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 experiments suggest that the heterostructure band offset is type I for x=0.48% and type II for x=2.2%. The situation is more complex for x=0.72% and x=1.25%, since these samples are close to the transition from type I to type II.

The theoretical approach provides a self-consistent solution of the dynamics of the electromagnetic field and the material excitations.

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."}],"extern":"1","publication":"Physical Review B","issue":"3","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"}],"date_created":"2021-08-24T09:19:26Z","status":"public","user_id":"49063","volume":71,"_id":"23496","citation":{"ieee":"M.

One aim of this chapter is to show that microscopic theories, which have been developed for bare semiconductor heterostructures, are also able to describe semiconductor microcavities very well. Therefore, there is no need to phenomenologically introduce polariton-polariton interactions and parametric scattering of cavity polaritons to describe microcavity experiments, but instead a fully microscopic theory based on a Fermionic electron-hole Hamiltonian can be used.\r\n\r\nThe treatment of many-body correlations using the second-order Born approximation and the dynamics-controlled truncation scheme are introduced and analyzed for bare heterostructures. These approaches are able to successfully explain a number of important experimental results which originate from the dynamics of many-body correlations.\r\n\r\nThen measurements of the nonlinear optical properties of a quantum-well microcavity are described. In these experiments the spectrally- and temporally-resolved nonlinear optical response is studied in detail using a pump-probe geometry. In particular, the polarization and intensity dependencies of the spectral probe reflection changes and their temporal evolution are analyzed. The prominent features of these experiments are well accounted for by the microscopic many-body theory."}],"publication":"Optical Microcavities","type":"book_chapter","department":[{"_id":"293"}],"date_created":"2023-04-01T23:16:33Z","publication_status":"published","date_updated":"2023-04-01T23:16:35Z","title":"Nonlinear optical properties of semiconductor quantum wells inside microcavities","year":"2004","author":[{"id":"344","orcid":"0000-0001-8864-2072","first_name":"Torsten","last_name":"Meier","full_name":"Meier, Torsten"},{"full_name":"Sieh, C.","first_name":"C.","last_name":"Sieh"},{"full_name":"Koch, S.W.","first_name":"S.W.","last_name":"Koch"},{"full_name":"Lee, Y.-S","last_name":"Lee","first_name":"Y.-S"},{"last_name":"Norris","first_name":"T.B.","full_name":"Norris, T.B."},{"full_name":"Jahnke, F.","last_name":"Jahnke","first_name":"F."},{"full_name":"Khitrova, G.","last_name":"Khitrova","first_name":"G."},{"full_name":"Gibbs , H.M.","first_name":"H.M.","last_name":"Gibbs "}],"doi":"10.1142/9789812565730_0006","main_file_link":[{"url":"https://www.worldscientific.com/doi/abs/10.1142/9789812565730_0006"}],"language":[{"iso":"eng"}]},{"author":[{"first_name":"Torsten","orcid":"0000-0001-8864-2072","last_name":"Meier","full_name":"Meier, Torsten","id":"344"},{"first_name":"H.","last_name":"Giessen","full_name":"Giessen, H."},{"last_name":"Linden","first_name":"S.","full_name":"Linden, S."},{"first_name":"A.","last_name":"Christ","full_name":"Christ, A."},{"full_name":"Kuhl, J.","first_name":"J.","last_name":"Kuhl"},{"full_name":"Nau, D.","last_name":"Nau","first_name":"D."},{"full_name":"Thomas, P.","first_name":"P.","last_name":"Thomas"},{"last_name":"Koch","first_name":"S.W.","full_name":"Koch, S.W."}],"publication_identifier":{"isbn":["1-55752-770-9"]},"year":"2004","title":"Fano resonances in metallic photonic crystals","date_updated":"2023-04-24T06:26:43Z","publication_status":"published","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://opg.optica.org/abstract.cfm?uri=IQEC-2004-IFC5"}],"article_number":"IFC5","doi":"10.1364/IQEC.2004.IFC5","publication":"Fano resonances in metallic photonic crystals","abstract":[{"text":"We demonstrate that interference of optical excitations of regularly arranged metallic nanodots on a waveguide shows spectral signatures of Fano resonances.

Depending on the time ordering of the pulses, this technique is capable of monitoring the temporal evolution of photoexcited one- or two-photon coherences, or populations. For a particular pulse sequence, the experiments show a delayed rise and a decay of the diffracted signal intensity on time scales of 50 and 250 fs, respectively. This response can be described by optical Bloch equations by including rapid scattering of the photoexcited carriers in the D(down)band of Si(001).","lang":"eng"}],"extern":"1","publication":"Physical Review Letters","issue":"12","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"}],"date_created":"2021-08-24T09:44:59Z","date_updated":"2023-04-24T06:31:23Z","publication_status":"published","intvolume":"        92","year":"2004","title":"Five-Wave-Mixing Spectroscopy of Ultrafast Electron Dynamics at a Si(001) Surface","author":[{"last_name":"Voelkmann","first_name":"C.","full_name":"Voelkmann, C."},{"full_name":"Reichelt, Matthias","last_name":"Reichelt","first_name":"Matthias","id":"138"},{"last_name":"Meier","first_name":"Torsten","orcid":"0000-0001-8864-2072","full_name":"Meier, Torsten","id":"344"},{"last_name":"Koch","first_name":"S.
