In the field of symbolic projection, research is increasingly focusing on implementing light modulation using energy-efficient, incoherent LEDs rather than lasers. Since light modulation in micro- and nano-optics is typically achieved through phase modulation, Finite-Difference Time-Domain (FDTD) simulations are employed for analysis. The objective of this article is to investigate different approaches for approximating incoherent monochromatic light sources within FDTD simulations. To this end, two approaches based on dipole sources are considered, as well as a method involving plane waves with modulated wavefronts based on Cosine–Fourier functions and a method based on the superposition of Gaussian beams. These methods are evaluated in terms of their accuracy using a two-dimensional double-slit configuration and are compared against a fully incoherent analytical reference."}],"language":[{"iso":"eng"}],"keyword":["tet_topic_opticalantenna","tet_topic_numerics","tet_topic_meta"],"publication_identifier":{"issn":["2304-6732"]},"publication_status":"published","intvolume":" 13","citation":{"bibtex":"@article{Metzner_Potthoff_Zentgraf_Förstner_2026, title={Approximating Incoherent Monochromatic Light Sources in FDTD Simulations}, volume={13}, DOI={10.3390/photonics13020128}, number={2128}, journal={Photonics}, publisher={MDPI AG}, author={Metzner, Dominik and Potthoff, Jens and Zentgraf, Thomas and Förstner, Jens}, year={2026} }","mla":"Metzner, Dominik, et al. “Approximating Incoherent Monochromatic Light Sources in FDTD Simulations.” Photonics, vol. 13, no. 2, 128, MDPI AG, 2026, doi:10.3390/photonics13020128.","short":"D.

So far, investigations involving intimate covalent or ionic bonds have not been a focus. Yet, we show here that an established technique, involving thermocompressional wafer bonding, works well for creating twisted non-van der Waals interfaces. We have successfully bonded z-cut lithium niobate single crystals to create ferroelectric oxide interfaces with strong polar discontinuities and have mapped the associated emergent interfacial conductivity. In some instances, a dramatic change in microstructure occurs, involving local dipolar switching. A twist-induced collapse in the capability of the system to effec8tively screen interfacial bound charge is implied. Importantly, this only occurs around specific moiré twist angles with sparse coincident lattices and associated short-range aperiodicity. In quasicrystals, aperiodicity is known to induce pseudo-bandgaps and we suspect a similar phenomenon here."}],"language":[{"iso":"eng"}],"quality_controlled":"1","issue":"1","year":"2026","publisher":"Springer Science and Business Media LLC","date_created":"2026-03-08T09:20:13Z","title":"Polar discontinuities, emergent conductivity, and critical twist-angle-dependent behaviour at wafer-bonded ferroelectric interfaces","type":"journal_article","status":"public","_id":"64864","user_id":"22501","department":[{"_id":"15"},{"_id":"623"},{"_id":"288"}],"article_type":"original","article_number":"1842","publication_status":"published","publication_identifier":{"issn":["2041-1723"]},"citation":{"apa":"Rogers, A., Holsgrove, K., Schäfer, N.

In this study, a quinuclidine-based catalytic monomer (QMA) was synthesized to create polymer gel dots through the process of photopolymerization that serve as a support for the catalyst. The resulting gel-bound organocatalysts were assembled within a continuous microfluidic reactor to facilitate the Baylis–Hillman reaction between various aldehydes and acrylonitrile at a temperature of 50 °C. The conversion of the product was assessed using 1H NMR spectroscopy as an offline analytical method over a duration of 8 h. The findings indicated that highly reactive aldehydes achieved conversion rates exceeding 90%, in contrast to their less reactive counterparts. Furthermore, these results were juxtaposed with previously published data derived from alternative synthetic methodologies, revealing that the continuous microfluidic reactions employing integrated organocatalysts within polymer networks exhibited significantly higher conversions with reduced reaction times (8 h) at the same temperature (50 °C). Additionally, the influence of different geometries (round, triangular, and square) of the gel dots on catalytic activity was investigated, with round and square gel dots demonstrating slightly superior performance compared with triangular gel dots, attributed to their increased surface area. Moreover, an extended reaction period of 6 days was conducted using 4-bromobenzaldehyde and acrylonitrile, resulting in a conversion rate exceeding 70%, which remained stable for 5 days before experiencing a slight decline due to product accumulation on the gel dots.","lang":"eng"}]},{"article_type":"original","article_number":"e11823","user_id":"30525","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"project":[{"name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen","_id":"53"},{"_id":"54","name":"TRR 142 - Project Area A"},{"name":"TRR 142 - Project Area B","_id":"55"},{"_id":"65","name":"TRR 142; TP A08: Nichtlineare Kopplung von Zwischenschicht-Exzitonen in van der Waals-Heterostrukturen an plasmonische und dielektrische Nanokavitäten"},{"name":"TRR 142; TP B09: Effiziente Erzeugung mit maßgeschneiderter optischer Phaselage der zweiten Harmonischen mittels Quasi-gebundener Zustände in GaAs Metaoberflächen","_id":"170"}],"_id":"61523","status":"public","type":"journal_article","main_file_link":[{"open_access":"1","url":"https://advanced.onlinelibrary.wiley.com/doi/10.1002/adma.202511823"}],"doi":"10.1002/adma.202511823","author":[{"full_name":"Jin, Xiao","last_name":"Jin","first_name":"Xiao"},{"first_name":"Thomas","id":"30525","full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","last_name":"Zentgraf"}],"volume":38,"date_updated":"2026-03-10T08:32:37Z","oa":"1","citation":{"short":"X.

Extensive research has been conducted to enhance the multiplexing capacity for diverse wavefronts. However, the independence of multiplexed channels is fundamentally restricted in techniques using single‐layer metasurfaces, resulting in unavoidable crosstalk and the need for post‐filtering of the output wavefronts. Here, a universal wavefront multiplexing concept is presented based on non‐injective transformation. By employing joint optimization on two metasurfaces, different channels can be independently designed without any constraints on the output wavefronts. To validate this approach, ultra‐compact orbital angular momentum (OAM) sorters are designed. In these experiments, the output beams from different channels can be independently mapped to 2D positions with high fineness. In another application of wavefront‐multiplexed holography, 10‐channel multiplexing is experimentally achieved with minimal crosstalk and without the need for post‐processing. These results demonstrate the independence between channels enabled by the non‐injective transformation in the method. The precise wavefront control and high multiplexing capacity underscore its potential for scalable wavefront manipulation devices."}],"publication":"Advanced Materials","title":"Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation","date_created":"2025-10-06T05:42:21Z","publisher":"Wiley","year":"2026","quality_controlled":"1"},{"language":[{"iso":"ger"}],"_id":"36895","department":[{"_id":"299"}],"user_id":"9605","series_title":"Paderborner Beiträge zur Bildungsforschung und Lehrkräftebildung.","editor":[{"last_name":"Becher","full_name":"Becher, Andrea","first_name":"Andrea"},{"first_name":"Bea","full_name":"Bloh, Bea","last_name":"Bloh"},{"full_name":"Herzig, Bardo","last_name":"Herzig","first_name":"Bardo"},{"first_name":"Pascal","full_name":"Pollmeier, Pascal","last_name":"Pollmeier"}],"status":"public","publication":"Demokratiebildung in der Lehrkräftebildung (Arbeitstitel).

This research introduces a multilayer\r\nsynchronous polarization projection method that fundamentally increases the DoF for polarization\r\nmultiplexing. The DoF equals twice the number of projection layers. We experimentally demonstrate six-\r\nchannel polarization multiplexing holography without position multiplexing. The six-channel multiplexing\r\nresults indicate that our approach exceeds the conventional polarization multiplexing method, yielding an\r\naverage 3.79 dB improvement in extinction ratio across the six channels. Compared with the theoretical\r\nlimit of traditional polarization multiplexing, our method reduces crosstalk by an average of 6.52 dB across\r\nall channels in a seven-channel design.

In this work, we investigate the impact of the optical pulse shape and duration on the accuracy of this method. We find that Gaussian temporal pulse shapes yield cleaner arrival-time histograms and, thus, more accurate PNR, compared to bandpass-filtered pulses of equal bandwidth. For low system jitter and an optical pulse duration comparable to the other jitter contributions, photon numbers can be discriminated in our system with a commercial SNSPD. At 60 ps optical pulse duration, photon-number discrimination is significantly reduced. Furthermore, we highlight the importance of using the correct arrival-time histogram model when analyzing photon-number assignment. Using exponentially modified Gaussian distributions, instead of the commonly used Gaussian distributions, we can more accurately determine photon-number misidentification probabilities.

In most metasurfaces, near-field couplings are treated as being unfavorable perturbations. Here, we experimentally investigate a structure consisting of sinusoidally modulated silicon waveguides where near-field coupling of local resonances leads to negative coupling, i.e., a negative coupling constant. This gives rise to wave-vector-dependent eigenstates of elliptical, linear, and circular polarizations. In particular, fully circular polarization states are not only present at a single point in momentum space (k-space) but also along a line. This circular polarization line, as well as a linear polarization line, emanates from a polarization degeneracy at the Dirac point. We experimentally validate the existence of these eigenstates and demonstrate the energy-, polarization-, and wave vector dependence of this metasurface as well as its sensitivity to fabrication tolerances. By tuning the incident k-vector, certain polarization-energy eigenstates are strongly reflected, allowing for uses in angle-tunable polarization filters and light sources.","lang":"eng"}],"publication":"ACS Photonics","language":[{"iso":"eng"}],"external_id":{"arxiv":["2512.14452"]},"year":"2026","quality_controlled":"1","title":"Polarization- and Wave-Vector Selective Optical Metasurface with Near-Field Coupling","publisher":"American Chemical Society (ACS)","date_created":"2026-04-02T07:25:30Z","status":"public","type":"journal_article","article_number":"acsphotonics.5c02865","_id":"65316","user_id":"30525","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"citation":{"ieee":"H.

Conducted at Paderborn University, this study examined how students’ sense of belonging to physics influences their academic outcomes in an introductory experimental physics course. Additionally, we investigated how physics students’ engagement in the Physiktreff—a holistic support program for first-year physics students to help them cope with academic and social challenges during their studies—impacts the development of their sense of belonging to physics over time. Our findings indicated that students with a stronger sense of belonging to physics performed better academically. Moreover, students who actively participated in the support program experienced a positive shift in their sense of belonging to physics. However, our findings also revealed that physics students with a higher initial sense of belonging to physics tended to experience a decline in their sense of belonging to physics during their first semester. These results underscore the importance of fostering a sense of belonging to physics within higher education, particularly during the introductory phase of students’ studies.

In der fachdidaktischen Forschung liegt daher bereits seit längerem ein Fokus auf der Analyse des FDW, wobei mittlerweile vor allem Auswirkungen auf die Handlungsqualität und auf Lernergebnisse in den Blick genommen werden. Nach wie vor stellt aber auch die empirisch fundierte inhaltliche Beschreibung des FDW sowie der Transfer entwickelter FDW-Testverfahren auf Basis von Testinstrumenten mit offenem Antwortformat in die Ausbildungspraxis ein Forschungsdesiderat dar. In diesem Dissertationsprojekt werden daher auf Basis eines Datensatzes von 846 Bearbeitungen eines FDW-Testinstruments im Fach Physik (1) projektübergreifende FDW-Kompetenzniveaus auf Basis von Item-Response-Modellierungen exploriert, (2) nicht-hierarchische FDW-Kompetenzprofile auf Basis von (probabilistischen) Cluster- und Textanalysen beschrieben und (3) ein vollständig automatisiertes FDW-Assessment-System auf Basis von Machine Learning entwickelt. Dabei wurden insbesondere kognitive Anforderungskategorien als Subskalen des verwendeten Testinstruments betrachtet. Das Assessment-System wurde dabei auf Basis dieser und weiterer Subskalen sowie anhand der Zuordnung von Proband:innen zu den Kompetenzprofilen evaluiert und zeigte sowohl relativ zur Interrater-Übereinstimmung als auch absolut betrachtet hohe Performanzwerte.","lang":"ger"},{"text":"Pedagogical Content Knowledge (PCK) is one of the central elements of the professional knowledge of (prospective) teachers. Its relevance is theoretically established and empirically shown multiple times. PCK has therefore been analyzed continuously in education research, currently with a particular emphasis on its impact on the quality of teaching and directly on learning outcomes. However, there is still a lack of detailed empirically backed descriptions of the intricacies of PCK and of methodologies for translating developed PCK assessment procedures based on open-ended questionnaires into educational practice. In this dissertation project, therefore, three objectives are pursued, based on a dataset of 846 responses to a physics PCK test instrument. First, cross-project PCK competency levels are explored based on item response modeling. Second, non-hierarchical PCK competency profiles are described based on (probabilistic) cluster and text analyses. Third, a fully automated FDW assessment system based on Machine Learning is developed. In particular, cognitive requirement categories were considered as subscales of the test instrument used. The assessment system was evaluated based on these and other subscales, as well as the assignment of respondents to the competency profiles, and demonstrated high performance values both in relation to inter-rater agreement and in absolute terms.","lang":"eng"}],"status":"public"}]
