In the present work we focus on the generation of pairs of photons with high degrees of polarization entanglement and simultaneously high indistinguishibility. We achieve this goal by selectively reducing the biexciton lifetime with an optical resonator. We demonstrate that a suitably tailored circular Bragg reflector fulfills the requirements of sufficient selective Purcell enhancement of biexciton emission paired with spectrally broad photon extraction and two-fold degenerate optical modes. Our in-depth theoretical study combines (i) the optimization of realistic photonic structures solving Maxwell's equations from which model parameters are extracted as input for (ii) microscopic simulations of quantum-dot cavity excitation dynamics with full access to photon properties. We report non-trivial dependencies on system parameters and use the predictive power of our combined theoretical approach to determine the optimal range of Purcell enhancement that maximizes indistinguishability and entanglement to near unity values in the telecom C-band at $1550\\,\\mathrm{nm}$.","lang":"eng"}],"project":[{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"173","grant_number":"231447078","name":"TRR 142 - C09: TRR 142 - Subproject C09"},{"name":"TRR 142 - B06: TRR 142 - Subproject B06","_id":"167","grant_number":"231447078"},{"name":"TRR 142: TRR 142","_id":"53","grant_number":"231447078"},{"name":"TRR 142 - B: TRR 142 - Project Area B","_id":"55"},{"name":"TRR 142 - C: TRR 142 - Project Area C","_id":"56"}],"citation":{"ieee":"D.

Here, an orientation dependent polarization conversion effect is reported for light reflected from diamond‐structure‐based photonic crystals (D‐structure) inside the scales of a beetle, the weevil Entimus imperialis. When linearly polarized light propagates along its 〈100〉 directions, the D‐structure behaves analogous to a half‐wave plate in reflection but based on a different mechanism. The D‐structure rotates the polarization direction of linearly polarized light, and reflects circularly polarized light of both handednesses without changing it. This polarization effect is different from circular dichroism occurring in chiral biological photonic structures discovered before. The structural origin of this effect is symmetry breaking inside D‐structure's unit cell. This finding demonstrates that natural photonic structures can exploit multiple functionalities inherent to the design principles of their structural organization. Aiming at transferring the inherent polarization effect of the biological D‐structure to technically realizable materials, three simplified biomimetic structural models are derived and it is theoretically demonstrated that they retain the effect. Out of these structures, functioning woodpile structure prototypes are fabricated.","lang":"eng"}],"file":[{"date_created":"2018-10-24T11:55:33Z","creator":"fossie","success":1,"content_type":"application/pdf","file_id":"4832","date_updated":"2018-10-24T11:55:33Z","relation":"main_file","file_size":4191754,"access_level":"closed","file_name":"2018-10 Xia Wu - Advanced Optical Materials - Polarization Conversion Effect in Biological and Synthetic Photonic Diamond Structures.pdf"}],"date_created":"2018-10-24T11:50:29Z","keyword":["tet_topic_phc","tet_topic_bio"],"type":"journal_article","department":[{"_id":"61"}]},{"date_updated":"2022-01-06T06:51:58Z","publication_status":"published","intvolume":"         5","title":"Tailored UV Emission by Nonlinear IR Excitation from ZnO Photonic Crystal Nanocavities","year":"2018","author":[{"full_name":"Hoffmann, Sandro P.","last_name":"Hoffmann","first_name":"Sandro P."},{"last_name":"Albert","first_name":"Maximilian","full_name":"Albert, Maximilian"},{"full_name":"Weber, Nils","last_name":"Weber","first_name":"Nils"},{"last_name":"Sievers","first_name":"Denis","full_name":"Sievers, Denis"},{"id":"158","last_name":"Förstner","orcid":"0000-0001-7059-9862","first_name":"Jens","full_name":"Förstner, Jens"},{"full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","first_name":"Thomas","last_name":"Zentgraf","id":"30525"},{"full_name":"Meier, Cedrik","last_name":"Meier","first_name":"Cedrik","orcid":"https://orcid.org/0000-0002-3787-3572","id":"20798"}],"publication_identifier":{"issn":["2330-4022","2330-4022"]},"doi":"10.1021/acsphotonics.7b01228","language":[{"iso":"eng"}],"publication":"ACS Photonics","type":"journal_article","keyword":["tet_topic_phc"],"department":[{"_id":"15"},{"_id":"230"},{"_id":"61"},{"_id":"287"},{"_id":"35"},{"_id":"289"}],"file":[{"date_created":"2018-08-16T07:49:44Z","creator":"fossie","file_id":"3915","content_type":"application/pdf","file_name":"2018-03 Hoffmann ACS Photonics - Tailored UV Emission by nonlinear IR excitation from ZnO photonic crystal nanocavities.pdf","access_level":"open_access","file_size":2935858,"relation":"main_file","date_updated":"2018-08-21T10:38:31Z"}],"date_created":"2018-03-20T07:39:36Z","has_accepted_license":"1","status":"public","ddc":["530"],"user_id":"30525","volume":5,"page":"1933-1942","_id":"1430","publisher":"American Chemical Society (ACS)","urn":"14308","project":[{"_id":"53","name":"TRR 142"},{"name":"TRR 142 - Project Area A","_id":"54"},{"_id":"55","name":"TRR 142 - Project Area B"},{"_id":"62","name":"TRR 142 - Subproject A5"},{"name":"TRR 142 - Subproject B1","_id":"66"}],"file_date_updated":"2018-08-21T10:38:31Z","citation":{"apa":"Hoffmann, S.

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 samples were grown by plasma assisted molecular beam epitaxy (MBE). To realize the photonic crystal (PhC) membrane we have chosen a triangular array of holes. The array was fabricated by electron beam lithography and several steps of reactive ion etching (RIE) with the help of a hard mask and an undercut of the active layer. The r/a- ratio of 0.35 was deter- mined by numerical simulations to obtain a preferably wide photonic band gap. Micro-photoluminescence (μ-PL) measurements of the photonic crystals, in particular of a H1 and a L3 cavity, and the emission of the QD ensemble were performed to characterize the samples. The PhCs show high quality factors of 4400 for the H1 cavity and about 5000/3000 for two different modes of the L3 cavity, respectively. The energy of the fundamental modes is in good agreement to the numerical simulations.

The mutual coupling of N resonant quantum dots to a single cavity mode results in a N−−√\r\n scaling of the splitting, known from quantum optics, but corrected by the field amplitude fraction for not collocated quantum dots.","lang":"eng"}],"date_created":"2018-08-22T10:10:39Z","department":[{"_id":"15"},{"_id":"293"}],"type":"conference","keyword":["tet_topic_phc","tet_topic_qd"],"conference":{"location":"Bad Honnef","name":"THE FOURTH INTERNATIONAL WORKSHOP 2011 (AIP Conference Proceedings)"},"status":"public","publisher":"AIP","_id":"4043","page":"123-125","volume":1398,"user_id":"49063","citation":{"mla":"Declair, S., et al. “Simulation of Mutual Coupling of Photonic Crystal Cavity Modes and Semiconductor Quantum Dots.” <i>THE FOURTH INTERNATIONAL WORKSHOP 2011</i>, vol. 1398, no. 123, AIP, 2011, pp. 123–25, doi:<a href=\"https://doi.org/10.1063/1.3644232\">10.1063/1.3644232</a>.","bibtex":"@inproceedings{Declair_Song_Meier_Förstner_2011, series={AIP Conference Proceedings}, title={Simulation of Mutual Coupling of Photonic Crystal Cavity Modes and Semiconductor Quantum Dots}, volume={1398}, DOI={<a href=\"https://doi.org/10.1063/1.3644232\">10.1063/1.3644232</a>}, number={123}, booktitle={THE FOURTH INTERNATIONAL WORKSHOP 2011}, publisher={AIP}, author={Declair, S. and Song, X. and Meier, Torsten and Förstner, Jens}, year={2011}, pages={123–125}, collection={AIP Conference Proceedings} }","ama":"Declair S, Song X, Meier T, Förstner J.

Diese mikroskopische Beschreibung\r\nwird durch Kombination eines allgemeinen Dichtematrixansatzes mit speziellen Methoden\r\nzur Auswertung der Maxwellgleichungen wie der zeitaufgelösten Finite-Differenzen-Methode\r\n(FDTD) erreicht. Die Theorie wird auf verschiedene physikalische Situationen angewendet, wie z.B.\r\nLichtausbreitung in Volumenhalbleitern, Interband- und Intersubbandübergänge in Quantenfilmstrukturen\r\nund optische Anregung von Quantenpunkten. Der Fokus liegt dabei auf der Beschreibung der\r\nlinearen und nichtlinearen Antwort des Vielteilchensystems und seiner Ankopplung an das elektromagnetische\r\nFeld. In diesem Zusammenhang wird sowohl die Erzeugung als auch der Zerfall von optischen\r\nAnregungen untersucht, indem verschiedene Kopplungsmechanismen wie Elektron-Phonon-,\r\nElektron-Photon- und Elektron-Elektron-Wechselwirkung berücksichtigt werden.\r\nIm Bereich der linearen Optik, also für Anregung mit geringer Intensität, ermöglicht die Theorie\r\ndie Berechnung von Absorptionsspektren. Verschiedene Effekte in linearer Optik werden in dieser\r\nArbeit untersucht und beschrieben: Linienaufspaltung durch Polaritonen im Volumenmaterial, Zunahme\r\nder Linienbreite bei Intersubbandübergängen verursacht durch Elektron-Elektron- und Elektron-\r\nPhonon-Streuung in einzelnen Quantenfilmen, Bildung einer optischen Bandlücke durch starke radiative\r\nKopplung in Vielfilmstrukturen in Bragg-Geometrie, Phononenseitenbänder verursacht durch\r\nquantenkinetische Effekte in einzelnen Quantenpunkten und schliesslich Superradianz und Interferenzeffekte\r\nin Quantenpunktgittern.\r\nBei nichtlinearer Anregung treten Dichte-Rabiflops als fundamentale Prozesse in allen betrachteten\r\nSystemen auf und können als kohärente Be- und Entvölkerung von quantenmechanischen Zuständen\r\nbeobachtet werden. Der Einfluss von starker Lichtkopplung und verschiedenen Wechselwirkungen\r\nauf dynamische Größen wie die Besetzung wird untersucht. Bei nichtlinearer Propagation, bei\r\nder sich ein starker Lichtpuls über längere Strecken in einem System bewegt, wird selbstinduzierte\r\nVerstärkung der Transmission näher betrachtet. Des weiteren werden von der Coulombwechselwirkung\r\nverursachte nichtlineare Effekte wie exzitoninduziertes Dephasieren in Volumenmaterial und\r\nverschränkte Zustände in Quantenpunkten untersucht, die einen Zusammenbruch der Hartree-Fock-\r\nNäherung darstellen.\r\nZusammenfassend werden in dieser Arbeit verschiedene lineare und nichtlineare optische Effekte\r\nin Halbleiternanostrukturen verschiedener Dimensionalität mit Hilfe einer allgemeinen Theorie, die\r\neinen Dichtematrixansatz mit den Maxwellschen Gleichungen kombiniert, untersucht."}],"doi":"10.14279/depositonce-999","language":[{"iso":"eng"}],"date_updated":"2022-01-06T07:00:54Z","year":"2004","title":"Light Propagation and Many-Particle Effects in Semiconductor Nanostructures","author":[{"id":"158","last_name":"Förstner","first_name":"Jens","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens"}]}]
