PVVBs are typically generated through the superposition of perfect vortex beams, which suffer from the limited number of topological charges (TCs). Furthermore, dynamic control of PVVBs is desirable and has not been reported. We propose and experimentally demonstrate hybrid grafted perfect vector vortex beams (GPVVBs) and their dynamic control. Hybrid GPVVBs are generated through the superposition of grafted perfect vortex beams with a multifunctional metasurface. The generated hybrid GPVVBs possess spatially variant rates of polarization change due to the involvement of more TCs. Each hybrid GPVVB includes different GPVVBs in the same beam, adding more design flexibility. Moreover, these beams are dynamically controlled with a rotating half waveplate. The generated dynamic GPVVBs may find applications in the fields where dynamic control is in high demand, including optical encryption, dense data communication, and multiple particle manipulation.","lang":"eng"}],"date_created":"2023-07-06T06:34:37Z","file":[{"file_id":"45869","success":1,"content_type":"application/pdf","relation":"main_file","date_updated":"2023-07-06T06:40:28Z","file_name":"NatureCommun_Ahmed_2023.pdf","file_size":4341041,"access_level":"closed","date_created":"2023-07-06T06:40:28Z","creator":"zentgraf"}],"department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"keyword":["General Physics and Astronomy","General Biochemistry","Genetics and Molecular Biology","General Chemistry","Multidisciplinary"],"type":"journal_article","author":[{"full_name":"Ahmed, Hammad","first_name":"Hammad","last_name":"Ahmed"},{"full_name":"Ansari, Muhammad Afnan","last_name":"Ansari","first_name":"Muhammad Afnan"},{"last_name":"Li","first_name":"Yan","full_name":"Li, Yan"},{"orcid":"0000-0002-8662-1101","last_name":"Zentgraf","first_name":"Thomas","full_name":"Zentgraf, Thomas","id":"30525"},{"full_name":"Mehmood, Muhammad Qasim","first_name":"Muhammad Qasim","last_name":"Mehmood"},{"last_name":"Chen","first_name":"Xianzhong","full_name":"Chen, Xianzhong"}],"publication_identifier":{"issn":["2041-1723"]},"title":"Dynamic control of hybrid grafted perfect vector vortex beams","year":"2023","intvolume":"        14","publication_status":"published","date_updated":"2023-07-06T06:42:10Z","language":[{"iso":"eng"}],"article_number":"3915","main_file_link":[{"open_access":"1"}],"doi":"10.1038/s41467-023-39599-8"},{"citation":{"chicago":"Babel, Silia, Laura Bollmers, Marcello Massaro, Kai Hong Luo, Michael Stefszky, Federico Pegoraro, Philip Held, et al. “Demonstration of Hong-Ou-Mandel Interference in an LNOI Directional Coupler.” <i>Optics Express</i> 31, no. 14 (2023). <a href=\"https://doi.org/10.1364/oe.484126\">https://doi.org/10.1364/oe.484126</a>.","short":"S.

It is advantageous to operate the systems at telecommunication wavelengths and to integrate the setups for these applications in order to improve stability, compactness and scalability. A new promising material platform for integrated quantum optics is lithium niobate on insulator (LNOI). Here, we realise Hong-Ou-Mandel (HOM) interference between telecom photons from an engineered parametric down-conversion source in an LNOI directional coupler. The coupler has been designed and fabricated in house and provides close to perfect balanced beam splitting. We obtain a raw HOM visibility of (93.5 ± 0.7) %, limited mainly by the source performance and in good agreement with off-chip measurements. This lays the foundation for more sophisticated quantum experiments in LNOI.","lang":"eng"}],"issue":"14","publication":"Optics Express","department":[{"_id":"15"},{"_id":"230"},{"_id":"623"},{"_id":"288"}],"type":"journal_article","keyword":["Atomic and Molecular Physics","and Optics"],"date_created":"2023-07-03T14:08:36Z","intvolume":"        31","publication_status":"published","date_updated":"2023-07-05T07:58:31Z","publication_identifier":{"issn":["1094-4087"]},"author":[{"full_name":"Babel, Silia","first_name":"Silia","orcid":"https://orcid.org/0000-0002-1568-2580","last_name":"Babel","id":"63231"},{"id":"61375","first_name":"Laura","last_name":"Bollmers","full_name":"Bollmers, Laura"},{"orcid":"0000-0002-2539-7652","first_name":"Marcello","last_name":"Massaro","full_name":"Massaro, Marcello","id":"59545"},{"id":"36389","full_name":"Luo, Kai Hong","first_name":"Kai Hong","orcid":"0000-0003-1008-4976","last_name":"Luo"},{"id":"42777","last_name":"Stefszky","first_name":"Michael","full_name":"Stefszky, Michael"},{"first_name":"Federico","last_name":"Pegoraro","full_name":"Pegoraro, Federico","id":"88928"},{"full_name":"Held, Philip","first_name":"Philip","last_name":"Held","id":"68236"},{"id":"216","last_name":"Herrmann","first_name":"Harald","full_name":"Herrmann, Harald"},{"orcid":"https://orcid.org/0000-0002-5693-3083","first_name":"Christof","last_name":"Eigner","full_name":"Eigner, Christof","id":"13244"},{"full_name":"Brecht, Benjamin","orcid":"0000-0003-4140-0556 ","last_name":"Brecht","first_name":"Benjamin","id":"27150"},{"first_name":"Laura","last_name":"Padberg","full_name":"Padberg, Laura","id":"40300"},{"full_name":"Silberhorn, Christine","last_name":"Silberhorn","first_name":"Christine","id":"26263"}],"year":"2023","title":"Demonstration of Hong-Ou-Mandel interference in an LNOI directional coupler","doi":"10.1364/oe.484126","language":[{"iso":"eng"}],"article_number":"23140"},{"issue":"16","publication":"Physical Review B","type":"journal_article","department":[{"_id":"15"},{"_id":"230"}],"date_created":"2023-07-25T08:20:20Z","publication_status":"published","date_updated":"2023-07-25T08:21:13Z","intvolume":"       107","title":"Coherent driving of direct and indirect excitons in a quantum dot molecule","year":"2023","author":[{"last_name":"Bopp","first_name":"Frederik","full_name":"Bopp, Frederik"},{"full_name":"Schall, Johannes","first_name":"Johannes","last_name":"Schall"},{"full_name":"Bart, Nikolai","first_name":"Nikolai","last_name":"Bart"},{"first_name":"Florian","last_name":"Vögl","full_name":"Vögl, Florian"},{"first_name":"Charlotte","last_name":"Cullip","full_name":"Cullip, Charlotte"},{"first_name":"Friedrich","last_name":"Sbresny","full_name":"Sbresny, Friedrich"},{"full_name":"Boos, Katarina","last_name":"Boos","first_name":"Katarina"},{"last_name":"Thalacker","first_name":"Christopher","full_name":"Thalacker, Christopher"},{"last_name":"Lienhart","first_name":"Michelle","full_name":"Lienhart, Michelle"},{"full_name":"Rodt, Sven","first_name":"Sven","last_name":"Rodt"},{"id":"37763","full_name":"Reuter, Dirk","first_name":"Dirk","last_name":"Reuter"},{"first_name":"Arne","last_name":"Ludwig","full_name":"Ludwig, Arne"},{"last_name":"Wieck","first_name":"Andreas D.","full_name":"Wieck, Andreas D."},{"full_name":"Reitzenstein, Stephan","first_name":"Stephan","last_name":"Reitzenstein"},{"full_name":"Müller, Kai","last_name":"Müller","first_name":"Kai"},{"full_name":"Finley, Jonathan J.","first_name":"Jonathan J.","last_name":"Finley"}],"publication_identifier":{"issn":["2469-9950","2469-9969"]},"doi":"10.1103/physrevb.107.165426","article_number":"165426","language":[{"iso":"eng"}],"citation":{"ieee":"F.

The Ga droplets can be crystallized into GaAs quantum dots using a crystallization step under As flux. In order to model the complex process, including the masked deposition of the droplets and a reduction of their number during a thermal annealing step, a multiscale kinetic Monte Carlo (mkMC) simulation of self-assembled Ga droplet formation on AlGaAs is expanded for area-selective deposition. The simulation has only two free model parameters: the activation energy for surface diffusion and the activation energy for thermal escape of adatoms from a droplet. Simulated droplet numbers within the opening of the aperture agree quantitatively with the experimental results down to the perfect site-control, with one droplet per aperture. However, the model parameters are different compared to those of the self-assembled droplet growth. We attribute this to the presence of the mask in close proximity to the surface, which modifies the local process temperature and the As background. This approach also explains the dependence of the model parameters on the size of the aperture.</jats:p>"}],"publication":"Nanomaterials","issue":"3","doi":"10.3390/nano13030466","article_number":"466","language":[{"iso":"eng"}],"date_updated":"2023-08-03T11:14:10Z","publication_status":"published","intvolume":"        13","title":"Modeling of Masked Droplet Deposition for Site-Controlled Ga Droplets","year":"2023","author":[{"last_name":"Feddersen","first_name":"Stefan","full_name":"Feddersen, Stefan"},{"full_name":"Zolatanosha, Viktoryia","last_name":"Zolatanosha","first_name":"Viktoryia"},{"last_name":"Alshaikh","first_name":"Ahmed","full_name":"Alshaikh, Ahmed"},{"id":"37763","full_name":"Reuter, Dirk","last_name":"Reuter","first_name":"Dirk"},{"full_name":"Heyn, Christian","last_name":"Heyn","first_name":"Christian"}],"publication_identifier":{"issn":["2079-4991"]}},{"abstract":[{"text":"We present a miniaturized pulse shaping device that creates an arbitrary dispersion through the interaction of multiple metasurfaces on less than 2 mm<jats:sup>3</jats:sup> volume.

In this work, we find that in a liquid crystal (LC) microcavity\nfilled with perovskite microplates, the pronounced TE-TM splitting gives rise\nto a strong SOC that leads to the spatial instability of microcavity polariton\ncondensates under single-shot excitation. Spatially varying hole burning and\nmode competition occurs between polarization components leading to different\ncondensate profiles from shot to shot. The single-shot polariton condensates\nbecome stable when the SOC vanishes as the TE and TM modes are spectrally well\nseparated from each other, which can be achieved by application of an electric\nfield to our LC microcavity with electrically tunable anisotropy. Our findings\nare well reproduced and traced back to their physical origin by our detailed\nnumerical simulations.

For circularly polarised light, the same meta-lens can act as a converging or diverging lens, depending on the handedness of the circular polarisation. This effect enables application for optical tweezers that trap or release µm-size polymer beads floating in a microfluidic channel on demand. An electrically addressable polarisation converter based on liquid crystals may be used to switch between the two states of polarisation, at which the light transmitted through the meta-lens is focused (trapping) or defocussed (releasing), respectively.","lang":"eng"}],"issue":"7-10","publication":"Liquid Crystals","department":[{"_id":"313"},{"_id":"230"},{"_id":"638"},{"_id":"15"},{"_id":"623"}],"type":"journal_article","date_created":"2023-01-27T12:42:16Z"},{"publication":"Physical Review Research","issue":"4","date_created":"2024-08-30T04:48:05Z","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"293"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"623"},{"_id":"27"}],"type":"journal_article","publication_identifier":{"issn":["2643-1564"]},"author":[{"id":"55907","first_name":"Dennis","orcid":"0009-0007-5654-5412","last_name":"Scharwald","full_name":"Scharwald, Dennis"},{"id":"344","full_name":"Meier, Torsten","orcid":"0000-0001-8864-2072","first_name":"Torsten","last_name":"Meier"},{"full_name":"Sharapova, Polina","first_name":"Polina","last_name":"Sharapova"}],"year":"2023","title":"Phase sensitivity of spatially broadband high-gain SU(1,1) interferometers","intvolume":"         5","publication_status":"published","date_updated":"2026-02-01T13:21:22Z","language":[{"iso":"eng"}],"article_number":"043158","main_file_link":[{"open_access":"1","url":"https://journals.aps.org/prresearch/pdf/10.1103/PhysRevResearch.5.043158"}],"doi":"10.1103/physrevresearch.5.043158","citation":{"mla":"Scharwald, Dennis, et al. “Phase Sensitivity of Spatially Broadband High-Gain SU(1,1) Interferometers.” <i>Physical Review Research</i>, vol. 5, no. 4, 043158, American Physical Society (APS), 2023, doi:<a href=\"https://doi.org/10.1103/physrevresearch.5.043158\">10.1103/physrevresearch.5.043158</a>.","apa":"Scharwald, D., Meier, T., &#38; Sharapova, P.
