1. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength
University essay from KTH/Tillämpad fysikAbstract : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. READ MORE

2. Transient Plasma Photonic Crystals - A Route Towards Slow Ultra-intense Light?
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Periodic electron and ion density modulations in near critical density plasmas induced by counterpropagating femtosecond pulses of intensities on the order of 10¹⁵ to 10¹⁶ Wcm⁻² are described in a linear and stationary regime and investigated using particle-in-cell simulations in one and two dimensions. The periodic gratings produce transient plasma photonic crystals lasting up to several picoseconds with ultra-wide angle-selective band gaps on the order of Δω/ω₀ ≈ 10-20%. READ MORE

3. Self-Assembly and Electrical Conductivity of Colloids
University essay from Uppsala universitet/MaterialfysikAbstract : Self-assembly is an astonishing phenomenon at the base of organized structures’ formation from disordered systems. It occurs in nature from atomic and molecular lengths to galactic distances. Nowadays self-assembly of colloidal solutions can be used to fabricate photonic crystals and metamaterials. READ MORE

4. 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

5. Band structure computations for dispersive photonic crystals
University essay from Institutionen för teknik och naturvetenskapAbstract : Photonic crystals are periodic structures that offers the possibility to control the propagation of light. The revised plane wave method has been implemented in order to compute band structures for photonic crystals. The main advantage of the revised plane wave method is that it can handle lossless dispersive materials. READ MORE
