-normalemission together with the small dimensions are beneficial forlow-cost fabrication since it allows on-wafer testing,simplified packaging and effective fibre-coupling. LÄS MER
17. Design, Processing, and Characterization of High Frequency Flip Chip Interconnects
Sammanfattning : The demands for high frequency interconnect techniques for microwave integrated circuits (ICs) are growing with increasing operating frequencies of wireless communication systems. Interconnects have significant effect and impact on the overall system performance at high frequencies. LÄS MER
18. Ultraviolet vertical-cavity surface-emitting lasers and vertical microcavities for blue lasers
Sammanfattning : III-nitride materials are used for ultraviolet (UV) and visible light emitters. One such light source is the vertical-cavity surface-emitting laser (VCSEL) that could find applications within areas ranging from sterilization and medical treatment to car headlights and augmented reality displays.

19. Time-resolved x-ray diffraction of nanostructured samples
Sammanfattning : The work presented in this thesis is based on time-resolved x-ray diffraction studies of InSb (111) samples. The experiments were carried out using a pump-probe configuration using short laser pulses as the pump and x-rays as the probe. Laser excitation leads to the formation of a strain pulse that propagates through the sample. LÄS MER
20. Long-Wavelength Vertical-Cavity Lasers : Materials and Device Analysis
Sammanfattning : Vertical-cavity lasers (VCLs) are of great interest as lightsources for fiber-optic communication systems. Such deviceshave a number of advantages over traditional in-plane laserdiodes, including low power consumption, efficient fibercoupling, on-chip testability, as well as potential low-costfabrication and packaging.
