[{"abstract":[{"text":"Light-emitting diodes (LEDs) are becoming increasingly important across various sectors of the lighting industry and are being used more frequently. 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.","lang":"eng"}],"publication":"Photonics","issue":"2","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"},{"_id":"61"}],"type":"journal_article","keyword":["tet_topic_opticalantenna","tet_topic_numerics","tet_topic_meta"],"date_created":"2026-02-02T07:18:03Z","article_type":"original","intvolume":"        13","publication_status":"published","date_updated":"2026-02-02T21:38:34Z","publication_identifier":{"issn":["2304-6732"]},"author":[{"first_name":"Dominik","last_name":"Metzner","full_name":"Metzner, Dominik"},{"full_name":"Potthoff, Jens","first_name":"Jens","last_name":"Potthoff"},{"first_name":"Thomas","orcid":"0000-0002-8662-1101","last_name":"Zentgraf","full_name":"Zentgraf, Thomas","id":"30525"},{"id":"158","full_name":"Förstner, Jens","last_name":"Förstner","first_name":"Jens","orcid":"0000-0001-7059-9862"}],"title":"Approximating Incoherent Monochromatic Light Sources in FDTD Simulations","year":"2026","doi":"10.3390/photonics13020128","language":[{"iso":"eng"}],"article_number":"128","main_file_link":[{"url":"https://www.mdpi.com/2304-6732/13/2/128","open_access":"1"}],"quality_controlled":"1","citation":{"short":"D.

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"}],"date_created":"2026-03-10T08:23:43Z","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"},{"_id":"2"},{"_id":"311"}],"type":"journal_article","author":[{"first_name":"Naresh","last_name":"Killi","full_name":"Killi, Naresh"},{"full_name":"Kumar, Amit","last_name":"Kumar","first_name":"Amit"},{"full_name":"Nebhani, Leena","last_name":"Nebhani","first_name":"Leena"},{"full_name":"Obst, Franziska","last_name":"Obst","first_name":"Franziska"},{"full_name":"Richter, Andreas","last_name":"Richter","first_name":"Andreas"},{"full_name":"Reineke Matsudo, Bernhard","last_name":"Reineke Matsudo","first_name":"Bernhard"},{"last_name":"Zentgraf","first_name":"Thomas","orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas","id":"30525"},{"id":"287","first_name":"Dirk","last_name":"Kuckling","full_name":"Kuckling, Dirk"}],"publication_identifier":{"issn":["2470-1343","2470-1343"]},"year":"2026","title":"Integrating an Organocatalyst into a Polymeric Gel Framework for the Continuous Microflow Baylis–Hillman Reaction","article_type":"original","intvolume":"        11","publication_status":"published","date_updated":"2026-03-10T08:27:15Z","language":[{"iso":"eng"}],"article_number":"14448","main_file_link":[{"open_access":"1","url":"https://pubs.acs.org/doi/abs/10.1021/acsomega.5c09476"}],"doi":"10.1021/acsomega.5c09476"},{"citation":{"bibtex":"@article{Jin_Zentgraf_2026, title={Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation}, volume={38}, DOI={<a href=\"https://doi.org/10.1002/adma.202511823\">10.1002/adma.202511823</a>}, number={e11823}, journal={Advanced Materials}, publisher={Wiley}, author={Jin, Xiao and Zentgraf, Thomas}, year={2026} }","ama":"Jin X, Zentgraf T.

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.","lang":"eng"}],"date_created":"2025-10-06T05:42:21Z","type":"journal_article","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"title":"Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation","year":"2026","publication_identifier":{"issn":["0935-9648","1521-4095"]},"author":[{"first_name":"Xiao","last_name":"Jin","full_name":"Jin, Xiao"},{"id":"30525","last_name":"Zentgraf","first_name":"Thomas","orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas"}],"date_updated":"2026-03-10T08:32:37Z","publication_status":"published","intvolume":"        38","article_type":"original","main_file_link":[{"url":"https://advanced.onlinelibrary.wiley.com/doi/10.1002/adma.202511823","open_access":"1"}],"article_number":"e11823","language":[{"iso":"eng"}],"doi":"10.1002/adma.202511823"},{"user_id":"112030","volume":649,"page":"345-352","_id":"63531","publisher":"Springer Science and Business Media LLC","status":"public","citation":{"bibtex":"@article{Doshi_Güsken_Dijk_Carlström_Ortiz-Cárdenas_Suzuki_Li_Fordyce_Salleo_Melosh_et al._2026, title={Soft photonic skins with dynamic texture and colour control}, volume={649}, DOI={<a href=\"https://doi.org/10.1038/s41586-025-09948-2\">10.1038/s41586-025-09948-2</a>}, number={8096}, journal={Nature}, publisher={Springer Science and Business Media LLC}, author={Doshi, Siddharth and Güsken, Nicholas Alexander and Dijk, Gerwin and Carlström, Johan and Ortiz-Cárdenas, Jennifer E. and Suzuki, Peter and Li, Bohan and Fordyce, Polly M. and Salleo, Alberto and Melosh, Nicholas A. and et al.}, year={2026}, pages={345–352} }","ama":"Doshi S, Güsken NA, Dijk G, et al.

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.

However, optical networks constructed from conventional bulk 2 × 2-beamsplitters encounter inherent scalability issues, as the number of required beamsplitters scales quadratically with the number of optical modes for a fully connected network. Metasurfaces offer a promising route to\r\novercome these constraints. By manipulating light at the wavelength scale, compact optical components with advanced functionalities can be constructed, which address several modes simultaneously. In this work, we design and experimentally utilize a metasurface as a multiport beamsplitter. Furthermore, we realized a multimode interferometer composed of two cascaded metasurfaces. We characterize the individual and cascaded metasurfaces by using classical light, showing controllable splitting ratios through tunable phase relations. We then expand the approach to quantum light, employing single photons to demonstrate second- and third-order photon correlations as well as single photon interference across multiple spatial paths. These results establish metasurface-based multiport beamsplitters as a scalable and reconfigurable platform bridging classical and quantum photonics.

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.

We introduce a paradigm shift using a many‐body plasmonic architecture inspired by statistical mechanics. By moving toward the continuum limit, local geometric variations are statistically averaged out, effectively decoupling optical performance from microscopic disorder. We implement this concept via a lithography‐ and etching‐free, multi‐step dewetting strategy, creating wafer‐scale nanoclusters. This process strategically forms a robust many‐body system by introducing numerous small satellite nanoparticles between larger particles. Crucially, this design achieves a high collective enhancement that surpasses even optimized few‐body systems, despite having larger individual gaps. Under optimized conditions, these substrates exhibit a surface‐enhanced Raman scattering enhancement factor approaching 4 × 10^8 with unprecedented reproducibility (RSD of ∼10%). This scalable, low‐cost concept establishes a practical route toward reproducible wafer‐scale nanophotonic platforms for sensing, spectroscopy, and quantum technologies.","lang":"eng"}],"publication":"Laser &amp; Photonics Reviews","user_id":"30525","_id":"66555","publisher":"Wiley","status":"public","oa":"1","quality_controlled":"1","citation":{"ama":"Kim M, Devaraj V, Seo H, et al.

Here, we present a systematic optical investigation of large‐scale 3D AuNP assemblies fabricated via meniscus‐guided assembly, focusing on the reproducibility, spatial uniformity, and mode evolution of their plasmonic responses. Spatially‐resolved dark‐field scattering measurements reveal that high‐aspect‐ratio AuNP pillars exhibit uniform scattering spectra along their height and across different pillars, despite variations in geometry and structure. Electromagnetic simulations suggest that this robustness arises from a collective many‐particle plasmonic response that remains optically active despite structural perturbations. The corresponding near‐field and surface‐charge distributions remain spatially distributed under representative structural perturbations, consistent with volumetric averaging across the three‐dimensional assembly. Building on this robust platform, we introduce compositional modulation through a core–satellite architecture by incorporating smaller AuNPs. This yields a composition‐dependent spectral redistribution, including the emergence of an additional long‐wavelength spectral feature in the core–satellite assemblies. Wavelength‐dependent surface‐enhanced Raman scattering measurements reveal contrasting responses under 633 and 785 nm excitation, reflecting redistribution of local plasmonic coupling pathways. These results provide process‐enabled guidelines for using meniscus‐guided 3D‐nanoprinting to realize robust nanoparticle assemblies."}],"date_created":"2026-08-03T06:43:03Z","type":"journal_article","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"year":"2026","title":"Spatially Uniform and Defect‐Tolerant Plasmonic Responses in 3D Printed Gold Nanoparticle Assemblies","publication_identifier":{"issn":["1863-8880","1863-8899"]},"author":[{"id":"103814","last_name":"Devaraj","first_name":"Vasanthan","full_name":"Devaraj, Vasanthan"},{"full_name":"Kwak, Sunghyun","first_name":"Sunghyun","last_name":"Kwak"},{"first_name":"Hyeongjip","last_name":"Kim","full_name":"Kim, Hyeongjip"},{"last_name":"Sung","first_name":"Sang‐Keun","full_name":"Sung, Sang‐Keun"},{"full_name":"Lee, Jong‐Min","first_name":"Jong‐Min","last_name":"Lee"},{"full_name":"Zentgraf, Thomas","last_name":"Zentgraf","first_name":"Thomas","orcid":"0000-0002-8662-1101","id":"30525"},{"first_name":"Won‐Geun","last_name":"Kim","full_name":"Kim, Won‐Geun"}],"date_updated":"2026-08-03T06:45:01Z","publication_status":"published","article_type":"original","main_file_link":[{"open_access":"1","url":"https://onlinelibrary.wiley.com/doi/10.1002/lpor.71686"}],"article_number":"e71686","language":[{"iso":"eng"}],"doi":"10.1002/lpor.71686"},{"type":"journal_article","keyword":["tet_topic_opticalantenna"],"department":[{"_id":"61"},{"_id":"230"},{"_id":"623"}],"file":[{"creator":"fossie","embargo_to":"open_access","date_created":"2026-08-19T13:04:15Z","date_updated":"2026-08-19T13:04:15Z","relation":"main_file","embargo":"2027-08-19","access_level":"local","file_size":33382776,"file_name":"2026-08 Farheen - IEEE JSTQE - Efficient_Silicon_Nitride_Quantum_Interconnect_for_Intrinsic_Silicon_Nitride_Single-Photon_Emitters (PREPRINT).pdf","content_type":"application/pdf","file_id":"66745"}],"date_created":"2026-08-19T11:37:05Z","publication":"IEEE Journal of Selected Topics in Quantum Electronics","doi":"10.1109/jstqe.2026.3722063","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2026-08-19T13:07:08Z","year":"2026","title":"Efficient Silicon Nitride Quantum Interconnect for Intrinsic Silicon Nitride Single-Photon Emitters","author":[{"id":"53444","full_name":"Farheen, Henna","last_name":"Farheen","first_name":"Henna","orcid":"0000-0001-7730-3489"},{"first_name":"Yuheng","last_name":"Chen","full_name":"Chen, Yuheng"},{"last_name":"Chen","first_name":"Peigang","full_name":"Chen, Peigang"},{"full_name":"Maan, Pranshu","last_name":"Maan","first_name":"Pranshu"},{"full_name":"Peana, Samuel","last_name":"Peana","first_name":"Samuel"},{"last_name":"Senichev","first_name":"Alexander","full_name":"Senichev, Alexander"},{"full_name":"Shalaev, Vladimir M.","last_name":"Shalaev","first_name":"Vladimir M."},{"first_name":"Alexandra","last_name":"Boltasseva","full_name":"Boltasseva, Alexandra"},{"id":"158","orcid":"0000-0001-7059-9862","first_name":"Jens","last_name":"Förstner","full_name":"Förstner, Jens"},{"full_name":"Kildishev, Alexander V.","last_name":"Kildishev","first_name":"Alexander V."}],"publication_identifier":{"issn":["1077-260X","1558-4542"]},"project":[{"_id":"266","name":"PhoQC: Photonisches Quantencomputing"}],"file_date_updated":"2026-08-19T13:04:15Z","citation":{"mla":"Farheen, Henna, et al. “Efficient Silicon Nitride Quantum Interconnect for Intrinsic Silicon Nitride Single-Photon Emitters.” <i>IEEE Journal of Selected Topics in Quantum Electronics</i>, Institute of Electrical and Electronics Engineers (IEEE), 2026, pp. 1–12, doi:<a href=\"https://doi.org/10.1109/jstqe.2026.3722063\">10.1109/jstqe.2026.3722063</a>.","bibtex":"@article{Farheen_Chen_Chen_Maan_Peana_Senichev_Shalaev_Boltasseva_Förstner_Kildishev_2026, title={Efficient Silicon Nitride Quantum Interconnect for Intrinsic Silicon Nitride Single-Photon Emitters}, DOI={<a href=\"https://doi.org/10.1109/jstqe.2026.3722063\">10.1109/jstqe.2026.3722063</a>}, journal={IEEE Journal of Selected Topics in Quantum Electronics}, publisher={Institute of Electrical and Electronics Engineers (IEEE)}, author={Farheen, Henna and Chen, Yuheng and Chen, Peigang and Maan, Pranshu and Peana, Samuel and Senichev, Alexander and Shalaev, Vladimir M. and Boltasseva, Alexandra and Förstner, Jens and Kildishev, Alexander V.}, year={2026}, pages={1–12} }","ama":"Farheen H, Chen Y, Chen P, et al.

The Hamiltonian term is treated as an integrating factor by forward and backward Fourier transforms, which are here carried out classically. This split allows us to avoid higher-order time integration schemes, to apply a first-order explicit time stepping for the remaining nonlinear NLSE term in a variational algorithm block, and thus to avoid numerical instabilities. We demonstrate that the analytical solution is reproduced with a small root mean square error for a long time interval over which a nonlinear soliton propagates significantly forward in space while keeping its shape. We analyze the accuracy and complexity of the quantum algorithm, the expressibility of the ansatz circuit and compare it with classical approaches. Furthermore, we investigate the influence of algorithm parameters on the accuracy of the results, including the temporal step width and the depth of the quantum circuit.</jats:p>"}],"publication":"Scientific Reports","issue":"1","user_id":"16199","volume":15,"publisher":"Springer Science and Business Media LLC","_id":"61246","status":"public","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"Hochleistungsrechner Noctua in Paderborn","_id":"445"}],"citation":{"apa":"Köcher, N., Rose, H., Bharadwaj, S.

Despite advances in fundamental understanding of water‐exposed surfaces, the detailed time‐ and energy‐resolved behavior of excited electrons remains largely unexplored. Here, the effects of water exposure on the near‐surface electron dynamics of phosphorus‐terminated p(2×2)/c(4×2)‐reconstructed indium phosphide (100) (P‐rich InP) are studied experimentally and matched to theoretical calculations. The P‐rich InP surface, consisting of H‐passivated P‐dimers, serves as a model for other P‐containing III‐V semiconductors such as gallium phosphide (GaP) or aluminum indium phosphide (AlInP). Electron dynamics near the surface are probed with femtosecond resolution using time‐resolved two‐photon photoemission (tr‐2PPE), a pump‐probe spectroscopic technique. Pulsed water exposure preserves electronic states and significantly increases lifetimes at the conduction band minimum (CBM). Density‐functional theory (DFT) calculations attribute these findings to suppression of surface vibrational modes in the top P‐layer by water exposure, reducing electronic transition probabilities of near‐band‐gap surface states. The results suggest that many near‐surface state lifetimes reported in ultra‐high vacuum may change significantly upon electrolyte exposure. These states may thus contribute more strongly to surface reactions than traditionally assumed. Demonstrating this effect for the technologically relevant P‐rich InP surface opens new opportunities in this underexplored area of surface electrochemistry.</jats:p>","lang":"eng"}],"_id":"61351","publisher":"Wiley","user_id":"16199","volume":12,"status":"public","citation":{"ama":"Diederich J, Paszuk A, Ruiz Alvarado IA, et al.
