Nano-ridge engineering is a new approach that enables the integration of III–V based devices on trench-patterned Si substrates with very high crystal quality. Using selective area growth, the III–V material is deposited into narrow trenches to reduce the dislocation defect density by aspect ratio trapping. The growth is continued out of the trench pattern and a box-shaped III–V nano-ridge is engineered by adjusting the growth parameters. A flat (001) GaAs nano-ridge surface enables the epitaxial integration of a common InGaAs/GaAs multi-quantum-well (MQW) structure as an optical gain medium to build a laser diode. In this study, a clear correlation is found between the photoluminescence (PL) lifetime, extracted from time-resolved photoluminescence (TRPL) measurements, with the InGaAs/GaAs nano-ridge size and defect density, which are both predefined by the nano-ridge related pattern trench width. Through the addition of an InGaP passivation layer, a MQW PL lifetime of up to 800 ps and 1000 ps is measured when pumped at 900 nm (only QWs were excited) and 800 nm (QWs + barrier excited), respectively. The addition of a bottom carrier blocking layer further increases this lifetime to ∼2.5ns (pumped at 800 nm), which clearly demonstrates the high crystal quality of the nano-ridge material. These TRPL measurements not only deliver quick and valuable feedback about the III–V material quality but also provide an important understanding for the heterostructure design and carrier confinement of the nano-ridge laser diode.","lang":"eng"}],"publication":"Journal of Applied Physics","issue":"10","department":[{"_id":"977"}],"type":"journal_article","date_created":"2025-04-25T07:18:24Z","intvolume":"       127","publication_status":"published","date_updated":"2025-04-25T07:28:42Z","author":[{"last_name":"Shi","first_name":"Yuting","full_name":"Shi, Yuting"},{"full_name":"Kreuzer, Lisa C.","last_name":"Kreuzer","first_name":"Lisa C."},{"orcid":"0009-0002-5538-231X","last_name":"Gerhardt","first_name":"Nils Christopher","full_name":"Gerhardt, Nils Christopher","id":"115298"},{"first_name":"Marianna","last_name":"Pantouvaki","full_name":"Pantouvaki, Marianna"},{"last_name":"Van Campenhout","first_name":"Joris","full_name":"Van Campenhout, Joris"},{"full_name":"Baryshnikova, Marina","last_name":"Baryshnikova","first_name":"Marina"},{"full_name":"Langer, Robert","last_name":"Langer","first_name":"Robert"},{"full_name":"Van Thourhout, Dries","first_name":"Dries","last_name":"Van Thourhout"},{"first_name":"Bernardette","last_name":"Kunert","full_name":"Kunert, Bernardette"}],"publication_identifier":{"issn":["0021-8979","1089-7550"]},"title":"Time-resolved photoluminescence characterization of InGaAs/GaAs nano-ridges monolithically grown on 300 mm Si substrates","year":"2020","doi":"10.1063/1.5139636","language":[{"iso":"eng"}]},{"status":"public","_id":"59685","publisher":"Elsevier BV","volume":"316-317","user_id":"15911","citation":{"chicago":"Žutić, Igor, Gaofeng Xu, Markus Lindemann, Paulo E.

Through carrier recombination, the angular momentum of the spin-polarized carriers is transferred to photons, thus leading to the circularly polarized emitted light. The intuition for the operation of such spin-lasers can be obtained from simple bucket and harmonic oscillator models, elucidating their steady-state and dynamic response, respectively. These lasers extend the functionalities of spintronic devices and exceed the performance of conventional (spin-unpolarized) lasers, including an order of magnitude faster modulation frequency. Surprisingly, this ultrafast operation relies on a short carrier spin relaxation time and a large anisotropy of the refractive index, both viewed as detrimental in spintronics and conventional lasers. Spin-lasers provide a platform to test novel concepts in spin devices and offer progress connected to the advances in more traditional areas of spintronics."}],"date_created":"2025-04-25T07:11:46Z","department":[{"_id":"977"}],"type":"journal_article"},{"status":"public","publisher":"Optica Publishing Group","_id":"59684","user_id":"15911","volume":60,"citation":{"chicago":"Schnitzler, Lena, Krisztian Neutsch, Falk Schellenberg, Martin R.

Exact results can only be achieved when a single specimen is used in the identification process, which typically is prone to the problem of low sensitivities to certain material parameters and thus high uncertainties. Therefore, a custom electrode topology for increased sensitivity is proposed for a piezoceramic disc. The thereupon conducted measurements of the electric impedance can be used as a starting point for an inverse approach where an equivalent simulation model is used to identify fitting material parameters. An optimisation strategy based on a preliminary sensitivity analysis is presented that leads to a good agreement between measurement and simulation. Furthermore, the proposed measurement procedure is able to evaluate the quality of the simulation model. Hence, different frequency-dependent damping models are presented and evaluated.","lang":"eng"}],"date_created":"2020-09-11T11:57:50Z","department":[{"_id":"49"}],"type":"journal_article"},{"department":[{"_id":"54"}],"type":"conference","date_created":"2020-12-11T12:28:49Z","file":[{"creator":"cbj","date_created":"2020-12-11T12:32:44Z","date_updated":"2020-12-11T12:32:44Z","relation":"main_file","file_size":200127,"access_level":"open_access","file_name":"convBF.pdf","content_type":"application/pdf","file_id":"20698"}],"publication":"ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)","doi":"10.1109/icassp40776.2020.9054393","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2024-11-14T09:17:32Z","author":[{"first_name":"Christoph","last_name":"Boeddeker","full_name":"Boeddeker, Christoph","id":"40767"},{"last_name":"Nakatani","first_name":"Tomohiro","full_name":"Nakatani, Tomohiro"},{"full_name":"Kinoshita, Keisuke","first_name":"Keisuke","last_name":"Kinoshita"},{"full_name":"Haeb-Umbach, Reinhold","first_name":"Reinhold","last_name":"Haeb-Umbach","id":"242"}],"publication_identifier":{"isbn":["9781509066315"]},"year":"2020","title":"Jointly Optimal Dereverberation and Beamforming","oa":"1","project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"citation":{"mla":"Boeddeker, Christoph, et al. “Jointly Optimal Dereverberation and Beamforming.” <i>ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)</i>, 2020, doi:<a href=\"https://doi.org/10.1109/icassp40776.2020.9054393\">10.1109/icassp40776.2020.9054393</a>.","bibtex":"@inproceedings{Boeddeker_Nakatani_Kinoshita_Haeb-Umbach_2020, title={Jointly Optimal Dereverberation and Beamforming}, DOI={<a href=\"https://doi.org/10.1109/icassp40776.2020.9054393\">10.1109/icassp40776.2020.9054393</a>}, booktitle={ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)}, author={Boeddeker, Christoph and Nakatani, Tomohiro and Kinoshita, Keisuke and Haeb-Umbach, Reinhold}, year={2020} }","ama":"Boeddeker C, Nakatani T, Kinoshita K, Haeb-Umbach R.

In the proposed concept, a modular multi-level converter (MMC) is used to step-down the three-phase medium voltage of 10 kV, and provide up to 1 MW of pure DC power to the load consisting of electrolyzers for hydrogen generation. Therefore, each module is extended by an LLC resonant converter to adapt to the specific electrolyzers DC voltage range of 142...220 V and to provide galvanic isolation. In order to achieve a high efficiency for a wide range of load conditions, the input voltage of the LLC converter is adjusted between 600 V and 770 V while operating at resonance or close to resonance. The parameters of the 11kW LLC resonant converter with an integrated leakage inductance are systematically optimized to maximize the efficiency for all loads while achieving zero-voltage switching. For a fast estimation of eddy current losses, a new method is proposed, which uses a single FEM simulation to fit newly developed loss equations. The calculated average efficiency is 97.8%. The prototype of the LLC converter reaches a peak efficiency of over 98% at resonance at half load which is similar to the precalculated value.","lang":"eng"}],"publication":"2020 IEEE 21st Workshop on Control and Modeling for Power Electronics (COMPEL)","department":[{"_id":"52"}],"type":"conference","keyword":["Full-bridge","High voltage power converters","LLC resonant converter","Multilevel converters","ZVS Converters"],"date_created":"2022-02-18T16:29:08Z"},{"department":[{"_id":"61"},{"_id":"230"},{"_id":"429"},{"_id":"51"}],"type":"conference_abstract","date_created":"2023-01-25T11:11:42Z","place":"Munich/Germany","citation":{"mla":"Förstner, Jens, et al. “Ultrafast Electric Control of a Single QD Exciton.” <i>11th International Conference on Quantum Dots</i>, 2020.","apa":"Förstner, J., Widhalm, A., Mukherjee, A., Krehs, S., Jonas, B., Spychala, K., Förstner, J., Thiede, A., Reuter, D., &#38; Zrenner, A.
