Johann Peter Reithmaier studied Physics at TU Munich and made his PhD at Siemens Research Labs and Walter-Schottky-Institute in 1990. Until 1992, he worked as Postdoc at IBM in Rüschlikon, Switzerland on III/V epitaxy for high power and telecom lasers. In 1992, he joined University of Würzburg where he built up a research group working on nanostructured semiconductors and their applications in optoelectronic devices. He finished Habilitation in 1997 and became a faculty member of physics in Würzburg. In 2005 he became a full professor of physics and director of the Institute of Nanostructure Technologies and Analytics (INA) at the University of Kassel.

He is author or co-author of more than 800 publications (about 375 in peer reviewed journals, 10 book articles, 2 books, 8 patent applications, more than 150 invited talks, more than 15000 citations, hindex = 52 (Google Scholar)). He was coordinator of several European projects and contributed to many national and international projects covering a wide range of research topics from material research to semiconductor devices, e.g., single photon sources, high power lasers and high-speed telecom lasers. He is a member of the Deutsche Physikalische Gesellschaft (DPG) and Fellow of IEEE. From 2014 to 2020, he was co-editor of OPTICA. He is/was a member of the advisory board of different national centers (from 2010 to 2016: National Centre of III-V Materials in UK, since 2016: Centre of Nanophotonics for Terabit Communications (NATEC) in Denmark) and since 2021: Technical Advisory Board of EPSRC research consortium "QUantum Dot On Silicon systems for communications, information processing and sensing" (QUDOS), UK). Since 2016, he is speaker of the Center of Interdisciplinary Nanostructure Science and Technology (CINSaT) of the University of Kassel and Coordinator of the LOEWE priority project SMolBits (Scalable Molecular Quantum Bits).

He has more than 35 years of experience in laser physics and optoelectronic devices, more than 30 years in molecular beam epitaxy and more than 25 years in nanostructuring of semiconductor materials. His research group participated in 13 European projects (three of them coordinated by him) and more than 17 national projects (BMBF, DFG, VW foundation, LOEWE). He is reviewer for numereous journals (PRL, PRB, APL, JAP, IEEE journals, OSA journals, ...) and for national (BMBF, DFG) and international funding agencies (EU, ISF, GIF, SRC, EPSRC, SNF, FWF, NSERC, DOE, ...).

The main interest is focused on III-V nanostructured materials and optoelectronic or nanophotonic devices dedicated for applications in classical and quantum optical communication systems. This includes material research for new epitaxial materials (e.g. III-V nanostructures on GaAs, InP and Si substrates as well as nano crystalline diamond), development of new nano fabrication technologies and novel optoelectronic devices (e.g., high-speed quantum dot lasers, single photon emitters, all-optical nano photonic devices, quantum memories based on diamond related color centers, etc.) as well as new quantum optics and quantum communication platforms (e.g., hybrid quantum systems based on molecular QuBits on semiconductor nanophotonic chips or quantum dot based optoelectronics integrated on Si photonic/microelectronic platforms).

Some important achievements:

• Realization of photonic counterparts of atoms, molecules and chains based on high-Q cavities
  
• First realization and proof of strong-coupling on a single particle level (Exciton-Photon Polariton)
  
• Realization of QD gain materials for high power application (920, 980, 1060 nm) with record values in laser performance
  
• Realization of InP-based 1.55 µm single photon emitters and nanophotonic elements for quantum communication
  
• Realization of high performance InP-based QD materials and devices for telecom applications (1.55 µm) with record values in temperature stability, modulation speed and emission linewidth
