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."}],"keyword":["tet_topic_opticalantenna","tet_topic_numerics","tet_topic_meta"],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["2304-6732"]},"citation":{"chicago":"Metzner, Dominik, Jens Potthoff, Thomas Zentgraf, and Jens Förstner. “Approximating Incoherent Monochromatic Light Sources in FDTD Simulations.” <i>Photonics</i> 13, no. 2 (2026). <a href=\"https://doi.org/10.3390/photonics13020128\">https://doi.org/10.3390/photonics13020128</a>.","ieee":"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"}],"publication":"ACS Omega","main_file_link":[{"url":"https://pubs.acs.org/doi/abs/10.1021/acsomega.5c09476","open_access":"1"}],"doi":"10.1021/acsomega.5c09476","oa":"1","date_updated":"2026-03-10T08:27:15Z","author":[{"first_name":"Naresh","last_name":"Killi","full_name":"Killi, Naresh"},{"first_name":"Amit","full_name":"Kumar, Amit","last_name":"Kumar"},{"full_name":"Nebhani, Leena","last_name":"Nebhani","first_name":"Leena"},{"first_name":"Franziska","full_name":"Obst, Franziska","last_name":"Obst"},{"first_name":"Andreas","last_name":"Richter","full_name":"Richter, Andreas"},{"first_name":"Bernhard","last_name":"Reineke Matsudo","full_name":"Reineke Matsudo, Bernhard"},{"id":"30525","full_name":"Zentgraf, Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","first_name":"Thomas"},{"full_name":"Kuckling, Dirk","id":"287","last_name":"Kuckling","first_name":"Dirk"}],"volume":11,"citation":{"apa":"Killi, N., Kumar, A., Nebhani, L., Obst, F., Richter, A., Reineke Matsudo, B., Zentgraf, T., &#38; Kuckling, D.

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"}],"publisher":"Wiley","date_created":"2025-10-06T05:42:21Z","title":"Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation","quality_controlled":"1","year":"2026"},{"publication_identifier":{"issn":["0028-0836","1476-4687"]},"publication_status":"published","issue":"8096","year":"2026","page":"345-352","intvolume":"       649","citation":{"short":"S.

However, the polarization DoF is intrinsically limited to two by\r\northogonality, which causes unavoidable crosstalk and often forces position multiplexing, where different\r\nchannels are assigned to distinct spatial locations to suppress crosstalk. 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. The polarization projection method breaks the DoF limitation\r\nof polarization multiplexing, opening a path toward high-dimensional photonic information encoding for\r\ncommunication, encryption, and imaging."}],"publication":"Advanced Photonics","title":"Increasing the design degree of freedom for polarization through multilayer synchronous polarization projection","date_created":"2026-03-16T07:17:52Z","publisher":"SPIE-Intl Soc Optical Eng","year":"2026","issue":"02","quality_controlled":"1"},{"article_number":"acsphotonics.5c02865","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"user_id":"30525","_id":"65316","status":"public","type":"journal_article","doi":"10.1021/acsphotonics.5c02865","main_file_link":[{"url":"https://arxiv.org/abs/2512.14452","open_access":"1"}],"author":[{"full_name":"Wetter, Helene","last_name":"Wetter","first_name":"Helene"},{"id":"69187","full_name":"Wingenbach, Jan","last_name":"Wingenbach","first_name":"Jan"},{"last_name":"Rehberg","full_name":"Rehberg, Falk","first_name":"Falk"},{"full_name":"Gao, Wenlong","last_name":"Gao","first_name":"Wenlong"},{"full_name":"Schumacher, Stefan","id":"27271","orcid":"0000-0003-4042-4951","last_name":"Schumacher","first_name":"Stefan"},{"id":"30525","full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","last_name":"Zentgraf","first_name":"Thomas"}],"oa":"1","date_updated":"2026-04-02T07:31:24Z","citation":{"ieee":"H.

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."}],"publication":"ACS Photonics","title":"Polarization- and Wave-Vector Selective Optical Metasurface with Near-Field Coupling","date_created":"2026-04-02T07:25:30Z","publisher":"American Chemical Society (ACS)","year":"2026","quality_controlled":"1"},{"language":[{"iso":"eng"}],"user_id":"30525","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"_id":"65357","status":"public","editor":[{"first_name":"Manijeh","last_name":"Razeghi","full_name":"Razeghi, Manijeh"},{"full_name":"Khodaparast, Giti A.","last_name":"Khodaparast","first_name":"Giti A."},{"full_name":"Vitiello, Miriam S.","last_name":"Vitiello","first_name":"Miriam S."}],"type":"conference","publication":"Quantum Sensing and Nano Electronics and Photonics XXII","doi":"10.1117/12.3095416","title":"Fabrication of uniform, high-field-enhanced plasmonic satellite clusters using multidewetting","author":[{"first_name":"Minjun","full_name":"Kim, Minjun","last_name":"Kim"},{"first_name":"Vasanthan","last_name":"Devaraj","full_name":"Devaraj, Vasanthan"},{"first_name":"Hyeon-Seok","full_name":"Seo, Hyeon-Seok","last_name":"Seo"},{"full_name":"Eom, Seongjae","last_name":"Eom","first_name":"Seongjae"},{"first_name":"Jeong-Su","last_name":"Lee","full_name":"Lee, Jeong-Su"},{"full_name":"Lee, Donghan","last_name":"Lee","first_name":"Donghan"},{"first_name":"Thomas","id":"30525","full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","last_name":"Zentgraf"},{"full_name":"Lee, Jong-Min","last_name":"Lee","first_name":"Jong-Min"},{"first_name":"Min Yong","full_name":"Jeon, Min Yong","last_name":"Jeon"}],"date_created":"2026-04-07T04:29:28Z","date_updated":"2026-04-07T04:30:07Z","publisher":"SPIE","citation":{"ama":"Kim M, Devaraj V, Seo H-S, et al.

The chemical and electronic properties of AlInP (001) depend on its surface reconstruction, which impacts its interaction with electrolytes in PEC applications and passivation layers. This study investigates AlInP (001) surface reconstructions using density functional theory and experimental methods. Phosphorus‐rich (P‐rich) and indium‐rich (In‐rich) AlInP surfaces are prepared with in situ monitoring of the process by reflection anisotropy (RA) spectroscopy and confirmed by low‐energy electron diffraction and photoemission spectroscopy. The experimental RA spectra closely match the theoretical predictions obtained by solving the Bethe–Salpeter equation. It is shown that missing hydrogen on P‐rich surfaces and formation of In–In 1D atomic chains on In‐rich surfaces introduce mid‐gap surface states that pin the Fermi level and induce band bending. Time‐resolved two‐photon photoemission measurements reveal ultrafast near‐surface electron dynamics for both P‐rich and In‐rich surfaces, demonstrating photoexcited electrons reaching the surface conduction band minimum and relaxing to mid‐gap surface states on about hundreds of fs. This work provides the most extensive AlInP surface analysis to date, allowing for more targeted surface and interface engineering, which is crucial for the optimization and design of III‐V heterostructures.</jats:p>"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"230"},{"_id":"27"},{"_id":"295"}],"user_id":"79462","_id":"60580","language":[{"iso":"eng"}],"publication_identifier":{"issn":["1616-301X","1616-3028"]},"publication_status":"published","citation":{"mla":"Zare Pour, Mohammad Amin, et al. “Exploring Electronic States and Ultrafast Electron Dynamics in AlInP Window Layers: The Role of Surface Reconstruction.” <i>Advanced Functional Materials</i>, Wiley, 2025, doi:<a href=\"https://doi.org/10.1002/adfm.202423702\">10.1002/adfm.202423702</a>.","bibtex":"@article{Zare Pour_Shekarabi_Ruiz Alvarado_Diederich_Gao_Paszuk_Moritz_Jaegermann_Friedrich_van de Krol_et al._2025, title={Exploring Electronic States and Ultrafast Electron Dynamics in AlInP Window Layers: The Role of Surface Reconstruction}, DOI={<a href=\"https://doi.org/10.1002/adfm.202423702\">10.1002/adfm.202423702</a>}, journal={Advanced Functional Materials}, publisher={Wiley}, author={Zare Pour, Mohammad Amin and Shekarabi, Sahar and Ruiz Alvarado, Isaac Azahel and Diederich, Jonathan and Gao, Yuyings and Paszuk, Agnieszka and Moritz, Dominik C. and Jaegermann, Wolfram and Friedrich, Dennis and van de Krol, Roel and et al.}, year={2025} }","short":"M.A. Zare Pour, S.

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.

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"}],"status":"public","publisher":"Wiley","date_updated":"2025-09-18T11:06:59Z","volume":12,"date_created":"2025-09-18T11:03:16Z","author":[{"first_name":"Jonathan","last_name":"Diederich","full_name":"Diederich, Jonathan"},{"first_name":"Agnieszka","full_name":"Paszuk, Agnieszka","last_name":"Paszuk"},{"orcid":"0000-0002-4710-1170","last_name":"Ruiz Alvarado","full_name":"Ruiz Alvarado, Isaac Azahel","id":"79462","first_name":"Isaac Azahel"},{"first_name":"Marvin","full_name":"Krenz, Marvin","last_name":"Krenz"},{"full_name":"Zare Pour, Mohammad Amin","last_name":"Zare Pour","first_name":"Mohammad Amin"},{"last_name":"Babu","full_name":"Babu, Diwakar Suresh","first_name":"Diwakar Suresh"},{"last_name":"Velazquez Rojas","full_name":"Velazquez Rojas, Jennifer","first_name":"Jennifer"},{"first_name":"Christian","last_name":"Höhn","full_name":"Höhn, Christian"},{"full_name":"Gao, Yuying","last_name":"Gao","first_name":"Yuying"},{"full_name":"Schwarzburg, Klaus","last_name":"Schwarzburg","first_name":"Klaus"},{"first_name":"David","full_name":"Ostheimer, David","last_name":"Ostheimer"},{"first_name":"Rainer","full_name":"Eichberger, Rainer","last_name":"Eichberger"},{"first_name":"Wolf Gero","id":"468","full_name":"Schmidt, Wolf Gero","last_name":"Schmidt","orcid":"0000-0002-2717-5076"},{"full_name":"Hannappel, Thomas","last_name":"Hannappel","first_name":"Thomas"},{"first_name":"Roel van","last_name":"de Krol","full_name":"de Krol, Roel van"},{"last_name":"Friedrich","full_name":"Friedrich, Dennis","first_name":"Dennis"}],"title":"Ultrafast Electron Dynamics at the Water‐Modified InP(100) Surface","doi":"10.1002/admi.202500463","publication_identifier":{"issn":["2196-7350","2196-7350"]},"publication_status":"published","issue":"16","year":"2025","intvolume":"        12","citation":{"mla":"Diederich, Jonathan, et al. “Ultrafast Electron Dynamics at the Water‐Modified InP(100) Surface.” <i>Advanced Materials Interfaces</i>, vol. 12, no. 16, e00463, Wiley, 2025, doi:<a href=\"https://doi.org/10.1002/admi.202500463\">10.1002/admi.202500463</a>.","short":"J.

We clarify the theoretical basis for the waveguides with potentially non-diagonal core permittivity. Symmetry classes can be distinguished that differ in their consequences for potential modal degeneracy and polarization conversion. Our rigorous numerical analysis by means of a finite-element solver takes the anisotropy of the lithium niobate cores rigorously into account. We discuss extensive data for effective indices, polarization properties, and hybridization of guided modes, in single- and multimode channels. Scans over the waveguide width and orientation as primary parameters are complemented by a series of illustrations of vectorial mode profiles. These turn out to be essentially complex in cases of X-cut channels at non-crystal-axis-aligned orientations.","lang":"eng"}],"publication":"Optics Continuum","language":[{"iso":"eng"}],"keyword":["tet_topic_waveguide"],"ddc":["530"]}]
