In this work, we present a dual amplitude holographic scheme based on the photon sieve principle, which is then combined with a phase hologram by utilizing the Pancharatnam–Berry phase. We demonstrate that two types of apertures, rectangular and square shapes in a gold film filled with silicon nanoantennas are sufficient to create two amplitude holograms at two different wavelengths in the visible, multiplexed with an additional phase-only hologram. The nanoantennas are tailored to adjust the spectral transmittance of the apertures, enabling the wavelength sensitivity. The phase-only hologram is implemented by utilizing the anisotropic rectangular structure. Interestingly, such three holograms have quantitative mathematical correlations with each other. Thus, the flexibility of polarization and wavelength channels can be utilized with custom-tailored features to achieve such amplitude and phase holography simultaneously without sacrificing any space-bandwidth product. The present scheme has the potential to store different pieces of information which can be displayed separately by switching the wavelength or the polarization state of the reading light beam.","lang":"eng"}],"publication":"Nanophotonics","title":"A wavelength and polarization selective photon sieve for holographic applications","publisher":"De Gruyter","date_created":"2021-10-28T07:15:52Z","year":"2021","quality_controlled":"1","issue":"18"},{"type":"journal_article","status":"public","user_id":"49683","department":[{"_id":"15"},{"_id":"61"},{"_id":"230"}],"project":[{"_id":"53","name":"TRR 142"}],"_id":"23728","file_date_updated":"2021-09-07T07:41:04Z","article_type":"original","publication_status":"published","has_accepted_license":"1","publication_identifier":{"issn":["2515-7647"]},"citation":{"mla":"Höpker, Jan Philipp, et al. “Integrated Superconducting Nanowire Single-Photon Detectors on Titanium in-Diffused Lithium Niobate Waveguides.” <i>Journal of Physics: Photonics</i>, vol. 3, 2021, p. 034022, doi:<a href=\"https://doi.org/10.1088/2515-7647/ac105b\">10.1088/2515-7647/ac105b</a>.","short":"J.P.

So far, the most commonly used experimental techniques for this purpose have been all-optical spectroscopy methods that, however, are generally averaging in momentum space. Additional information can be gained by angle-resolved photoelectron spectroscopy (ARPES), which measures the electronic structure with momentum resolution. Here we report on the use of extremely low-energy ARPES (photon energy ~ 7 eV) to increase depth sensitivity and access buried QW states, located at 3 nm and 6 nm below the surface of cubic-GaN/AlN and GaAs/AlGaAs heterostructures, respectively. We find that the QW states in cubic-GaN/AlN can indeed be observed, but not their energy dispersion, because of the high surface roughness. The GaAs/AlGaAs QW states, on the other hand, are buried too deep to be detected by extremely low-energy ARPES. Since the sample surface is much flatter, the ARPES spectra of the GaAs/AlGaAs show distinct features in momentum space, which can be reconducted to the band structure of the topmost surface layer of the QW structure.

The antennas considered here are composed of two simple building blocks, a director and a reflector, deposited on a glass substrate. Colloidal quantum dots placed in the feed gap between the two elements serve as internal light source. The emission profile of the antenna is mainly formed by the director while the reflector suppresses backward emission. Systematic studies of the director dimensions as well as variation of antenna material show that the effective refractive index of the director primarily governs the far-field emission pattern. Below cut off, i.e., if the director’s effective refractive index is smaller than the refractive index of the substrate, the main lobe results from leaky wave emission along the director. In contrast, if the director supports a guided mode, the emission predominately originates from the end facet of the director.","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["tet_topic_opticalantenna"],"ddc":["530"],"issue":"10","year":"2021","date_created":"2021-04-29T06:56:40Z","title":"Dielectric travelling wave antennas for directional light emission"},{"date_created":"2021-10-26T12:42:16Z","author":[{"last_name":"Luo","orcid":"0000-0003-1008-4976","full_name":"Luo, Kai Hong","id":"36389","first_name":"Kai Hong"},{"orcid":"0000-0001-5718-358X","last_name":"Santandrea","full_name":"Santandrea, Matteo","id":"55095","first_name":"Matteo"},{"id":"42777","full_name":"Stefszky, Michael","last_name":"Stefszky","first_name":"Michael"},{"first_name":"Jan","orcid":"0000-0002-5844-3205","last_name":"Sperling","full_name":"Sperling, Jan","id":"75127"},{"full_name":"Massaro, Marcello","id":"59545","last_name":"Massaro","orcid":"0000-0002-2539-7652","first_name":"Marcello"},{"first_name":"Alessandro","full_name":"Ferreri, Alessandro","id":"65609","last_name":"Ferreri"},{"first_name":"Polina","id":"60286","full_name":"Sharapova, Polina","last_name":"Sharapova"},{"first_name":"Harald","last_name":"Herrmann","full_name":"Herrmann, Harald","id":"216"},{"last_name":"Silberhorn","full_name":"Silberhorn, Christine","id":"26263","first_name":"Christine"}],"date_updated":"2023-04-20T15:08:25Z","doi":"10.1103/physreva.104.043707","title":"Quantum optical coherence: From linear to nonlinear interferometers","publication_status":"published","publication_identifier":{"issn":["2469-9926","2469-9934"]},"citation":{"apa":"Luo, K.

However, the underlying collision dynamics behind solid HHG is still intensively debated and no direct mapping relationship between the collision dynamics with band structure has been built. Here, we show that the electron and its associated hole can be elastically scattered by neighboring atoms when their wavelength approaches the atomic size. We reveal that the elastic scattering of electron/hole from neighboring atoms can dramatically influence the electron recombination with its left-behind hole, which turns out to be the fundamental reason for the anisotropic interband HHG observed recently in bulk crystals. Our findings link the electron/hole backward scattering with Van Hove singularities and forward scattering with critical lines in the band structure and thus build a clear mapping between the band structure and the harmonic spectrum. Our work provides a unifying picture for several seemingly unrelated experimental observations and theoretical predictions, including the anisotropic harmonic emission in MgO, the atomic-like recollision mechanism of solid HHG, and the delocalization of HHG in ZnO. This strongly improved understanding will pave the way for controlling the solid-state HHG and visualizing the structure-dependent electron dynamics in solids.</jats:p>"}],"publication":"Ultrafast Science","type":"journal_article","language":[{"iso":"eng"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"35"}],"user_id":"16199","_id":"37331","project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"_id":"53","name":"TRR 142: TRR 142"},{"name":"TRR 142 - A: TRR 142 - Project Area A","_id":"54"},{"name":"TRR 142 - A7: TRR 142 - Subproject A7","_id":"64"}]},{"date_updated":"2023-04-21T11:14:19Z","publisher":"Springer Science and Business Media LLC","volume":12,"date_created":"2023-01-18T11:47:55Z","author":[{"first_name":"Daniel","id":"38175","full_name":"Berghoff, Daniel","last_name":"Berghoff"},{"last_name":"Bühler","full_name":"Bühler, Johannes","first_name":"Johannes"},{"first_name":"Mischa","full_name":"Bonn, Mischa","last_name":"Bonn"},{"first_name":"Alfred","full_name":"Leitenstorfer, Alfred","last_name":"Leitenstorfer"},{"first_name":"Torsten","id":"344","full_name":"Meier, Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072"},{"full_name":"Kim, Heejae","last_name":"Kim","first_name":"Heejae"}],"title":"Low-field onset of Wannier-Stark localization in a polycrystalline hybrid organic inorganic perovskite","doi":"10.1038/s41467-021-26021-4","publication_identifier":{"issn":["2041-1723"]},"publication_status":"published","issue":"1","year":"2021","intvolume":"        12","citation":{"short":"D.

Its polycrystalline nature is not detrimental to the optical switching performance of the material, since the least dispersive direction of the band structure dominates the contribution to the optical response, which favors low-cost fabrication.

In this study, a variety of electron polarons, namely free, bound, and bipolarons, are analyzed using first-principles calculations. We perform a full structural optimization based on density-functional theory for selected intrinsic defects with special attention to the role of symmetry-breaking distortions that lower the total energy. The cations hosting the various polarons relax to a different degree, with a larger relaxation corresponding to a larger gap between the defect level and the conduction-band edge. The projected density of states reveals that the polaron states are formerly empty Nb 4d states lowered into the band gap. Optical absorption spectra are derived within the independent-particle approximation, corrected by the GW approximation that yields a wider band gap and by including excitonic effects within the Bethe-Salpeter equation. Comparing the calculated spectra with the density of states, we find that the defect peak observed in the optical absorption stems from transitions between the defect level and a continuum of empty Nb 4d states. Signatures of polarons are further analyzed in the reflectivity and other experimentally measurable optical coefficients."}],"date_created":"2021-05-03T09:36:13Z","publisher":"MDPI","title":"Electron polarons in lithium niobate: Charge localization, lattice deformation, and optical response","quality_controlled":"1","year":"2021"},{"type":"conference","publication":"Ultrafast Phenomena and Nanophotonics XXV","status":"public","editor":[{"first_name":"Markus","last_name":"Betz","full_name":"Betz, Markus"},{"last_name":"Elezzabi","full_name":"Elezzabi, Abdulhakem Y.","first_name":"Abdulhakem Y."}],"user_id":"16199","series_title":"SPIE Proceedings","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"623"},{"_id":"35"}],"project":[{"name":"TRR 142","_id":"53"},{"name":"TRR 142 - Project Area A","_id":"54"},{"_id":"59","name":"TRR 142 - Subproject A2"},{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"_id":"23474","language":[{"iso":"eng"}],"article_number":"116840X","publication_status":"published","citation":{"ama":"Reichelt M, Rose H, Kosarev AN, et al.

In this work, we provide a rigorous theoretical description of the spatial properties of bright squeezed light in the presence of strong anisotropy. We investigate a single crystal and a system of two crystals with an air gap (corresponding to a nonlinear SU(1,1) interferometer) and demonstrate the generation of bright correlated twin-beams in such configurations at high gain due to anisotropy. We explore the mode structure of the generated light and show how anisotropy, together with crystal spacing, can be used for radiation shaping.</jats:p>"}],"department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"35"}],"user_id":"16199","_id":"37334","project":[{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"TRR 142: TRR 142","_id":"53"},{"name":"TRR 142 - C: TRR 142 - Project Area C","_id":"56"},{"_id":"76","name":"TRR 142 - C6: TRR 142 - Subproject C6"}],"language":[{"iso":"eng"}],"keyword":["Atomic and Molecular Physics","and Optics"],"issue":"14","publication_identifier":{"issn":["1094-4087"]},"publication_status":"published","intvolume":"        29","page":"21876-21890","citation":{"short":"M.

Defect trapped polarons and bipolarons are found to strongly enhance the nonlinear susceptibility of the material, in particular if localized at NbV–VLi defect pairs. This is essentially a consequence of the polaronic excitation resulting in relaxation-induced gap states. The occupation of these levels leads to strongly enhanced χ(2) coefficients and allows for the spatial and transient modification of the second-harmonic generation of macroscopic samples."}],"publication":"Physical Review B","language":[{"iso":"eng"}],"ddc":["530"],"external_id":{"arxiv":["2106.01145"],"isi":["000720931400007"]},"page":"174110","intvolume":"       104","citation":{"apa":"Kozub, A.
