The near band-gap semiconductor response is determined by the optical interaction with the resonant or near resonant material polarization that may result in the excitation of carriers (electron–hole pairs) and/or transient coherent nonlinearities. The microscopic analysis of these effects requires the investigation of the relevant quasi-particles and their interactions. Whereas the basic occurrence of a blue shift can be motivated already based on a simple two-level model, a more detailed understanding of the optical Stark effect in semiconductors requires a microscopic modeling of the relevant bands as well as the inclusion of the many-body Coulomb interaction. Compensations among the first- and higher-order Coulomb terms at the spectral positions of the exciton are obtained in the differential absorption induced by incoherent occupations."}],"_id":"43303","publisher":"Elsevier","page":"231-313","volume":67,"editor":[{"first_name":"K.T.","last_name":"Tsen","full_name":"Tsen, K.T."}],"user_id":"49063","status":"public","citation":{"apa":"Meier, T., &#38; Koch, S.

For negative delay times and collinearly polarized excitation a pronounced exciton–biexciton beating at the exciton resonance is observed that is vanishing for long negative delays owing to the faster dephasing in the two-exciton continuum compared with the bound biexciton state.

This was attributed to higher-order Coulomb correlations, interpretable as bound and unbound two-exciton states and memory effects. For co-circularly polarized pulses the well-known blue shift was found. Here we present a related effect occurring in the higher-intensity regime.

When a quantum-well exciton transition is resonant with a single mode of a high-Q microcavity the linear reponse of the coupled system may be described in terms of normal modes (\"cavity polaritons\"), which arise as a result of the interplay of absorption and dispersion of the exciton transition within the cavity. The nonlinear response of these systems has often been discussed in terms of \"polaritonic nonlinearities\". It is desirable to investigate the nonlinearities of normal-mode microcavities (NMC's) at the same level and to determine if the microscopic theory accounting for the bare-QW response also quantitatively accounts for the normal-mode nonlinear response. We report here an extensive series of pump-probe experiments, investigating the time-resolved reflectivity of an NMC as a function of pump and probe polarization and pump fluence.","lang":"eng"}],"extern":"1","publication":"Quantum Electronics and Laser Science Conference","doi":"10.1109/QELS.2001.962141","language":[{"iso":"eng"}],"date_updated":"2023-04-24T07:50:36Z","publication_status":"published","title":"Coherent optical nonlinearities in normal mode microcavities","year":"2001","author":[{"id":"344","last_name":"Meier","first_name":"Torsten","orcid":"0000-0001-8864-2072","full_name":"Meier, Torsten"},{"full_name":"Lee, Y-.S","first_name":"Y-.S","last_name":"Lee"},{"first_name":"T.B.","last_name":"Norris","full_name":"Norris, T.B."},{"last_name":"Khitrova","first_name":"G.","full_name":"Khitrova, G."},{"full_name":"Gibbs, H.M.","last_name":"Gibbs","first_name":"H.M."},{"full_name":"Sieh, C.","first_name":"C.","last_name":"Sieh"},{"last_name":"Koch","first_name":"S.W.","full_name":"Koch, S.W."},{"full_name":"Jahnke, F.","last_name":"Jahnke","first_name":"F."}],"publication_identifier":{"isbn":["1-55752-663-X"]}},{"publication":"Quantum Electronics and Laser Science Conference","extern":"1","abstract":[{"lang":"eng","text":"Summary form only given.
