Biography
Johannes Koeth was born in 1968 in Kassel, Germany. He graduated 1996 in Physics at the University of Würzburg with studies on molecular beam epitaxy (MBE) and optical properties of GaN. During his Ph.D. he worked on MBE of lasers in the AlGaSb system in the wavelength range between 1.5 µm and 2.0 µm. One of the main topics of his thesis was the investigation of GaSb based emitters on GaAs substrates. He realized e.g. the first GaSb edge emitting laser diodes based on GaAs as well as optically pumped Ga(Al)Sb/AlSb VCSELs, both at 1.5 µm. In addition, he developed and characterized antimonide based DFB lasers in the 2 µm range. In 1998 he founded nanoplus Nanosystems and Technologies GmbH and has presided the company as CEO since then.
