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"}],"file":[{"relation":"main_file","success":1,"content_type":"application/pdf","file_name":"2021-04 Leuteritz - Optics Express - Dielectric travelling wave antennas.pdf","access_level":"closed","file_id":"21822","file_size":7464073,"creator":"fossie","date_created":"2021-04-29T06:59:39Z","date_updated":"2021-04-29T06:59:39Z"}],"ddc":["530"],"keyword":["tet_topic_opticalantenna"],"language":[{"iso":"eng"}],"issue":"10","year":"2021","date_created":"2021-04-29T06:56:40Z","title":"Dielectric travelling wave antennas for directional light emission"},{"date_updated":"2023-04-20T15:08:25Z","date_created":"2021-10-26T12:42:16Z","author":[{"first_name":"Kai Hong","id":"36389","full_name":"Luo, Kai Hong","orcid":"0000-0003-1008-4976","last_name":"Luo"},{"first_name":"Matteo","id":"55095","full_name":"Santandrea, Matteo","orcid":"0000-0001-5718-358X","last_name":"Santandrea"},{"last_name":"Stefszky","id":"42777","full_name":"Stefszky, Michael","first_name":"Michael"},{"id":"75127","full_name":"Sperling, Jan","orcid":"0000-0002-5844-3205","last_name":"Sperling","first_name":"Jan"},{"last_name":"Massaro","orcid":"0000-0002-2539-7652","full_name":"Massaro, Marcello","id":"59545","first_name":"Marcello"},{"full_name":"Ferreri, Alessandro","id":"65609","last_name":"Ferreri","first_name":"Alessandro"},{"id":"60286","full_name":"Sharapova, Polina","last_name":"Sharapova","first_name":"Polina"},{"last_name":"Herrmann","full_name":"Herrmann, Harald","id":"216","first_name":"Harald"},{"first_name":"Christine","id":"26263","full_name":"Silberhorn, Christine","last_name":"Silberhorn"}],"title":"Quantum optical coherence: From linear to nonlinear interferometers","doi":"10.1103/physreva.104.043707","publication_identifier":{"issn":["2469-9926","2469-9934"]},"publication_status":"published","year":"2021","citation":{"short":"K.H.

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>","lang":"eng"}],"status":"public","_id":"37331","project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"_id":"53","name":"TRR 142: TRR 142"},{"_id":"54","name":"TRR 142 - A: TRR 142 - Project Area A"},{"name":"TRR 142 - A7: TRR 142 - Subproject A7","_id":"64"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"35"}],"user_id":"16199","language":[{"iso":"eng"}],"publication_identifier":{"issn":["2765-8791"]},"publication_status":"published","year":"2021","intvolume":"      2021","citation":{"chicago":"Zuo, Ruixin, Alexander Trautmann, Guifang Wang, Wolf-Rüdiger Hannes, Shidong Yang, Xiaohong Song, Torsten Meier, Marcelo Ciappina, Huynh Thanh Duc, and Weifeng Yang. “Neighboring Atom Collisions in Solid-State High Harmonic Generation.” <i>Ultrafast Science</i> 2021 (2021). <a href=\"https://doi.org/10.34133/2021/9861923\">https://doi.org/10.34133/2021/9861923</a>.","ieee":"R.

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.","lang":"eng"}],"external_id":{"isi":["000653822700001"]},"language":[{"iso":"eng"}],"ddc":["530"],"quality_controlled":"1","year":"2021","date_created":"2021-05-03T09:36:13Z","publisher":"MDPI","title":"Electron polarons in lithium niobate: Charge localization, lattice deformation, and optical response"},{"doi":"10.1117/12.2576887","title":"Controlling the emission time of photon echoes by optical freezing of exciton dephasing and rephasing in quantum-dot ensembles","volume":11684,"author":[{"last_name":"Reichelt","id":"138","full_name":"Reichelt, Matthias","first_name":"Matthias"},{"id":"55958","full_name":"Rose, Hendrik","orcid":"0000-0002-3079-5428","last_name":"Rose","first_name":"Hendrik"},{"first_name":"Alexander N.","full_name":"Kosarev, Alexander N.","last_name":"Kosarev"},{"first_name":"Sergey V.","last_name":"Poltavtsev","full_name":"Poltavtsev, Sergey V."},{"full_name":"Bayer, Manfred","last_name":"Bayer","first_name":"Manfred"},{"full_name":"Akimov, Ilya A.","last_name":"Akimov","first_name":"Ilya A."},{"full_name":"Schneider, Christian","last_name":"Schneider","first_name":"Christian"},{"last_name":"Kamp","full_name":"Kamp, Martin","first_name":"Martin"},{"full_name":"Höfling, Sven","last_name":"Höfling","first_name":"Sven"},{"first_name":"Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072","full_name":"Meier, Torsten","id":"344"}],"date_created":"2021-08-24T08:46:40Z","date_updated":"2023-04-21T11:20:10Z","intvolume":"     11684","citation":{"mla":"Reichelt, Matthias, et al. “Controlling the Emission Time of Photon Echoes by Optical Freezing of Exciton Dephasing and Rephasing in Quantum-Dot Ensembles.” <i>Ultrafast Phenomena and Nanophotonics XXV</i>, edited by Markus Betz and Abdulhakem Y.

Our scheme is based on optical excitation off resonant to a cavity mode followed by ultrafast control of the electronic states using the time-dependent quantum-confined Stark effect, which then allows for cavity-resonant emission. Our theoretical analysis considers cavity-loss mechanisms, the Stark effect, and phonon-induced dephasing, allowing realistic predictions for finite temperatures.","lang":"eng"}],"publication":"Physical Review B","doi":"10.1103/physrevb.104.085308","volume":104,"author":[{"first_name":"David","full_name":"Bauch, David","last_name":"Bauch"},{"last_name":"Heinze","id":"10904","full_name":"Heinze, Dirk Florian","first_name":"Dirk Florian"},{"first_name":"Jens","last_name":"Förstner","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens","id":"158"},{"first_name":"Klaus","last_name":"Jöns","full_name":"Jöns, Klaus","id":"85353"},{"first_name":"Stefan","orcid":"0000-0003-4042-4951","last_name":"Schumacher","full_name":"Schumacher, Stefan","id":"27271"}],"date_updated":"2023-04-20T15:33:52Z","oa":"1","intvolume":"       104","page":"085308","citation":{"ieee":"D.
