The theoretical approach provides a self-consistent solution of the dynamics of the electromagnetic field and the material excitations. Due to the influence of the structured dielectric environment on the Coulomb interaction, the exciton resonances and the quasiequilibrium carrier densities in the spatially homogeneous semiconductor become space dependent. It is demonstrated that these inhomogeneities lead to distinct modifications of the optical absorption and gain spectra. As an application, numerically calculated density-dependent optical spectra are analyzed for an array of semiconductor quantum wires which are close to a two-dimensional photonic crystal. The spatial inhomogeneities result in novel excitonic absorption features and modification of the optical gain in these structures.}}, author = {{Reichelt, Matthias and Pasenow, B. and Meier, Torsten and Stroucken, T. and Koch, S.

In the experiments, the diffracted second harmonic generated by sequences of ultrashort laser pulses is detected as a function of the time delay between the pulses. It is demonstrated that this five-wave-mixing technique can be used to measure the temporal evolution of the optical polarization and the photoexcited populations at the surface. The experimental results can be reproduced by numerical solutions of optical Bloch equations. The theoretical analysis allows one to investigate which dephasing times and relaxation processes are compatible with experiment. Furthermore, it is outlined how one can describe optical nonlinearities at surfaces using a microscopic theory within the framework of semiconductor Bloch equations.}}, author = {{Meier, Torsten and Reichelt, Matthias and Koch, S W and Höfer, U}}, issn = {{0953-8984}}, journal = {{Journal of Physics: Condensed Matter}}, number = {{8}}, pages = {{S221--S244}}, title = {{{Femtosecond time-resolved five-wave mixing at silicon surfaces}}}, doi = {{10.1088/0953-8984/17/8/003}}, volume = {{17}}, year = {{2005}}, } @article{1746, author = {{Christ, A. and Zentgraf, Thomas and Kuhl, J. and Tikhodeev, S.
