The experiments have been performed as autocorrelation measurements with ps double pulse laser excitation for resonant and detuned conditions. Measured E-field autocorrelation functions reveal a very strong detuning dependence of the phase shift between laser and cavity field and of the autocorrelation amplitude of the cavity field. The fully resolved phase information allows for a precise frequency discrimination and hence for a precise measurement of the detuning between laser and cavity. The behavior of the autocorrelation amplitude and phase and their detuning dependence can be fully described by an analytic model. Furthermore, coherent control of the cavity field is demonstrated by tailored laser excitation with phase and amplitude controlled pulses. The experimental proof and verification of the above described phenomena became possible by an electric detection scheme, which employs planar photonic crystal microcavity photo diodes with metallic Schottky contacts in the defect region of the resonator. The applied photo current detection was shown to work also efficiently at room temperature, which make electrically contacted microcavities attractive for real world applications."}],"date_created":"2018-08-08T09:35:11Z","file":[{"file_id":"3842","content_type":"application/pdf","relation":"main_file","date_updated":"2018-08-21T10:44:05Z","file_name":"2016-09 Förstner,Reuter,Zrenner_Phase sensitive properties and coherent manipulation of a photonic crystal microcavity.pdf","file_size":3466341,"access_level":"open_access","date_created":"2018-08-08T09:39:54Z","creator":"hclaudia"}],"department":[{"_id":"61"},{"_id":"290"}],"keyword":["tet_topic_phc"],"type":"journal_article"},{"doi":"10.1103/physrevb.94.165310","user_id":"10904","_id":"19210","language":[{"iso":"eng"}],"date_updated":"2022-01-06T06:54:00Z","publication_status":"published","author":[{"full_name":"Breddermann, D.","last_name":"Breddermann","first_name":"D."},{"id":"10904","first_name":"Dirk Florian","last_name":"Heinze","full_name":"Heinze, Dirk Florian"},{"full_name":"Binder, R.","first_name":"R.","last_name":"Binder"},{"last_name":"Zrenner","first_name":"Artur","orcid":"0000-0002-5190-0944","full_name":"Zrenner, Artur","id":"606"},{"first_name":"Stefan","orcid":"0000-0003-4042-4951","last_name":"Schumacher","full_name":"Schumacher, Stefan","id":"27271"}],"publication_identifier":{"issn":["2469-9950","2469-9969"]},"title":"All-optical tailoring of single-photon spectra in a quantum-dot microcavity system","status":"public","year":"2016","type":"journal_article","date_created":"2020-09-09T13:56:53Z","citation":{"chicago":"Breddermann, D., Dirk Florian Heinze, R.

The periodic\r\ndomain inversion was verified by non-invasive confocal second harmonic microscopy. Our\r\nresults show domain patterns in accordance to the electrode mask layout.

Their coupling to the crystal environment manifests itself in a limitation of the spin coherence times to the microsecond range, both for electron and hole spins. This rather short-lived coherence compared to atomic states asks for manipulations on timescales as short as possible. Due to the huge dipole moment for transitions between the valence and conduction band, pulsed laser systems offer the possibility to perform manipulations within picoseconds or even faster. Here, we report on results that show the potential of optical spin manipulations with currently available pulsed laser systems. Using picosecond laser pulses, we demonstrate optically induced spin rotations of electron and hole spins. We further realize the optical decoupling of the hole spins from the nuclear surrounding at the nanosecond timescales and demonstrate an all-optical spin tomography for interacting electron spin sub-ensembles.","lang":"eng"}],"issue":"1","publication":"Applied Physics B"},{"language":[{"iso":"eng"}],"doi":"10.1038/srep10313","title":"Robust Population Inversion by Polarization Selective Pulsed Excitation","year":"2015","publication_identifier":{"issn":["2045-2322"]},"author":[{"first_name":"D.","last_name":"Mantei","full_name":"Mantei, D."},{"id":"158","full_name":"Förstner, Jens","first_name":"Jens","orcid":"0000-0001-7059-9862","last_name":"Förstner"},{"first_name":"S.","last_name":"Gordon","full_name":"Gordon, S."},{"full_name":"Leier, Y.

Usually, the photon is emitted from a single-exciton ground state.\r\nPolarization of the photon and time of emission are either probabilistic or pre-determined by\r\nelectronic properties of the system. Here, we study the direct two-photon emission from the\r\nbiexciton. The two-photon emission is enabled by a laser pulse driving the system into a\r\nvirtual state inside the band gap. From this intermediate state, the single photon of interest\r\nis then spontaneously emitted. We show that emission through this higher-order\r\ntransition provides a versatile approach to generate a single photon. Through the driving\r\nlaser pulse, polarization state, frequency and emission time of the photon can be controlled\r\non-the-fly.","lang":"eng"}],"publication":"Nature Communications","issue":"1","department":[{"_id":"15"},{"_id":"230"},{"_id":"35"},{"_id":"170"},{"_id":"429"}],"type":"journal_article","date_created":"2018-08-30T13:07:30Z","article_type":"original","intvolume":" 6","publication_status":"published","date_updated":"2025-12-05T14:45:38Z","author":[{"last_name":"Heinze","first_name":"Dirk","full_name":"Heinze, Dirk"},{"first_name":"Dominik","last_name":"Breddermann","full_name":"Breddermann, Dominik"},{"full_name":"Zrenner, Artur","last_name":"Zrenner","first_name":"Artur","orcid":"0000-0002-5190-0944","id":"606"},{"last_name":"Schumacher","orcid":"0000-0003-4042-4951","first_name":"Stefan","full_name":"Schumacher, Stefan","id":"27271"}],"publication_identifier":{"issn":["2041-1723"]},"title":"A quantum dot single-photon source with on-the-fly all-optical polarization control and timed emission","year":"2015","doi":"10.1038/ncomms9473","language":[{"iso":"eng"}],"project":[{"_id":"53","name":"TRR 142"},{"name":"TRR 142 - Project Area A","_id":"54"},{"name":"TRR 142 - Subproject A3","_id":"60"},{"name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen","_id":"53"}],"citation":{"bibtex":"@article{Heinze_Breddermann_Zrenner_Schumacher_2015, title={A quantum dot single-photon source with on-the-fly all-optical polarization control and timed emission}, volume={6}, DOI={10.1038/ncomms9473}, number={1}, journal={Nature Communications}, publisher={Springer Nature}, author={Heinze, Dirk and Breddermann, Dominik and Zrenner, Artur and Schumacher, Stefan}, year={2015} }","ama":"Heinze D, Breddermann D, Zrenner A, Schumacher S.
