Speaker：Chung-en Zah（Research Director, Semiconductor Technologies Research）
Time： 9:30 am, June 23 (Thursday), 2011
Venue：Transient Building, third floor conference room
Corning semiconductor Technologies Research core competency and key projects over the last 12 years will be briefly reviewed. Recent progresses on mid-IR quantum cascade lasers and true green InGaN lasers will be presented.
Chung-en Zah received the M. S. and the Ph. D. degrees from California Institute of Technology, Pasadena, CA, USA, in 1982 and 1986, respectively. He joined Bell Communications Research (Bellcore), Red Bank, NJ, as a member of the Technical Staff in 1985 and was promoted to Senior Scientist in January 1995 and to Director of Optoelectronic Integration Research in April 1995. He joined the Science and Technology Division of Corning Incorporated on August 1, 1997, when Corning acquired his group from Bellcore, and is currently Research Director of Semiconductor Technologies Research. His department has participated in commercializing state of the art high power 980 and 14xx nm pumps. The recent research and development includes high power 1060-nm DBR lasers for green light generation by frequency doubling, visible GaN lasers, mid-IR quantum cascade lasers and 1.3/1.55 mm vertical cavity surface emitting lasers. He has authored or co-authored more than one hundred and fifteen (seven invited) journal papers and one hundred and seventy (thirty-one invited) conference papers, and holds twenty-eight U. S. Patents in the areas of optoelectronic devices and optical fiber communications.
Dr. Zah received the Bellcore Distinguished Member of Technical Staff Award in 1992 for his innovative contributions to the applications of lightwave technology to advanced fiber networks, an R&D 100 award in 1994 and LEOS Engineering Achievement Award in 2005 for his uncooled AlGaInAs lasers designed for fiber-in-the-loop applications, and another R&D 100 award in 1996 for WDM network access modules incorporating his multiwavelength DFB laser arrays. He is a fellow of the Institute of Electrical and Electronics Engineers and the Optical Society of America. He has served on numerous technical committees for APOC, CLEO, ECOC, IEDM, IPR, ISLC, LEOS, and OFC, as a conference chair of LEOS’2003 and APOC’2007, and as an Associate Editor of Photonics Technology Letters from 1993 to 2008 and and Journal of Lightwave Technology since 2009.
