These antennas exhibit highly directive radiation patterns and our studies reveal that this nature comes from two dominant guided TE modes excited in the waveguide-like director of the antenna, in addition to the leaky modes. The optimized antennas possess a broadband nature and have a nearunity radiation efficiency at an operational wavelength of 780 nm. Compared to the previously studied plasmonic antennas for photon emission, our all-dielectric approach demonstrates a new class of highly directional, low-loss, and broadband optical antennas."}],"publication":"Integrated Optics: Devices, Materials, and Technologies XXVII","type":"conference","keyword":["tet_topic_opticalantenna"],"department":[{"_id":"61"},{"_id":"230"},{"_id":"429"},{"_id":"623"}],"file":[{"date_updated":"2023-03-22T09:25:57Z","relation":"main_file","file_size":1426599,"access_level":"local","file_name":"2023-01 Poster Photonics West Henna OWA_A0.pdf","content_type":"application/pdf","file_id":"43062","creator":"fossie","date_created":"2023-03-22T09:25:57Z"}],"date_created":"2023-03-21T12:28:31Z","publication_status":"published","date_updated":"2025-05-23T05:57:14Z","year":"2023","title":"Tailoring the directive nature of optical waveguide antennas","author":[{"full_name":"Farheen, Henna","last_name":"Farheen","orcid":"0000-0001-7730-3489","first_name":"Henna","id":"53444"},{"full_name":"Yan, Lok-Yee","last_name":"Yan","first_name":"Lok-Yee"},{"full_name":"Leuteritz, Till","first_name":"Till","last_name":"Leuteritz"},{"first_name":"Siqi","last_name":"Qiao","full_name":"Qiao, Siqi"},{"first_name":"Florian","last_name":"Spreyer","full_name":"Spreyer, Florian"},{"first_name":"Christian","last_name":"Schlickriede","full_name":"Schlickriede, Christian"},{"full_name":"Quiring, Viktor","last_name":"Quiring","first_name":"Viktor"},{"first_name":"Christof","last_name":"Eigner","full_name":"Eigner, Christof"},{"full_name":"Silberhorn, Christine","last_name":"Silberhorn","first_name":"Christine","id":"26263"},{"first_name":"Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas","id":"30525"},{"last_name":"Linden","first_name":"Stefan","full_name":"Linden, Stefan"},{"full_name":"Myroshnychenko, Viktor","first_name":"Viktor","last_name":"Myroshnychenko","id":"46371"},{"full_name":"Förstner, Jens","orcid":"0000-0001-7059-9862","last_name":"Förstner","first_name":"Jens","id":"158"}],"doi":"10.1117/12.2658921","language":[{"iso":"eng"}]},{"doi":"10.1080/02678292.2023.2171146","language":[{"iso":"eng"}],"date_updated":"2025-05-23T05:52:46Z","intvolume":"        50","year":"2023","title":"Geometric-phase metalens to be used for tunable optical tweezers in microfluidics","author":[{"full_name":"Geromel, René","last_name":"Geromel","first_name":"René"},{"full_name":"Rennerich, Roman","last_name":"Rennerich","first_name":"Roman"},{"full_name":"Zentgraf, Thomas","first_name":"Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","id":"30525"},{"id":"254","first_name":"Heinz-Siegfried","last_name":"Kitzerow","full_name":"Kitzerow, Heinz-Siegfried"}],"type":"journal_article","department":[{"_id":"313"},{"_id":"230"},{"_id":"638"},{"_id":"15"},{"_id":"623"}],"date_created":"2023-01-27T12:42:16Z","abstract":[{"lang":"eng","text":"Geometric-phase dielectric meta-lenses made of silicon with high numerical aperture and short focal lengths are fabricated and characterised.

We combine this equality with results of Guillarmou, Hilgert and Weich (2021) in order to relate the residues to Patterson-Sullivan distributions. Finally we provide proof-of-principle results concerning the numerical calculation of invariant Ruelle distributions for 3-disc scattering systems.","lang":"eng"}],"external_id":{"arxiv":["2112.05791"]},"date_created":"2022-05-04T12:27:46Z","type":"journal_article","department":[{"_id":"10"},{"_id":"548"},{"_id":"623"},{"_id":"15"}],"title":"Meromorphic Continuation of Weighted Zeta Functions on Open Hyperbolic Systems","year":"2023","status":"public","author":[{"id":"50168","first_name":"Philipp","last_name":"Schütte","full_name":"Schütte, Philipp"},{"orcid":"0000-0002-9648-6919","last_name":"Weich","first_name":"Tobias","full_name":"Weich, Tobias","id":"49178"},{"id":"48188","first_name":"Sonja","last_name":"Barkhofen","full_name":"Barkhofen, Sonja"}],"date_updated":"2026-02-18T10:41:07Z","intvolume":"       398","page":"655-678","_id":"31059","language":[{"iso":"eng"}],"user_id":"49178","doi":"https://doi.org/10.1007/s00220-022-04538-z","volume":398},{"year":"2023","title":"On‐Demand Indistinguishable and Entangled Photons Using Tailored Cavity Designs","author":[{"first_name":"David","last_name":"Bauch","full_name":"Bauch, David"},{"last_name":"Siebert","first_name":"Dustin","full_name":"Siebert, Dustin"},{"id":"85353","first_name":"Klaus D.","last_name":"Jöns","full_name":"Jöns, Klaus D."},{"id":"158","first_name":"Jens","orcid":"0000-0001-7059-9862","last_name":"Förstner","full_name":"Förstner, Jens"},{"id":"27271","full_name":"Schumacher, Stefan","first_name":"Stefan","last_name":"Schumacher","orcid":"0000-0003-4042-4951"}],"publication_identifier":{"issn":["2511-9044","2511-9044"]},"date_updated":"2025-09-12T11:16:12Z","publication_status":"published","intvolume":"         7","article_number":"2300142","language":[{"iso":"eng"}],"doi":"10.1002/qute.202300142","issue":"1","publication":"Advanced Quantum Technologies","abstract":[{"text":"<jats:title>Abstract</jats:title><jats:p>The biexciton‐exciton emission cascade commonly used in quantum‐dot systems to generate polarization entanglement yields photons with intrinsically limited indistinguishability. In the present work, it focuses on the generation of pairs of photons with high degrees of polarization entanglement and simultaneously high indistinguishability. It achieves this goal by selectively reducing the biexciton lifetime with an optical resonator. It demonstrates 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 twofold degenerate optical modes. The 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.

To that end, we demonstrate active gating of an SNSPD with a minimum off-to-on rise time of 2.4 ns and a total gate length of 5.0 ns. We show how the rise time depends on the inductance of the detector in combination with the control electronics. The gate window is demonstrated to be fully and freely, electrically tunable up to 500 ns at a repetition rate of 1.0 MHz, as well as ungated, free-running operation. Control electronics to generate the gating are mounted on the 2.3 K stage of a closed-cycle sorption cryostat, while the detector is operated on the cold stage at 0.8 K. We show that the efficiency and timing jitter of the detector is not altered during the on-time of the gating window.

For this reason, a considerable amount of engineering effort has been taken in order to improve the quality of particle sources and system components. At the same time, data analysis and collection methods based on post-selection have been used to mitigate the effect of particle losses. This has allowed for investigating experimentally multi-particle evolutions where the observer lacks knowledge about the system's intermediate propagation states. Nonetheless, the fundamental question how losses affect the behaviour of the surviving subset of a multi-particle system has not been investigated so far. For this reason, here we study the impact of particle losses in a quantum walk of two photons reconstructing the output probability distributions for one photon conditioned on the loss of the other in a known mode and temporal step of our evolution network. We present the underlying theoretical scheme that we have devised in order to model controlled particle losses, we describe an experimental platform capable of implementing our theory in a time multiplexing encoding. In the end we show how localized particle losses change the output distributions without altering their asymptotic spreading properties. Finally we devise a quantum civilization problem, a two walker generalisation of single particle recurrence processes.","lang":"eng"}],"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://iopscience.iop.org/article/10.1088/1402-4896/acbcaa"}],"article_number":"034005","doi":"10.1088/1402-4896/acbcaa","author":[{"full_name":"Pegoraro, Federico","first_name":"Federico","last_name":"Pegoraro","id":"88928"},{"id":"68236","full_name":"Held, Philip","last_name":"Held","first_name":"Philip"},{"full_name":"Barkhofen, Sonja","first_name":"Sonja","last_name":"Barkhofen","id":"48188"},{"first_name":"Benjamin","orcid":"0000-0003-4140-0556 ","last_name":"Brecht","full_name":"Brecht, Benjamin","id":"27150"},{"id":"26263","full_name":"Silberhorn, Christine","first_name":"Christine","last_name":"Silberhorn"}],"publication_identifier":{"issn":["0031-8949","1402-4896"]},"year":"2023","title":"Dynamic conditioning of two particle discrete-time quantum walks","intvolume":"        98","article_type":"original","date_updated":"2026-01-09T09:49:31Z","publication_status":"published","oa":"1","citation":{"chicago":"Pegoraro, Federico, Philip Held, Sonja Barkhofen, Benjamin Brecht, and Christine Silberhorn. “Dynamic Conditioning of Two Particle Discrete-Time Quantum Walks.” <i>Physica Scripta</i> 98, no. 3 (2023). <a href=\"https://doi.org/10.1088/1402-4896/acbcaa\">https://doi.org/10.1088/1402-4896/acbcaa</a>.","short":"F.

By breaking certain spatial symmetries, chiral structures arise and provide robust chiroptical responses to these plasmonic resonances. Here, we observe strong chiroptical responses in the linear and nonlinear optical regime for chiral L-handed helicoid-III nanoparticles and quantify them by means of an asymmetric factor, the so-called g-factor. We calculate the linear optical g-factors for two distinct chiroptical resonances to −0.12 and –0.43 and the nonlinear optical g-factors to −1.45 and −1.63. The results demonstrate that the chirality of the helicoid-III nanoparticles is strongly enhanced in the nonlinear regime."}],"date_created":"2022-03-03T07:18:18Z","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"keyword":["Electrical and Electronic Engineering","Atomic and Molecular Physics","and Optics","Biotechnology","Electronic","Optical and Magnetic Materials"],"type":"journal_article"},{"issue":"12","publication":"Advanced Science","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"keyword":["General Physics and Astronomy","General Engineering","Biochemistry","Genetics and Molecular Biology (miscellaneous)","General Materials Science","General Chemical Engineering","Medicine (miscellaneous)"],"type":"journal_article","date_created":"2022-02-21T08:09:02Z","file":[{"relation":"main_file","date_updated":"2022-03-03T07:23:15Z","file_name":"2022_ACSPhotonics_NonlinearChiral_Arxiv.pdf","access_level":"closed","file_size":1001422,"file_id":"30196","success":1,"content_type":"application/pdf","creator":"zentgraf","date_created":"2022-03-03T07:23:15Z"}],"intvolume":"         9","article_type":"original","date_updated":"2022-04-25T13:04:44Z","publication_status":"published","author":[{"full_name":"Reineke Matsudo, Bernhard","first_name":"Bernhard","last_name":"Reineke Matsudo"},{"full_name":"Sain, Basudeb","last_name":"Sain","first_name":"Basudeb"},{"full_name":"Carletti, Luca","first_name":"Luca","last_name":"Carletti"},{"last_name":"Zhang","first_name":"Xue","full_name":"Zhang, Xue"},{"full_name":"Gao, Wenlong","first_name":"Wenlong","last_name":"Gao"},{"first_name":"Costantino","last_name":"Angelis","full_name":"Angelis, Costantino"},{"full_name":"Huang, Lingling","first_name":"Lingling","last_name":"Huang"},{"id":"30525","first_name":"Thomas","orcid":"0000-0002-8662-1101","last_name":"Zentgraf","full_name":"Zentgraf, Thomas"}],"publication_identifier":{"issn":["2198-3844","2198-3844"]},"title":"Efficient Frequency Conversion with Geometric Phase Control in Optical Metasurfaces","year":"2022","doi":"10.1002/advs.202104508","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://doi.org/10.1002/advs.202104508","open_access":"1"}],"article_number":"2104508","project":[{"_id":"53","name":"TRR 142: TRR 142"},{"name":"TRR 142 - C: TRR 142 - Project Area C","_id":"56"},{"_id":"75","name":"TRR 142 - C5: TRR 142 - Subproject C5"}],"quality_controlled":"1","citation":{"short":"B.

However, pushing the concept of the geometric phase toward the acoustic community still faces challenges. In this work, we utilize two acoustic nonlocal metagratings that could support a direct conversion between an acoustic plane wave and a designated vortex mode to obtain the acoustic geometric phase, in which an orbital angular momentum conversion process plays a vital role. In addition, we realize the acoustic geometric phases of different orders by merely varying the orientation angle of the acoustic nonlocal metagratings. Intriguingly, according to our developed theory, we reveal that the reflective acoustic geometric phase, which is twice the transmissive one, can be readily realized by transferring the transmitted configuration to a reflected one. Both the theoretical study and experimental measurements verify the announced transmissive and reflective acoustic geometric phases. Moreover, the reconfigurability and continuous phase modulation that covers the 2π range shown by the acoustic geometric phases provide us with the alternatives in advanced acoustic wavefront control.","lang":"eng"}],"date_created":"2022-05-27T12:35:53Z","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"keyword":["Physics and Astronomy (miscellaneous)"],"type":"journal_article","status":"public","_id":"31480","publisher":"AIP Publishing","volume":120,"user_id":"30525","citation":{"bibtex":"@article{Liu_Zhou_Wang_Zentgraf_Li_Huang_2022, title={Experimental verification of the acoustic geometric phase}, volume={120}, DOI={<a href=\"https://doi.org/10.1063/5.0091474\">10.1063/5.0091474</a>}, number={21211702}, journal={Applied Physics Letters}, publisher={AIP Publishing}, author={Liu, Bingyi and Zhou, Zhiling and Wang, Yongtian and Zentgraf, Thomas and Li, Yong and Huang, Lingling}, year={2022} }","ama":"Liu B, Zhou Z, Wang Y, Zentgraf T, Li Y, Huang L.
