The aim of the project is twofold: We will support the members of the research group by solving numerical and theoretical problems related to experiments on the op-tics of photonic nanowires. Further we will develop new models to analyze the interac-tion and dynamics of evanescently coupled photonic wires in arrays.Our support of the research group will be based on our expertise in optics and in the analysis and modeling of nanooptical systems. This includes numerical simulations of the field structures of guided modes and of the efficiencies of reflectors at the end of the wires. Based on that we will calculate the absorption of individual wires as well as Q and Purcell factors of wire based resonantors. We will include light matter interaction and current dynamics in electrically driven wires into our numerical simulations and will develop a simplified model of the photonic wire laser to understand its dynamics and nonlinear response. In parallel we will investigate the optical response of bundles of coupled nanowires with respect to their ability to absorb light in solar cells. Further investigations will concentrate on the theoretical description of arrays of evanescently coupled nanowire lasers. We will analyze regular arrays in terms of active photonic crystals and will investigate collective effects on the emission characteristics, the Q- and Purcell factors of Bloch modes. Extending the already developed simplified model of the photonic wire laser towards coupled cavities we will investigate nonlinearly induced self organization as the formation of pattern or localized structures and will study effects of disorder and Anderson localization on the dynamics in the laser array.
