1. Fano Resonances in Time-Dependent Wells
University essay from Uppsala universitet/MaterialteoriAbstract : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. READ MORE

2. Electro-Optical Characterization of Passivated InAsP/InP Quantum Discs-in-Nanowire Heterostructures
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : Semiconductor nanowires, with their quasi one-dimension geometry, inherently provide strain relaxation for heterogeneous integration and also strong light mode confinement. Nanowire-based photonic devices have also been demonstrated to offer significantly enhanced quantum efficiency, gain and reduced noise. READ MORE

3. Towards a tunable nanometer thick flat lens
University essay from Uppsala universitet/MaterialfysikAbstract : This report examines the cross sections of silver microresonators subjected to an incident light with different polarization. The microresonators had different geometries with and without broken symmetries. READ MORE

4. Absorption of light through isolated and coupled resonances in horizontal InP nanowire arrays
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : We have studied the interaction of light with two types of closely related nanostructures: a single horizontal InP nanowire and an infinite periodic array of such nanowires. The study has been done theoretically by calculating the absorption cross section of the nanowires via a semi analytical method, the Mie theory, and two numerical methods, the scattering matrix method (SMM) and the finite element method (FEM) to perform electromagnetic modeling.

5. Plasmonic resonances in metallic nanoarrays
University essay from Uppsala universitet/MaterialfysikAbstract : The optical and magneto-optical response of plasmonic resonances in metallic nanoarrays out of square structures, either in holes or islands, were investigated. The excitation of the Bragg Plasmons takes place within a grating. READ MORE
