Volker Harle

Volker Härle received the M.S. degree in physics from University of Massachusetts, in 1988, and the diploma degree in physics and Ph.D degree from the University of Stuttgart, Stuttgart, Germany, in 1990 and 1994, respectively. His dissertation was on the physics of strained GaInAs–InP-structures resulting in optical modulators, amplifiers and lasers using low-pressure MOVPE as growth method. He joined France Telecom, Paris/Bagneux, France, in 1991. In 1994, he started with the MOVPE growth of GaInN-structures and GaInN-devices as a Postdoctoral Researcher at Stuttgart University and joined Siemens in 1996 as a Process Engineer for GaInN-MOVPE growth. In 1997, he took over the responsibility of all MOVPE research and development including AlGaInP and GaInN at Siemens and in 1999, he became Head of GaInN-R&D. Today he is heading all nitride R&D at OSRAM-OS including MOVPE production as a Senior Director of R&D. Major achievements where the development of ATON- and ThinGaN-Technology, as well as the first European CW blue laser.
