Coupled semiconductor Bloch and Maxwell equations are used to investigate the performance of semiconductor microcavity structures, photonic band gap systems, and lasers. The predictive potential of the microscopic theory is demonstrated for several examples of practical importance. Optical gain and output characteristics are computed for modern vertical external cavity surface emitting laser structures. It is shown how design flexibilities can be used to optimize the device performance. Nanostructures are proposed where semiconductor quantum wells are embedded in one-dimensional photonic crystals. For field modes spectrally below the photonic band edge it is shown that the optical gain and absorption can be enhanced by more than one order of magnitude over the value of the homogeneous medium. The increased gain can be used for laser action by placing quantum wells and a suitably designed photonic crystal structure inside a microcavity.}}, author = {{Thränhardt, A. and Meier, Torsten and Reichelt, Matthias and Schlichenmaier, C. and Pasenow, B. and Kuznetsova, I. and Becker, S. and Stroucken, T. and Hader, J. and Zakharian, A.R. and Moloney, J.V. and Chow, W.W. and Koch, S.W.}}, issn = {{0022-3093}}, journal = {{Journal of Non-Crystalline Solids}}, number = {{23-25}}, pages = {{2480--2483}}, title = {{{Microscopic modeling of the optical properties of semiconductor nanostructures}}}, doi = {{10.1016/j.jnoncrysol.2006.02.064}}, volume = {{352}}, year = {{2006}}, } @article{23492, abstract = {{The coherent ultrafast optical injection and the temporal evolution of charge and spin currents in semiconductors is analyzed using a microscopic many-body theory.
