Entangled systems with a large number of photons are of great interest at present because they provide a platform for streaming technologies based on photonics. In this paper we present a device which operates with four-photons and based on the Hong–Ou–Mandel interference. The presented device allows to maximize the degree of spatial entanglement and generate the highly entangled four-dimensional Bell states. Furthermore, the use of the interferometer in different regimes leads to fast interference fringes in the coincidence probability with period of oscillations twice smaller than the pump wavelength. We have a good agreement between theoretical simulations and experimental results.</jats:p>","lang":"eng"}],"department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"288"},{"_id":"230"},{"_id":"429"},{"_id":"35"}],"user_id":"16199","_id":"40381","project":[{"_id":"53","name":"TRR 142: TRR 142"},{"_id":"56","name":"TRR 142 - C: TRR 142 - Project Area C"},{"_id":"72","name":"TRR 142 - C2: TRR 142 - Subproject C2"}],"language":[{"iso":"eng"}],"keyword":["Electrical and Electronic Engineering","Physics and Astronomy (miscellaneous)","Materials Science (miscellaneous)","Atomic and Molecular Physics","and Optics"],"article_number":"045020"},{"status":"public","type":"journal_article","publication":"Physical Review Materials","language":[{"iso":"eng"}],"user_id":"14","department":[{"_id":"230"},{"_id":"429"}],"_id":"23831","citation":{"apa":"Baron, E., Goldhahn, R., Deppe, M., As, D.

However, high dissipative losses and inevitable thermal heating limit their applicability in nonlinear nanophotonics. All-dielectric metasurfaces, supporting both electric and magnetic Mie-type resonances in their nanostructures, have appeared as a promising alternative to nonlinear plasmonics. High-index dielectric nanostructures, allowing additional magnetic resonances, can induce magnetic nonlinear effects, which, along with electric nonlinearities, increase the nonlinear conversion efficiency. In addition, low dissipative losses and high damage thresholds provide an extra degree of freedom for operating at high pump intensities, resulting in a considerable enhancement of the nonlinear processes. We discuss the current state of the art in the intensely developing area of all-dielectric nonlinear nanostructures and metasurfaces, including the role of Mie modes, Fano resonances, and anapole moments for harmonic generation, wave mixing, and ultrafast optical switching. Furthermore, we review the recent progress in the nonlinear phase and wavefront control using all-dielectric metasurfaces. We discuss techniques to realize all-dielectric metasurfaces for multifunctional applications and generation of second-order nonlinear processes from complementary metal–oxide–semiconductor-compatible materials."}],"file":[{"relation":"main_file","success":1,"content_type":"application/pdf","file_name":"AdvPhoton_2019.pdf","file_id":"15330","access_level":"closed","file_size":5275552,"creator":"zentgraf","date_created":"2019-12-14T14:24:36Z","date_updated":"2019-12-14T14:24:36Z"}],"ddc":["530"],"language":[{"iso":"eng"}],"quality_controlled":"1","issue":"2","year":"2019","date_created":"2019-04-04T06:20:14Z","title":"Nonlinear optics in all-dielectric nanoantennas and metasurfaces: a review"},{"date_created":"2019-07-15T07:55:26Z","title":"Nonreciprocal Asymmetric Polarization Encryption by Layered Plasmonic Metasurfaces","issue":"6","quality_controlled":"1","year":"2019","external_id":{"pmid":["31050899"]},"language":[{"iso":"eng"}],"publication":"Nano Letters","abstract":[{"lang":"eng","text":"As flexible optical devices that can manipulate the phase and amplitude of light, metasurfaces would clearly benefit from directional optical properties. However, single layer metasurface systems consisting of two-dimensional nanoparticle arrays exhibit only a weak spatial asymmetry perpendicular to the surface and therefore have mostly symmetric transmission features. Here, we present a metasurface design principle for nonreciprocal polarization encryption of holographic images. Our approach is based on a two-layer plasmonic metasurface design that introduces a local asymmetry and generates a bidirectional functionality with full phase and amplitude control of the transmitted light. The encoded hologram is designed to appear in a particular linear cross-polarization channel, while it is disappearing in the reverse propagation direction. Hence, layered metasurface systems can feature asymmetric transmission with full phase and amplitude control and therefore expand the design freedom in nanoscale optical devices toward asymmetric information processing and security features for anticounterfeiting applications."}],"author":[{"first_name":"Daniel","full_name":"Frese, Daniel","last_name":"Frese"},{"last_name":"Wei","full_name":"Wei, Qunshuo","first_name":"Qunshuo"},{"last_name":"Wang","full_name":"Wang, Yongtian","first_name":"Yongtian"},{"full_name":"Huang, Lingling","last_name":"Huang","first_name":"Lingling"},{"last_name":"Zentgraf","orcid":"0000-0002-8662-1101","id":"30525","full_name":"Zentgraf, Thomas","first_name":"Thomas"}],"volume":19,"date_updated":"2022-01-06T06:51:13Z","doi":"10.1021/acs.nanolett.9b01298","publication_status":"published","publication_identifier":{"issn":["1530-6984","1530-6992"]},"pmid":"1","citation":{"mla":"Frese, Daniel, et al. “Nonreciprocal Asymmetric Polarization Encryption by Layered Plasmonic Metasurfaces.” <i>Nano Letters</i>, vol. 19, no. 6, 2019, pp. 3976–80, doi:<a href=\"https://doi.org/10.1021/acs.nanolett.9b01298\">10.1021/acs.nanolett.9b01298</a>.","bibtex":"@article{Frese_Wei_Wang_Huang_Zentgraf_2019, title={Nonreciprocal Asymmetric Polarization Encryption by Layered Plasmonic Metasurfaces}, volume={19}, DOI={<a href=\"https://doi.org/10.1021/acs.nanolett.9b01298\">10.1021/acs.nanolett.9b01298</a>}, number={6}, journal={Nano Letters}, author={Frese, Daniel and Wei, Qunshuo and Wang, Yongtian and Huang, Lingling and Zentgraf, Thomas}, year={2019}, pages={3976–3980} }","short":"D.

Starting from the relaxed atomic geometries, we analyze the influence of self-energy corrections on the electronic band structure within the GW approximation. We find that quasiparticle shifts widen the direct (indirect) band gap by 1.21 (1.44), 1.58 (1.55), and 1.67 (1.64) eV for the cubic, tetragonal, and orthorhombic phase, respectively. By solving the Bethe-Salpeter equation, we obtain the linear dielectric function with excitonic and local-field effects, which turn out to be essential for good agreement with experimental data. From our results, we extract an exciton binding energy of 0.6, 0.5, and 0.5 eV for the cubic, tetragonal, and orthorhombic phase, respectively. Furthermore, we investigate the nonlinear second-harmonic generation (SHG) both theoretically and experimentally. The frequency-dependent second-order polarization tensor of orthorhombic KNbO3 is measured for incoming photon energies between 1.2 and 1.6 eV. In addition, calculations within the independent-(quasi)particle approximation are performed for the tetragonal and orthorhombic phase. The novel experimental data are in excellent agreement with the quasiparticle calculations and resolve persistent discrepancies between earlier experimental measurements and ab initio results reported in the literature.","lang":"eng"}],"publication":"Physical Review Materials","title":"Quasiparticle and excitonic effects in the optical response of KNbO3","date_created":"2019-05-29T06:55:29Z","publisher":"American Physical Society","year":"2019","issue":"5","quality_controlled":"1"},{"doi":"10.1126/sciadv.aat1451","title":"Nonlinear integrated quantum electro-optic circuits","volume":5,"date_created":"2023-01-18T10:35:19Z","author":[{"first_name":"Kai-Hong","id":"36389","full_name":"Luo, Kai-Hong","last_name":"Luo","orcid":"0000-0003-1008-4976"},{"id":"38161","full_name":"Brauner, Sebastian","last_name":"Brauner","first_name":"Sebastian"},{"first_name":"Christof","last_name":"Eigner","orcid":"https://orcid.org/0000-0002-5693-3083","id":"13244","full_name":"Eigner, Christof"},{"first_name":"Polina","full_name":"Sharapova, Polina","id":"60286","last_name":"Sharapova"},{"full_name":"Ricken, Raimund","last_name":"Ricken","first_name":"Raimund"},{"full_name":"Meier, Torsten","id":"344","last_name":"Meier","orcid":"0000-0001-8864-2072","first_name":"Torsten"},{"last_name":"Herrmann","full_name":"Herrmann, Harald","id":"216","first_name":"Harald"},{"id":"26263","full_name":"Silberhorn, Christine","last_name":"Silberhorn","first_name":"Christine"}],"date_updated":"2023-04-21T11:25:39Z","publisher":"American Association for the Advancement of Science (AAAS)","intvolume":"         5","citation":{"short":"K.-H.

Within the independent-particle approximation an electronic transport gap of 2.97 eV is obtained that widens to about 5.23 eV when quasiparticle effects are included using the GW approximation. The optical response is shown to be strongly anisotropic due to (i) the slight asymmetry of the TiO6 octahedra in the (001) plane and (ii) their anisotropic distribution along the [001] and [100] directions. In addition, excitonic effects are very important: The solution of the Bethe–Salpeter equation indicates exciton binding energies of the order of 1.5 eV. Calculations that include both quasiparticle and excitonic effects are in good agreement with the measured reflectivity.","lang":"eng"}],"publication":"Journal of Physics: Materials","doi":"10.1088/2515-7639/ab29ba","volume":2,"author":[{"last_name":"Neufeld","id":"23261","full_name":"Neufeld, Sergej","first_name":"Sergej"},{"last_name":"Bocchini","orcid":"https://orcid.org/0000-0002-2134-3075","full_name":"Bocchini, Adriana","id":"58349","first_name":"Adriana"},{"orcid":"0000-0002-4476-223X","last_name":"Gerstmann","id":"171","full_name":"Gerstmann, Uwe","first_name":"Uwe"},{"first_name":"Arno","full_name":"Schindlmayr, Arno","id":"458","orcid":"0000-0002-4855-071X","last_name":"Schindlmayr"},{"id":"468","full_name":"Schmidt, Wolf Gero","orcid":"0000-0002-2717-5076","last_name":"Schmidt","first_name":"Wolf Gero"}],"date_updated":"2023-04-21T11:36:12Z","oa":"1","page":"045003","intvolume":"         2","citation":{"ama":"Neufeld S, Bocchini A, Gerstmann U, Schindlmayr A, Schmidt WG.
