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."}]},{"year":"2020","title":"Spin-lasers: spintronics beyond magnetoresistance","author":[{"full_name":"Žutić, Igor","last_name":"Žutić","first_name":"Igor"},{"last_name":"Xu","first_name":"Gaofeng","full_name":"Xu, Gaofeng"},{"last_name":"Lindemann","first_name":"Markus","full_name":"Lindemann, Markus"},{"first_name":"Paulo E.","last_name":"Faria Junior","full_name":"Faria Junior, Paulo E."},{"first_name":"Jeongsu","last_name":"Lee","full_name":"Lee, Jeongsu"},{"full_name":"Labinac, Velimir","last_name":"Labinac","first_name":"Velimir"},{"full_name":"Stojšić, Kristian","first_name":"Kristian","last_name":"Stojšić"},{"first_name":"Guilherme M.","last_name":"Sipahi","full_name":"Sipahi, Guilherme M."},{"full_name":"Hofmann, Martin R.","first_name":"Martin R.","last_name":"Hofmann"},{"id":"115298","full_name":"Gerhardt, Nils Christopher","orcid":"0009-0002-5538-231X","last_name":"Gerhardt","first_name":"Nils Christopher"}],"publication_identifier":{"issn":["0038-1098"]},"publication_status":"published","date_updated":"2025-04-25T07:28:46Z","article_type":"review","article_number":"113949","language":[{"iso":"eng"}],"doi":"10.1016/j.ssc.2020.113949","publication":"Solid State Communications","abstract":[{"text":"Introducing spin-polarized carriers in semiconductor lasers reveals an alternative path to realize room-temperature spintronic applications, beyond the usual magnetoresistive effects. 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.","lang":"eng"}],"date_created":"2025-04-25T07:11:46Z","type":"journal_article","department":[{"_id":"977"}],"status":"public","_id":"59685","publisher":"Elsevier BV","user_id":"15911","volume":"316-317","citation":{"ieee":"I.

The introduction of novel concepts in laser operation thus has potential to lead to both new applications and fundamental insights2. Spintronics3, in which both the spin and the charge of the electron are used, has led to the development of spin-lasers, in which charge-carrier spin and photon spin are exploited. Here we show experimentally that the coupling between carrier spin and light polarization in common semiconductor lasers can enable room-temperature modulation frequencies above 200 gigahertz, exceeding by nearly an order of magnitude the best conventional semiconductor lasers. Surprisingly, this ultrafast operation of the resultant spin-laser relies on a short carrier spin relaxation time and a large anisotropy of the refractive index, both of which are commonly viewed as detrimental in spintronics3 and conventional lasers4. Our results overcome the key speed limitations of conventional directly modulated lasers and offer a prospect for the next generation of low-energy ultrafast optical communication."}],"extern":"1"},{"_id":"64371","language":[{"iso":"eng"}],"user_id":"15911","doi":"10.1117/12.2292032","author":[{"full_name":"Hofmann, Martin R.","last_name":"Hofmann","first_name":"Martin R."},{"full_name":"Lenz, Marcel","last_name":"Lenz","first_name":"Marcel"},{"first_name":"Robin","last_name":"Krug","full_name":"Krug, Robin"},{"id":"115298","full_name":"Gerhardt, Nils Christopher","last_name":"Gerhardt","first_name":"Nils Christopher","orcid":"0009-0002-5538-231X"},{"full_name":"Schmieder, Kirsten","first_name":"Kirsten","last_name":"Schmieder"},{"first_name":"Christopher","last_name":"Dillmann","full_name":"Dillmann, Christopher"},{"first_name":"Hubert","last_name":"Welp","full_name":"Welp, Hubert"}],"title":"Brain tissue analysis using texture features based on optical coherence tomography images","year":"2018","status":"public","date_updated":"2026-02-25T13:45:03Z","date_created":"2026-02-20T10:04:04Z","department":[{"_id":"977"}],"type":"conference","citation":{"bibtex":"@inproceedings{Hofmann_Lenz_Krug_Gerhardt_Schmieder_Dillmann_Welp_2018, title={Brain tissue analysis using texture features based on optical coherence tomography images}, DOI={<a href=\"https://doi.org/10.1117/12.2292032\">10.1117/12.2292032</a>}, booktitle={Optical Coherence Tomography and Coherence Domain Optical Methods in Biomedicine XXII}, author={Hofmann, Martin R. and Lenz, Marcel and Krug, Robin and Gerhardt, Nils Christopher and Schmieder, Kirsten and Dillmann, Christopher and Welp, Hubert}, year={2018} }","ama":"Hofmann MR, Lenz M, Krug R, et al.
