Profile Summary

Werner H. E. Hofmann received his Dipl-Ing (M.S.) degree in electrical engineering and information technology in 2003 and the Dr.-Ing. (Ph.D.) degree in 2009, both from the Technical University of Munich, Germany.
From 2003 to 2008, he was with the the group of Prof. Amann at the Walter Schottky Institute, where he was engaged in research on long-wavelength vertical-cavity surface-emitting lasers (VCSELs). Subsequently, he joined Prof. Chang-Hasnain´s Group, University of California, Berkeley (UCB), where he worked on the incorporation of high-contrast gratings into VCSEL devices. In 2010, he joined the Technical University of Berlin (TU Berlin), Germany, as principal scientist in the group of Prof. Bimberg. Since 2013 Prof. Hofmann is leading his own group focusing on ultra-high-speed nanophotonic devices. Prof. Hofmann is also the Chief Technical Officer at the Centre of Nanophotonics at TU Berlin. Since 2014 he is also with the Xiamen University, P. R. China as guest professor and highly qualified foreign expert.
He received the E.ON Future Award in 2009 and the SPIE Green Photonics Award in 2012 for his research on high-speed, energy efficient VCSELs. Prof. Hofmann authored over 100 papers cited over 500 times and has presented over 10 invited talks and tutorials on international conferences. He is a member of the Association of the German Engineers (VDI), the German Association of University Professors (DHV) and the IEEE Photonics Society. His main research interests are high-speed surface emitters and their advance by nano-photonics.
