   Sammanfattning : The subject of this thesis is the exploration of new concepts for compact solid-state lasers in the visible and near-infrared spectral range using new components such as volume Bragg gratings for wavelength stabilisation and wavelength tuning. Also single-walled carbon nanotubes for mode-locking and Q-switching of lasers have been studied. LÄS MER

3. 7. Hybrid Plasmonics for Energy Harvesting and Sensing of Radiation and Heat

   Författare :Mina Shiran Chaharsoughi; Magnus Jonsson; Xavier Crispin; Simone Fabiano; Eunkyoung Kim; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The special optical properties of subwavelength metallic structures have opened up for numerous applications in different fields. The interaction of light with metal nanostructures leads to the excitation of collective oscillations of conduction-band electrons, known as plasmons. LÄS MER
