This facilitates a dynamic control of light in a compact form factor that enables the synthesis of arbitrary complex wavefronts in the infrared spectrum. We numerically demonstrate a large-scale two-dimensional silicon-based optical phased array (OPA) composed of nanoantennas with circular gratings that are balanced in power and aligned in phase, required for producing elegant radiation patterns in the far-field. For a wavelength of 1.55 μm, we optimize two antennas for the OPA exhibiting an upward radiation efficiency as high as 90%, with almost 6.8% of optical power concentrated in the field of view. Additionally, we believe that the proposed OPAs can be easily fabricated and would have the ability to generate complex holographic images, rendering them an attractive candidate for a wide range of applications like LiDAR sensors, optical trapping, optogenetic stimulation, and augmented-reality displays."}],"publication":"Photonics and Nanostructures - Fundamentals and Applications","department":[{"_id":"61"},{"_id":"230"},{"_id":"429"},{"_id":"58"}],"keyword":["tet_topic_opticalantenna"],"type":"journal_article","date_created":"2023-12-21T09:30:03Z","file":[{"date_created":"2023-12-21T09:34:17Z","creator":"fossie","file_id":"50013","content_type":"application/pdf","relation":"main_file","date_updated":"2023-12-21T09:34:17Z","file_name":"2ß23-12 Farheen - PNFA - Optimized, highly efficient silicon antennas for optical phased arrays.pdf","file_size":3339442,"access_level":"open_access"}]},{"title":"How to suppress radiative losses in high-contrast integrated Bragg gratings","year":"2023","publication_identifier":{"issn":["0740-3224","1520-8540"]},"author":[{"full_name":"Hammer, Manfred","last_name":"Hammer","orcid":"0000-0002-6331-9348","first_name":"Manfred","id":"48077"},{"last_name":"Farheen","orcid":"0000-0001-7730-3489","first_name":"Henna","full_name":"Farheen, Henna","id":"53444"},{"id":"158","orcid":"0000-0001-7059-9862","last_name":"Förstner","first_name":"Jens","full_name":"Förstner, Jens"}],"publication_status":"published","date_updated":"2024-07-22T07:44:38Z","intvolume":"        40","language":[{"iso":"eng"}],"doi":"10.1364/josab.485725","issue":"4","publication":"Journal of the Optical Society of America B","abstract":[{"text":"High-contrast slab waveguide Bragg gratings with 1D periodicity are investigated.

We consider a series of symmetric, fully and partly etched finite gratings, for parameters found in integrated silicon photonics. These can act as spectral filters with a reasonably flattop response. Apodization can lead to more box shaped reflectance and transmittance spectra.

We show that this enhancement originates from a new type of multi-mode Fano mechanism. These ‘Super-Fano’ resonances are investigated numerically in great detail using full-wave simulations. The theoretically predicted behavior of the metasurface is experimentally verified by linear and nonlinear transmission spectroscopy. Moreover, quantitative nonlinear measurements are performed, in which an absolute conversion efficiency as high as ηmax ≈ 2.8 × 10−7 a peak power intensity of 1.2 GW cm−2 is found. Compared to an unpatterned silicon film of the same thickness amplification factors of up to ~900 are demonstrated. Our results pave the way to exploiting a strong Fano-type multi-mode coupling in metasurfaces for high THG in potential applications.","lang":"eng"}],"issue":"1","publication":"Light: Science & Applications","department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"keyword":["tet_topic_meta"],"type":"journal_article","date_created":"2023-04-21T09:45:07Z","file":[{"file_id":"44098","content_type":"application/pdf","file_name":"2023-04 Hähnel - LSA - Multimode Fano THG.pdf","file_size":2088874,"access_level":"open_access","relation":"main_file","date_updated":"2023-04-21T10:00:27Z","date_created":"2023-04-21T10:00:27Z","creator":"fossie"},{"creator":"fossie","date_created":"2023-04-21T10:03:30Z","file_name":"2023-04 Hähnel - LSA - Multimode Fano THG (supplementary information).pdf","access_level":"open_access","file_size":986743,"relation":"supplementary_material","date_updated":"2023-04-21T10:03:30Z","file_id":"44099","content_type":"application/pdf"}],"article_type":"original","intvolume":"        12","publication_status":"published","date_updated":"2023-04-21T10:04:05Z","publication_identifier":{"issn":["2047-7538"]},"author":[{"full_name":"Hähnel, David","first_name":"David","last_name":"Hähnel"},{"full_name":"Golla, Christian","last_name":"Golla","first_name":"Christian"},{"full_name":"Albert, Maximilian","first_name":"Maximilian","last_name":"Albert"},{"last_name":"Zentgraf","orcid":"0000-0002-8662-1101","first_name":"Thomas","full_name":"Zentgraf, Thomas","id":"30525"},{"id":"46371","last_name":"Myroshnychenko","first_name":"Viktor","full_name":"Myroshnychenko, Viktor"},{"id":"158","first_name":"Jens","last_name":"Förstner","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens"},{"orcid":"https://orcid.org/0000-0002-3787-3572","last_name":"Meier","first_name":"Cedrik","full_name":"Meier, Cedrik","id":"20798"}],"year":"2023","title":"A multi-mode super-fano mechanism for enhanced third harmonic generation in silicon metasurfaces","doi":"https://doi.org/10.1038/s41377-023-01134-1","language":[{"iso":"eng"}]},{"has_accepted_license":"1","status":"public","user_id":"158","ddc":["530"],"_id":"45596","publisher":"American Chemical Society (ACS)","project":[{"name":"TRR 142 - B06: TRR 142 - Ultraschnelle kohärente opto-elektronische Kontrolle eines photonischen Quantensystems (B06*)","grant_number":"231447078","_id":"167"},{"_id":"55","name":"TRR 142 - B: TRR 142 - Project Area B"},{"grant_number":"231447078","_id":"53","name":"TRR 142: TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"name":"TRR 142 - C05: TRR 142 - Nichtlineare optische Oberflächen basierend auf ZnO-plasmonischen Hybrid-Nanostrukturen (C05)","_id":"75","grant_number":"231447078"},{"_id":"56","name":"TRR 142 - C: TRR 142 - Project Area C"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"file_date_updated":"2023-06-13T09:48:17Z","citation":{"short":"D.

Tailoring phase and amplitude of a nonlinearly generated wave with a high emission efficiency using resonance-based metasurfaces is a challenging task that often requires state-of-the-art numerical methods. Here, we propose a simple yet effective approach combining a sampling method with a Monte Carlo approach to design the third-harmonic wavefront generated by all-dielectric metasurfaces composed of elliptical silicon nanodisks. Using this approach, we theoretically demonstrate the full nonlinear 2π phase control with a uniform and highest possible amplitude in the considered parameter space, allowing us to design metasurfaces operating as third harmonic beam deflectors capable of steering light into a desired direction with high emission efficiency. The TH beam deflection with a record calculated average conversion efficiency of 1.2 × 10–1 W–2 is achieved. We anticipate that the proposed approach will be widely applied as alternative to commonly used optimization algorithms with higher complexity and implementation effort for the design of metasurfaces with other holographic functionalities.","lang":"eng"}],"publication":"ACS Photonics","type":"journal_article","keyword":["tet_topic_meta"],"department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"file":[{"date_created":"2023-06-13T09:48:17Z","creator":"fossie","content_type":"application/pdf","file_id":"45597","date_updated":"2023-06-13T09:48:17Z","relation":"main_file","file_size":5382111,"access_level":"open_access","file_name":"2023-06 Hähnel - ACS Photonics - Efficient Modeling and Tailoring of Nonlinear Wavefronts in Dielectric Metasurfaces.pdf"}],"date_created":"2023-06-13T09:43:25Z"},{"citation":{"ieee":"H.

Wave-mixing experiments are often described with semiclassical models, where the light is modeled classically and the material quantum mechanically. Here, however, we use a fully quantized model, where the light is given by a quantum state of light. Quantum light involves more degrees of freedom than classical light as e.g., its photon statistics and quantum correlations, which is a promising resource for quantum devices, such as quantum memories. The light-matter interaction is treated with a Jaynes-Cummings type model and the quantum field is given by a single mode since the quantum dots are embedded in a microcavity. We present numerical simulations of the four-wave-mixing response of a homogeneous system for pulse sequences and find a significant dependence of the result on the photon statistics of the incident pulses. The model constitutes a problem with a large state space which arises from the frequency distribution of the transition energies of the inhomogeneously broadened quantum dot ensemble that is coupled with a quantum light mode. Here we approximate the dynamics by summing over individual quantum dot-microcavity systems. Photon echoes arising from the excitation with different quantum states of light are simulated and compared."}],"language":[{"iso":"eng"}],"series_title":"SPIE Proceedings","article_number":"124190H","doi":"10.1117/12.2647700","author":[{"id":"55958","full_name":"Rose, Hendrik","last_name":"Rose","orcid":"0000-0002-3079-5428","first_name":"Hendrik"},{"full_name":"Grisard, S.","first_name":"S.","last_name":"Grisard"},{"last_name":"Trifonov","first_name":"A.

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.","lang":"eng"}],"publication":"Integrated Optics: Devices, Materials, and Technologies XXVII"},{"oa":"1","citation":{"ama":"Scharwald D, Meier T, Sharapova P.

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. It reports non‐trivial dependencies on system parameters and use the predictive power of the combined theoretical approach to determine the optimal range of Purcell enhancement that maximizes indistinguishability and entanglement to near unity values, here specifically for the telecom C‐band at 1550 nm.</jats:p>"}],"issue":"1","publication":"Advanced Quantum Technologies","doi":"10.1002/qute.202300142","language":[{"iso":"eng"}],"article_number":"2300142","intvolume":"         7","date_updated":"2025-09-12T11:16:12Z","publication_status":"published","publication_identifier":{"issn":["2511-9044","2511-9044"]},"author":[{"full_name":"Bauch, David","last_name":"Bauch","first_name":"David"},{"full_name":"Siebert, Dustin","last_name":"Siebert","first_name":"Dustin"},{"id":"85353","full_name":"Jöns, Klaus D.","first_name":"Klaus D.","last_name":"Jöns"},{"id":"158","full_name":"Förstner, Jens","orcid":"0000-0001-7059-9862","first_name":"Jens","last_name":"Förstner"},{"id":"27271","last_name":"Schumacher","orcid":"0000-0003-4042-4951","first_name":"Stefan","full_name":"Schumacher, Stefan"}],"year":"2023","title":"On‐Demand Indistinguishable and Entangled Photons Using Tailored Cavity Designs","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen","_id":"53"},{"_id":"55","name":"TRR 142 - Project Area B"},{"_id":"56","name":"TRR 142 - Project Area C"},{"name":"TRR 142; TP B06: Ultraschnelle kohärente opto-elektronische Kontrolle eines photonischen Quantensystems","_id":"167"},{"_id":"173","name":"TRR 142; TP C09: Ideale Erzeugung von Photonenpaaren für Verschränkungsaustausch bei Telekom Wellenlängen"},{"_id":"266","name":"PhoQC: Photonisches Quantencomputing"}],"citation":{"mla":"Bauch, David, et al. “On‐Demand Indistinguishable and Entangled Photons Using Tailored Cavity Designs.” <i>Advanced Quantum Technologies</i>, vol. 7, no. 1, 2300142, Wiley, 2023, doi:<a href=\"https://doi.org/10.1002/qute.202300142\">10.1002/qute.202300142</a>.","bibtex":"@article{Bauch_Siebert_Jöns_Förstner_Schumacher_2023, title={On‐Demand Indistinguishable and Entangled Photons Using Tailored Cavity Designs}, volume={7}, DOI={<a href=\"https://doi.org/10.1002/qute.202300142\">10.1002/qute.202300142</a>}, number={12300142}, journal={Advanced Quantum Technologies}, publisher={Wiley}, author={Bauch, David and Siebert, Dustin and Jöns, Klaus D. and Förstner, Jens and Schumacher, Stefan}, year={2023} }","ama":"Bauch D, Siebert D, Jöns KD, Förstner J, Schumacher S.
