2. 1. Microsystems Technology for Underwater Vehicle Applications

   Author : Jonas Jonsson; Greger Thornell; Hugo Nguyen; Johan Köhler; Uppsala universitet; []
   Keywords : Aquatic; Submersible; Underwater; Micro; Miniaturized; Sonar; Sidescan; Topography; Laser; Diffractive; Optics; Sampler; Particle; Microorganism; Acoustic; Enriching; Conductivity; Temperature; Depth; CTD; Flow; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

   Abstract : The aim of this thesis work has been to investigate how miniaturization, such as microsystems technology, can potentially increase the scientific throughput in exploration of hard-to-reach underwater environments, such as the subglacial lakes of Antarctica, or other challenging environments, including cave systems and wrecks. A number of instruments and subsystems applicable to miniature submersibles have been developed and studied, and their potential to provide a high functionality density for size-restricted exploration platforms has been assessed.

5. 3. Optical Detection Using Computer Screen Photo-assisted Techniques and Ellipsometry

   Author : Jimmy W. P. Bakker; Hans Arwin; Jin Gang; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optical sensing; Biohttps: www.diva-portal.org liu webform form.jsp#paper0sensing; Ellipsometry; Computer Screen Photo-assisted Technique; Fluorescence; Immunoassays; Optics; Optik;

   Abstract : Two main subjects, ellipsometry and computer screen photo-assisted techniques (CSPT), form the main line in this thesis. Ellipsometry is an optical technique based on the detection of polarization changes of light upon interaction with a sample. READ MORE

6. 4. Silicon-based Photonic Devices : Design, Fabrication and Characterization

   Author : Ziyang Zhang; Min Qiu; Thomas Koch; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photonic Devices; Silicon Photonics; Parallel Computation; Nanofabrication; Electron Beam Lithography; Optical Characterisation; Optics; Optik;

   Abstract : The field of Information and Communication Technologies is witnessing a development speed unprecedented in history. Moore’s law proves that the processor speed and memory size are roughly doubling each 18 months, which is expected to continue in the next decade. READ MORE

7. 5. Optical Studies of Single Quantum Dots

   Author : Jonas Persson; Fasta tillståndets fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; nano-optics; quantum optics; photoluminescence; micro-photoluminescence; single photon generation; Semiconductory physics; Halvledarfysik; low-dimensional structures; quantum dots; Stranski-Krastanow; Fysicumarkivet A:2004:Persson;

   Abstract : This thesis presents spectroscopic studies of single self-assembled InP quantum dots (QDs). The electronic properties of these QDs have been studied by photoluminescence (PL) and scanning tunnelling luminescence (STL). The QDs were grown in the Stranski-Krastanow mode and were embedded in GaInP. READ MORE
