21. Broadband Photon Time-of-Flight Spectroscopy on Pharmaceutical Tablets and Dairy Products
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/AtomfysikAbstract : In this thesis, Photon Time-of-Flight Spectroscopy (PTOFS) is presented as a method to measure absorption and scattering spectra of turbid media samples in the near infra red wavelength range. In particular, absorption and scattering spectra measured on pharmaceutical tablets and dairy products are used to analyse the composition of the samples. READ MORE

22. Optical and Magneto-Optical Measurements of Plasmonic Magnetic Nanostructures
University essay from Uppsala universitet/MaterialfysikAbstract : At the interface between a metal and dielectric, it is possible for an electromagnetic wave to couple with the conduction electrons of the metal to create a coupled oscillation known as a surface plasmon. These surface plasmons can exhibit properties which are not shared with their purely electronic or electromagnetic components. READ MORE

23. Growth and Characterization of Polycrystalline Indium Phosphide on Silicon
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : III-V thin film solar cells attract large interest among the scientific community as a highly efficient solar energy source. High cost of the III-V materials, however, is the fundamental limitation for using these materials as a household energy source. READ MORE

24. Planar Plasmonic Devices for Controlling Polarization of Light
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : Planar nanostructures made of noble metal can efficiently control transmission of light, thanks to surface plasmon polaritons (SPPs) mediated through interaction between such a structure and incoming light. In this thesis, we numerically characterize, with a 3D finiteelement method, three types of plasmonic devices: plasmonic radial/azimuthal filter, plasmonic quarter-wave plate made of a periodic array of round holes in a thin metallic film, and a plasmonic quarter-wave plate with a periodic array of cross-shaped apertures.

25. Plasmonic Waveguides : Design and Comparative Study
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : Although photonics offers an attractive solution to the speed limitation of electronics, reducing the size of bulky photonic components is one of the major issues towards the implementation of photonic integrated circuits. Plasmonic circuits, which tightly confine electromagnetic waves at the metal-dielectric interface, can be a potential solution to this problem. READ MORE
