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.

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","doi":"10.1021/acsphotonics.5c02865","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://pubs.acs.org/doi/10.1021/acsphotonics.5c02865"}],"intvolume":"        13","publication_status":"published","date_updated":"2026-04-20T05:09:57Z","author":[{"first_name":"Helene","last_name":"Wetter","full_name":"Wetter, Helene"},{"last_name":"Wingenbach","first_name":"Jan","full_name":"Wingenbach, Jan","id":"69187"},{"last_name":"Rehberg","first_name":"Falk","full_name":"Rehberg, Falk"},{"full_name":"Gao, Wenlong","first_name":"Wenlong","last_name":"Gao"},{"id":"27271","full_name":"Schumacher, Stefan","first_name":"Stefan","orcid":"0000-0003-4042-4951","last_name":"Schumacher"},{"id":"30525","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","first_name":"Thomas","full_name":"Zentgraf, Thomas"}],"publication_identifier":{"issn":["2330-4022","2330-4022"]},"year":"2026","title":"Polarization- and Wave-Vector Selective Optical Metasurface with Near-Field Coupling","external_id":{"arxiv":["2512.14452"]},"quality_controlled":"1","citation":{"chicago":"Wetter, Helene, Jan Wingenbach, Falk Rehberg, Wenlong Gao, Stefan Schumacher, and Thomas Zentgraf. “Polarization- and Wave-Vector Selective Optical Metasurface with Near-Field Coupling.” <i>ACS Photonics</i> 13 (2026): 2128–33. <a href=\"https://doi.org/10.1021/acsphotonics.5c02865\">https://doi.org/10.1021/acsphotonics.5c02865</a>.","short":"H.

We theoretically and experimentally reveal that when the structural symmetry of the meta-atom is incompatible with the lattice symmetry of an array, some generalized nonlinear geometric phases appear, which offers new possibilities for harmonic generation control beyond the accessible symmetries governed by the selection rule. The underlying mechanism is attributed to the modified rotation of the effective principal axis of a dense meta-atom array, where the strong coupling among the units gives rise to a generalized linear geometric phase modulation of the pump light. Therefore, nonlinear geometric phases carried by third-harmonic emissions are the natural result of the wave-mixing process among the modes excited at the fundamental frequency.

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."}],"date_created":"2023-06-13T09:43:25Z","file":[{"date_created":"2023-06-13T09:48:17Z","creator":"fossie","file_id":"45597","content_type":"application/pdf","relation":"main_file","date_updated":"2023-06-13T09:48:17Z","file_name":"2023-06 Hähnel - ACS Photonics - Efficient Modeling and Tailoring of Nonlinear Wavefronts in Dielectric Metasurfaces.pdf","access_level":"open_access","file_size":5382111}],"department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"keyword":["tet_topic_meta"],"type":"journal_article","publication_identifier":{"issn":["2330-4022","2330-4022"]},"author":[{"last_name":"Hähnel","first_name":"David","full_name":"Hähnel, David"},{"id":"158","orcid":"0000-0001-7059-9862","first_name":"Jens","last_name":"Förstner","full_name":"Förstner, Jens"},{"last_name":"Myroshnychenko","first_name":"Viktor","full_name":"Myroshnychenko, Viktor","id":"46371"}],"title":"Efficient Modeling and Tailoring of Nonlinear Wavefronts in Dielectric Metasurfaces","year":"2023","publication_status":"published","date_updated":"2023-06-13T09:49:12Z","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1"}],"doi":"10.1021/acsphotonics.2c01967","citation":{"apa":"Hähnel, D., Förstner, J., &#38; Myroshnychenko, V.

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.","lang":"eng"}],"issue":"3","publication":"ACS Photonics","doi":"10.1021/acsphotonics.1c00882","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://pubs.acs.org/doi/full/10.1021/acsphotonics.1c00882"}],"article_type":"original","intvolume":"         9","publication_status":"published","date_updated":"2022-03-21T07:48:27Z","author":[{"full_name":"Spreyer, Florian","first_name":"Florian","last_name":"Spreyer"},{"last_name":"Mun","first_name":"Jungho","full_name":"Mun, Jungho"},{"last_name":"Kim","first_name":"Hyeohn","full_name":"Kim, Hyeohn"},{"first_name":"Ryeong Myeong","last_name":"Kim","full_name":"Kim, Ryeong Myeong"},{"full_name":"Nam, Ki Tae","first_name":"Ki Tae","last_name":"Nam"},{"first_name":"Junsuk","last_name":"Rho","full_name":"Rho, Junsuk"},{"id":"30525","full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","first_name":"Thomas","last_name":"Zentgraf"}],"publication_identifier":{"issn":["2330-4022","2330-4022"]},"year":"2022","title":"Second Harmonic Optical Circular Dichroism of Plasmonic Chiral Helicoid-III Nanoparticles","oa":"1","external_id":{"arxiv":["arXiv:2202.13594"]},"quality_controlled":"1","citation":{"chicago":"Spreyer, Florian, Jungho Mun, Hyeohn Kim, Ryeong Myeong Kim, Ki Tae Nam, Junsuk Rho, and Thomas Zentgraf. “Second Harmonic Optical Circular Dichroism of Plasmonic Chiral Helicoid-III Nanoparticles.” <i>ACS Photonics</i> 9, no. 3 (2022): 784–792. <a href=\"https://doi.org/10.1021/acsphotonics.1c00882\">https://doi.org/10.1021/acsphotonics.1c00882</a>.","short":"F.

A stroboscopic technique involving surface acoustic waves synchronized to a modelocked optical source allows to time-resolve the dynamical impact of the electromechanically induced perturbation. The surface acoustic wave periodically enhances or decreases the surface ripple of the static grating. Most remarkably, the dynamic surface deformation deliberately modulates the coupler’s efficiency by ±2% during the ∼2 ns acoustic cycle.","lang":"eng"}],"issue":"2","publication":"ACS Photonics","doi":"10.1021/ph400022u","language":[{"iso":"eng"}],"intvolume":"         1","article_type":"original","date_updated":"2022-01-06T07:00:56Z","publication_status":"published","author":[{"last_name":"Ruppert","first_name":"Claudia","full_name":"Ruppert, Claudia"},{"full_name":"Förster, Frederike","first_name":"Frederike","last_name":"Förster"},{"id":"606","full_name":"Zrenner, Artur","first_name":"Artur","last_name":"Zrenner","orcid":"0000-0002-5190-0944"},{"first_name":"Jörg B.","last_name":"Kinzel","full_name":"Kinzel, Jörg B."},{"full_name":"Wixforth, Achim","first_name":"Achim","last_name":"Wixforth"},{"last_name":"Krenner","first_name":"Hubert J.","full_name":"Krenner, Hubert J."},{"full_name":"Betz, Markus","first_name":"Markus","last_name":"Betz"}],"publication_identifier":{"issn":["2330-4022","2330-4022"]},"title":"Radio Frequency Electromechanical Control over a Surface Plasmon Polariton Coupler","year":"2014","citation":{"mla":"Ruppert, Claudia, et al. “Radio Frequency Electromechanical Control over a Surface Plasmon Polariton Coupler.” <i>ACS Photonics</i>, vol. 1, no. 2, American Chemical Society (ACS), 2014, pp. 91–95, doi:<a href=\"https://doi.org/10.1021/ph400022u\">10.1021/ph400022u</a>.","bibtex":"@article{Ruppert_Förster_Zrenner_Kinzel_Wixforth_Krenner_Betz_2014, title={Radio Frequency Electromechanical Control over a Surface Plasmon Polariton Coupler}, volume={1}, DOI={<a href=\"https://doi.org/10.1021/ph400022u\">10.1021/ph400022u</a>}, number={2}, journal={ACS Photonics}, publisher={American Chemical Society (ACS)}, author={Ruppert, Claudia and Förster, Frederike and Zrenner, Artur and Kinzel, Jörg B. and Wixforth, Achim and Krenner, Hubert J. and Betz, Markus}, year={2014}, pages={91–95} }","ama":"Ruppert C, Förster F, Zrenner A, et al.
