1. Theoretical studies of microcavities and photonic crystals for lasing and waveguiding applications
Abstract : This Licentiate presents the main results of theoretical study of light propagation in photonic structures, namely lasing disk microcavities and photonic crystals. In the first two papers (Paper I and Paper II) we present the developed novel scattering matrix technique dedicated to calculation of resonant states in 2D disk microcavities with the imperfect surface or/and inhomogeneous refractive index.

2. Optical Studies and Applications of Single Quantum Dots
Abstract : The luminescence from single quantum dots has been studied. Single dot photoluminescence was studied under continuous as well as under pulsed excitation. Time-resolved studies revealed fast relaxations in quantum dots. The time resolved measurements were fitted with a set of rate equations. READ MORE

3. Theoretical studies of light propagation in photonic and plasmonic devices
Abstract : Photonics nowadays is one of the most rapidly developing areas of modern physics. Photonic chips are considered to be promising candidates for a new generation of high-performance systems for informational technology, as the photonic devices provide much higher information capacity in comparison to conventional electronics.

4. Towards Single-Ion Detection and Single-Photon Storage in Rare-Earth-Ion-Doped Crystals
Abstract : Solid materials doped with rare-earth ions are considered an attractive platform for quantum information applications. One of the main reasons for this is the exceptionally long optical and hyperfine coherence times of the 4fn states, due to the shielding provided by the outer lying 5s and 5p electrons. READ MORE

5. Strong Light-Matter Coupling: the Road from Conventional to Cavity-Free Polaritons
Abstract : The interaction between light and matter is fundamental in perceiving and understanding the world. The interaction is typically weak, meaning light only perturbs matter without changing its properties. READ MORE
