These applications require state-of-the-art engineering to reach optimized functionalities such as high directivity and radiation efficiency, low sidelobe levels, broadband and tunable capabilities, and compact design. In this work, we report on the numerical optimization of the directivity of optical traveling wave antennas made from low-loss dielectric materials using full-wave numerical simulations in conjunction with the particle swarm optimization algorithm. The antennas are composed of a reflector and a director deposited on a glass substrate, and an emitter placed in the feed gap between them serves as an internal source of excitation. In particular, we analyze antennas with rectangular- and horn-shaped directors made of either hafnium dioxide or silicon. The optimized antennas produce highly directional emissions due to the presence of two dominant guided TE modes in the director in addition to leaky modes. These guided modes dominate the far-field emission pattern and govern the direction of the main lobe emission, which predominately originates from the end facet of the director. Our work also provides a comprehensive analysis of the modes, radiation patterns, parametric influences, and bandwidths of the antennas, which highlights their robust nature.","lang":"eng"}],"date_created":"2021-12-08T07:14:39Z","file":[{"file_size":14029741,"date_updated":"2021-12-08T08:26:57Z","embargo":"2022-12-08","relation":"main_file","content_type":"application/pdf","file_id":"28417","creator":"fossie","access_level":"local","file_name":"2021-12 Farheen - JOSA B - Optimization of optical nanoantennas.pdf","embargo_to":"open_access","date_created":"2021-12-08T08:26:57Z"},{"file_id":"28418","content_type":"application/pdf","file_name":"2021-12 Farheen - JOSA B - Optimization of optical nanoantennas SUPPLEMENTARY MATERIAL.pdf","access_level":"open_access","file_size":655495,"relation":"supplementary_material","date_updated":"2021-12-08T08:29:49Z","date_created":"2021-12-08T08:29:49Z","creator":"fossie"}],"department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"keyword":["tet_topic_opticalantenna"],"type":"journal_article","author":[{"id":"53444","full_name":"Farheen, Henna","orcid":"0000-0001-7730-3489","last_name":"Farheen","first_name":"Henna"},{"last_name":"Leuteritz","first_name":"Till","full_name":"Leuteritz, Till"},{"full_name":"Linden, Stefan","first_name":"Stefan","last_name":"Linden"},{"id":"46371","full_name":"Myroshnychenko, Viktor","last_name":"Myroshnychenko","first_name":"Viktor"},{"id":"158","full_name":"Förstner, Jens","orcid":"0000-0001-7059-9862","first_name":"Jens","last_name":"Förstner"}],"publication_identifier":{"issn":["0740-3224","1520-8540"]},"year":"2022","title":"Optimization of optical waveguide antennas for directive emission of light","intvolume":"        39","date_updated":"2024-07-22T07:45:12Z","publication_status":"published","language":[{"iso":"eng"}],"doi":"10.1364/josab.438514","citation":{"mla":"Farheen, Henna, et al. “Optimization of Optical Waveguide Antennas for Directive Emission of Light.” <i>Journal of the Optical Society of America B</i>, vol. 39, no. 1, 2022, p. 83, doi:<a href=\"https://doi.org/10.1364/josab.438514\">10.1364/josab.438514</a>.","ama":"Farheen H, Leuteritz T, Linden S, Myroshnychenko V, Förstner J.

In this paper, we design and optimize three distinct broadband traveling-wave tantalum pentoxide antennas exhibiting highly directional characteristics. Our antennas contain a director and reflector deposited on a glass substrate, which are excited by a dipole emitter placed in the feed gap between the two elements. Full-wave simulations in conjunction with global optimization provide structures with an enhanced linear directivity as high as 119 radiating in the substrate. The high directivity is a result of the interplay between two dominant TE modes and the leaky modes present in the antenna director. Furthermore, these low-loss dielectric antennas exhibit a near-unity radiation efficiency at the operational wavelength of 780 nm and maintain a broad bandwidth. Our numerical results are in good agreement with experimental measurements from the optimized antennas fabricated using a two-step electron-beam lithography, revealing the highly directive nature of our structures. We envision that our antenna designs can be conveniently adapted to other dielectric materials and prove instrumental for inter-chip optical communications and other on-chip applications.","lang":"eng"}],"publication":"Optics Express","issue":"11","keyword":["tet_topic_opticalantenna"],"type":"journal_article","department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"date_created":"2022-05-18T16:39:17Z"},{"publication":"Engineering Applications of Artificial Intelligence","department":[{"_id":"52"}],"type":"journal_article","date_created":"2022-11-14T08:13:11Z","intvolume":"       117","publication_status":"published","date_updated":"2023-03-09T10:08:12Z","author":[{"first_name":"Wilhelm","last_name":"Kirchgässner","orcid":"0000-0001-9490-1843","full_name":"Kirchgässner, Wilhelm","id":"49265"},{"first_name":"Oliver","last_name":"Wallscheid","orcid":"https://orcid.org/0000-0001-9362-8777","full_name":"Wallscheid, Oliver","id":"11291"},{"id":"66","full_name":"Böcker, Joachim","orcid":"0000-0002-8480-7295","first_name":"Joachim","last_name":"Böcker"}],"publication_identifier":{"issn":["0952-1976"]},"year":"2022","title":"Thermal neural networks: Lumped-parameter thermal modeling with state-space machine learning","doi":"10.1016/j.engappai.2022.105537","language":[{"iso":"eng"}],"article_number":"105537","project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"citation":{"chicago":"Kirchgässner, Wilhelm, Oliver Wallscheid, and Joachim Böcker. “Thermal Neural Networks: Lumped-Parameter Thermal Modeling with State-Space Machine Learning.” <i>Engineering Applications of Artificial Intelligence</i> 117 (2022). <a href=\"https://doi.org/10.1016/j.engappai.2022.105537\">https://doi.org/10.1016/j.engappai.2022.105537</a>.","short":"W.

Cavities with low <jats:italic>Q</jats:italic>-factors are generally given less attention due to their high losses that quickly destroy quantum systems. However, bad cavities can be utilized for several applications, where lower <jats:italic>Q</jats:italic>-factors are required, e.g., to increase the spectral width of the cavity mode. In this work, we demonstrate that low-<jats:italic>Q</jats:italic> cavities can be beneficial for preparing specific electronic steady states when certain quantum states of light are applied. We investigate the interaction between quantum light with various statistics and matter represented by a Λ-type three-level system in lossy cavities, assuming that cavity losses are the dominant loss mechanism. We show that cavity losses lead to non-trivial electronic steady states that can be controlled by the loss rate and the initial statistics of the quantum fields. We discuss the mechanism of the formation of such steady states on the basis of the equations of motion and present both analytical expressions and numerical simulations for such steady states.</jats:p>"}],"language":[{"iso":"eng"}],"article_number":"063020","doi":"10.1088/1367-2630/ac74d8","author":[{"full_name":"Rose, Hendrik","orcid":"0000-0002-3079-5428","last_name":"Rose","first_name":"Hendrik","id":"55958"},{"full_name":"Tikhonova, O V","last_name":"Tikhonova","first_name":"O V"},{"last_name":"Meier","first_name":"Torsten","orcid":"0000-0001-8864-2072","full_name":"Meier, Torsten","id":"344"},{"full_name":"Sharapova, Polina","first_name":"Polina","last_name":"Sharapova","id":"60286"}],"publication_identifier":{"issn":["1367-2630"]},"title":"Steady states of Λ-type three-level systems excited by quantum light with various photon statistics in lossy cavities","year":"2022","intvolume":"        24","publication_status":"published","date_updated":"2023-04-20T14:51:09Z","citation":{"ama":"Rose H, Tikhonova OV, Meier T, Sharapova P.

Several different approaches to realize solid-state quantum emitters with high performance have been pursued and different concepts for energy tuning have been established. However, the properties of the emitted photons are always defined by the individual quantum emitter and can therefore not be controlled with full flexibility. Here we introduce an all-optical nonlinear method to tailor and control the single photon emission. We demonstrate a laser-controlled down-conversion process from an excited state of a semiconductor quantum three-level system. Based on this concept, we realize energy tuning and polarization control of the single photon emission with a control-laser field. Our results mark an important step towards tailored single photon emission from a photonic quantum system based on quantum optical principles.</jats:p>"}],"date_created":"2023-01-27T13:41:42Z","type":"journal_article","keyword":["General Physics and Astronomy","General Biochemistry","Genetics and Molecular Biology","General Chemistry","Multidisciplinary"],"department":[{"_id":"15"},{"_id":"297"},{"_id":"230"},{"_id":"429"},{"_id":"27"},{"_id":"623"},{"_id":"170"},{"_id":"35"}],"year":"2022","title":"Nonlinear down-conversion in a single quantum dot","publication_identifier":{"issn":["2041-1723"]},"author":[{"full_name":"Jonas, B.","last_name":"Jonas","first_name":"B."},{"id":"10904","last_name":"Heinze","first_name":"Dirk Florian","full_name":"Heinze, Dirk Florian"},{"full_name":"Schöll, E.","last_name":"Schöll","first_name":"E."},{"last_name":"Kallert","first_name":"P.","full_name":"Kallert, P."},{"full_name":"Langer, T.","first_name":"T.","last_name":"Langer"},{"last_name":"Krehs","first_name":"S.","full_name":"Krehs, S."},{"first_name":"A.","last_name":"Widhalm","full_name":"Widhalm, A."},{"last_name":"Jöns","first_name":"Klaus","full_name":"Jöns, Klaus","id":"85353"},{"full_name":"Reuter, Dirk","first_name":"Dirk","last_name":"Reuter","id":"37763"},{"full_name":"Schumacher, Stefan","first_name":"Stefan","last_name":"Schumacher","orcid":"0000-0003-4042-4951","id":"27271"},{"id":"606","last_name":"Zrenner","orcid":"0000-0002-5190-0944","first_name":"Artur","full_name":"Zrenner, Artur"}],"publication_status":"published","date_updated":"2023-04-20T15:18:31Z","intvolume":"        13","article_number":"1387","language":[{"iso":"eng"}],"doi":"10.1038/s41467-022-28993-3","citation":{"mla":"Jonas, B., et al. “Nonlinear Down-Conversion in a Single Quantum Dot.” <i>Nature Communications</i>, vol. 13, no. 1, 1387, Springer Science and Business Media LLC, 2022, doi:<a href=\"https://doi.org/10.1038/s41467-022-28993-3\">10.1038/s41467-022-28993-3</a>.","ama":"Jonas B, Heinze DF, Schöll E, et al.

In this work, the formation of (defect) bound polarons in lithium niobate is studied by ab initio molecular dynamics. The calculations show a broad scatter of polaron formation times. Rising temperature increases the share of trajectories with long formation times, which leads to an overall increase of the average formation time with temperature. However, even at elevated temperatures, the average formation time does not exceed the value of 100 femtoseconds, i.e., a value close to the time measured for free, i.e., self-trapped polarons. Analyzing individual trajectories, it is found that the time required for the structural relaxation of the polarons depends sensitively on the excitation of the lithium niobate high-frequency phonon modes and their phase relation.</jats:p>"}],"publication":"Applied Physics A","keyword":["General Materials Science","General Chemistry"],"type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"230"},{"_id":"429"},{"_id":"35"},{"_id":"790"}],"date_created":"2023-01-20T11:18:44Z"},{"project":[{"_id":"53","name":"TRR 142: TRR 142"},{"name":"TRR 142 - B: TRR 142 - Project Area B","_id":"55"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"name":"TRR 142 - B07: TRR 142 - Subproject B07","_id":"168"},{"name":"TRR 142 - A: TRR 142 - Project Area A","_id":"54"},{"name":"TRR 142 - A11: TRR 142 - Subproject A11","_id":"166"}],"citation":{"mla":"Padberg, Laura, et al. “DC Ionic Conductivity in KTP and Its Isomorphs: Properties, Methods for Suppression, and Its Connection to Gray Tracking.” <i>Crystals</i>, vol. 12, 2022, p. 1359, doi:<a href=\"https://doi.org/10.3390/cryst12101359\">10.3390/cryst12101359</a>.","ama":"Padberg L, Quiring V, Bocchini A, et al.

Furthermore, we create so-called gray tracking in KTP and investigate the ionic conductivity in theses areas. A local unintended reduction of the ionic conductivity is observed in the gray-tracked regions, which also induce additional optical absorption in the material. We show that a thermal treatment in an oxygen-rich atmosphere removes the gray tracking and brings the ionic conductivity as well as the optical transmission back to the original level.
