[{"publication":"Optics Letters","abstract":[{"lang":"eng","text":"Here we demonstrate a new, to the best of our knowledge, type of 3-dB coupler that has an ultra-broadband operational range from 1300 to 1600 nm with low fabrication sensitivity. The overall device size is 800 µm including in/out S-bend waveguides. The coupler is an asymmetric non-uniform directional coupler that consists of two tapered waveguides. One of the coupler arms is shifted by 100 µm in the propagation direction, which results in a more wavelength-insensitive 3-dB response compared to a standard (not shifted) coupler. Moreover, compared to a long adiabatic coupler, we achieved a similar wavelength response at a 16-times-smaller device length. The couplers were fabricated using the silicon nitride platform of Lionix International. We also experimentally demonstrated an optical switch that is made by using two of these couplers in a Mach–Zehnder interferometer configuration. According to experimental results, this optical switch exhibits –10 dB of extinction ratio over the 1500–1600 nm wavelength range. Our results indicate that this new type of coupler holds great promise for various applications, including optical imaging, telecommunications, and reconfigurable photonic processors where compact, fabrication-tolerant, and wavelength-insensitive couplers are essential."}],"file":[{"embargo_to":"open_access","content_type":"application/pdf","relation":"main_file","date_updated":"2023-01-03T09:36:34Z","creator":"fossie","date_created":"2023-01-03T09:36:34Z","file_size":3731864,"file_id":"35129","access_level":"local","file_name":"2023-01 Nikbakht - Optics Letter - Asymmetric, non-uniform 3-dB directional coupler with 300-nm bandwidth and small footprint.pdf","embargo":"2024-01-03"}],"ddc":["530"],"keyword":["tet_topic_waveguide"],"language":[{"iso":"eng"}],"issue":"2","year":"2022","publisher":"Optica Publishing Group","date_created":"2023-01-03T09:32:47Z","title":"Asymmetric, non-uniform 3-dB directional coupler with 300-nm bandwidth and a small footprint","type":"journal_article","status":"public","_id":"35128","user_id":"158","department":[{"_id":"61"},{"_id":"230"}],"file_date_updated":"2023-01-03T09:36:34Z","publication_status":"published","has_accepted_license":"1","publication_identifier":{"issn":["0146-9592","1539-4794"]},"citation":{"mla":"Nikbakht, Hamed, et al. “Asymmetric, Non-Uniform 3-DB Directional Coupler with 300-Nm Bandwidth and a Small Footprint.” <i>Optics Letters</i>, vol. 48, no. 2, Optica Publishing Group, 2022, p. 207, doi:<a href=\"https://doi.org/10.1364/ol.476537\">10.1364/ol.476537</a>.","short":"H.

We consider spherical clusters, thick layers and monolayers with realistic topologies and dimensions much larger than the wavelength of light. The maximum bulk packing density of clusters is 0.5. A numerically exact solution of the electromagnetic problem is obtained using the Discontinuous Galerkin Time Domain method and with application of high- performance computing. We show that high packing density causes light localization in such structures which makes an impact on the opposition phenomena: backscattering intensity surge and negative linear polarization feature. Diffuse multiple scattering is significantly reduced in the case of non-absorbing particles and near-field interaction results in a percolation-like light transport determined by the topology of the medium. With this the negative polarization feature caused by single scattering gets enhanced if compared to lower density samples. We also confirm coherent double scattering mechanism of negative polarization for light scattered from dense absorbing slabs. In this case convergent result for the scattering angle polarization dependency at backscattering can be obtained for a layer of just a few tens of particles if they are larger than the wavelength."}],"file":[{"creator":"fossie","date_created":"2022-09-22T09:24:45Z","date_updated":"2022-09-22T09:24:45Z","file_name":"2022-09 Grynko - Book chapter on Light Scattering by Large Densely Packed Clusters of Particles.pdf","file_id":"33467","access_level":"local","file_size":1525307,"content_type":"application/pdf","relation":"main_file"}],"keyword":["tet_topic_scattering"],"ddc":["530"],"language":[{"iso":"eng"}]},{"title":"Assessment of Energy Efficiency and Flexibility Measures in Electrified Process Heat Generation Based on Simulations in the Animal Feed Industry","author":[{"first_name":"Lukas","last_name":"Knorr","full_name":"Knorr, Lukas","id":"90391"},{"last_name":"Schlosser","id":"88614","full_name":"Schlosser, Florian","first_name":"Florian"},{"first_name":"Henning","orcid":"0000-0002-1538-089X","last_name":"Meschede","full_name":"Meschede, Henning","id":"86954"}],"date_created":"2023-01-11T12:49:28Z","date_updated":"2023-10-02T09:02:05Z","publisher":"17th sdewes conference","citation":{"ieee":"L.

CHBs can be interpreted as modular multilevel converters with an isolated DC-DC output stage per module, require a large DC-link capacitor for each module to handle the second harmonic voltage ripple caused by the fluctuating input power within a fundamental grid period. Without a zero-sequence voltage injection, star-connected CHBs are operated with approximately sinusoidal arm voltages and currents. The floating star point potential enables to utilize different zero-sequence voltage injection techniques such as a third-harmonic injection with 1/6 of the grid voltage amplitude or a Min-Max voltage injection. Both well-known methods have the advantage to reduce the peak arm voltage and thereby the number of required modules by 13.4 % (to √ 3 2). This paper proves analytically that the third-harmonic injection with 1/6 of the grid voltage amplitude reduces the second harmonic voltage ripple by only 15.1 % compared to no-voltage injection for unity power factor operation and balanced grid voltages. Then it is shown, that the Min-Max injection has the often overlooked advantage of reducing the second harmonic voltage ripple by even 18.8 %. By applying the here proposed zero-sequence voltage injection in saturation modulation, the second harmonic voltage ripple of the DC-link capacitors is reduced by even 24.3 %, while still requiring the same number of modules as the Min-Max injection. For a realistic number of reserve modules, the overall energy ripple in the DC-link capacitors is reduced by 40 %.","lang":"eng"}],"status":"public","type":"conference","publication":"24th European Conference on Power Electronics and Applications (EPE'22 ECCE Europe)","keyword":["Cascaded H-Bridge","Solid-State Transformer","Zero sequence voltage","Third harmonic injection","Capacitor voltage ripple"],"language":[{"iso":"eng"}],"_id":"34176","user_id":"34289","department":[{"_id":"52"}],"year":"2022","citation":{"ama":"Unruh R, Schafmeister F, Böcker J.

Additionally, a simulation framework for SSB signals is introduced and utilized for training the NNs. The CFO estimator is combined with a speech enhancement network to investigate its influence on the enhancement performance. The NN-based system is compared to a recently proposed pitch tracking based approach on publicly available data from real high frequency transmissions. Experiments show that the NN exhibits good CFO estimation properties and results in significant improvements in speech intelligibility, especially when combined with a noise reduction network.","lang":"eng"}]},{"language":[{"iso":"eng"}],"_id":"33806","department":[{"_id":"54"}],"user_id":"460","status":"public","publication":"2022 International Wireless Communications and Mobile Computing (IWCMC)","type":"conference","title":"Data-driven Time Synchronization in Wireless Multimedia Networks","doi":"10.1109/iwcmc55113.2022.9824980","publisher":"IEEE","date_updated":"2023-10-26T08:16:07Z","date_created":"2022-10-18T09:24:17Z","author":[{"last_name":"Afifi","full_name":"Afifi, Haitham","first_name":"Haitham"},{"full_name":"Karl, Holger","last_name":"Karl","first_name":"Holger"},{"first_name":"Tobias","full_name":"Gburrek, Tobias","id":"44006","last_name":"Gburrek"},{"first_name":"Joerg","last_name":"Schmalenstroeer","id":"460","full_name":"Schmalenstroeer, Joerg"}],"year":"2022","citation":{"ama":"Afifi H, Karl H, Gburrek T, Schmalenstroeer J.

Training and evaluation of these single tasks requires synthetic\r\ndata with access to intermediate signals that is as close as possible to the\r\nevaluation scenario. As such data often is not available, many works instead\r\nuse specialized databases for the training of each system component, e.g\r\nWSJ0-mix for source separation. We present a Multi-purpose Multi-Speaker\r\nMixture Signal Generator (MMS-MSG) for generating a variety of speech mixture\r\nsignals based on any speech corpus, ranging from classical anechoic mixtures\r\n(e.g., WSJ0-mix) over reverberant mixtures (e.g., SMS-WSJ) to meeting-style\r\ndata. Its highly modular and flexible structure allows for the simulation of\r\ndiverse environments and dynamic mixing, while simultaneously enabling an easy\r\nextension and modification to generate new scenarios and mixture types. These\r\nmeetings can be used for prototyping, evaluation, or training purposes. We\r\nprovide example evaluation data and baseline results for meetings based on the\r\nWSJ corpus. Further, we demonstrate the usefulness for realistic scenarios by\r\nusing MMS-MSG to provide training data for the LibriCSS database.","lang":"eng"}],"publication":"2022 International Workshop on Acoustic Signal Enhancement (IWAENC)","language":[{"iso":"eng"}],"ddc":["000"],"external_id":{"arxiv":["2209.11494"]}},{"type":"conference","status":"public","_id":"33807","department":[{"_id":"54"}],"user_id":"44006","file_date_updated":"2023-11-17T06:39:04Z","has_accepted_license":"1","publication_status":"published","citation":{"ieee":"T.

Such labels are required when training a neural network for object recognition from radar data. The automatic labeling approach rests on the simultaneous recording of camera and lidar data in addition to the radar spectrum. By warping radar spectra into the camera image, state-of-the-art object recognition algorithms can be applied to label relevant objects, such as cars, in the camera image. The warping operation is designed to be fully differentiable, which allows backpropagating the gradient computed on the camera image through the warping operation to the neural network operating on the radar data. As the warping operation relies on accurate scene flow estimation, we further propose a novel scene flow estimation algorithm which exploits information from camera, lidar and radar sensors. The\r\nproposed scene flow estimation approach is compared against a state-of-the-art scene flow algorithm, and it outperforms it by approximately 30% w.r.t. mean average error. The feasibility of the overall framework for automatic label generation for\r\nRD spectra is verified by evaluating the performance of neural networks trained with the proposed framework for Direction-of-Arrival estimation.","lang":"eng"}],"file":[{"content_type":"application/pdf","relation":"main_file","creator":"huesera","date_created":"2022-09-22T07:00:29Z","date_updated":"2022-09-22T07:00:29Z","file_name":"T-VT_AcceptedVersion.pdf","access_level":"open_access","file_id":"33460","file_size":12117870}],"date_updated":"2023-11-20T16:37:16Z","oa":"1","author":[{"first_name":"Christopher","full_name":"Grimm, Christopher","last_name":"Grimm"},{"first_name":"Tai","last_name":"Fei","full_name":"Fei, Tai"},{"first_name":"Ernst","last_name":"Warsitz","full_name":"Warsitz, Ernst"},{"first_name":"Ridha","last_name":"Farhoud","full_name":"Farhoud, Ridha"},{"full_name":"Breddermann, Tobias","last_name":"Breddermann","first_name":"Tobias"},{"first_name":"Reinhold","last_name":"Haeb-Umbach","id":"242","full_name":"Haeb-Umbach, Reinhold"}],"volume":71,"doi":"10.1109/TVT.2022.3182411","has_accepted_license":"1","citation":{"chicago":"Grimm, Christopher, Tai Fei, Ernst Warsitz, Ridha Farhoud, Tobias Breddermann, and Reinhold Haeb-Umbach. “Warping of Radar Data Into Camera Image for Cross-Modal Supervision in Automotive Applications.” <i>IEEE Transactions on Vehicular Technology</i> 71, no. 9 (2022): 9435–49. <a href=\"https://doi.org/10.1109/TVT.2022.3182411\">https://doi.org/10.1109/TVT.2022.3182411</a>.","ieee":"C.
