Dubravko Babić was born in Zagreb, Croatia. He received his Dipl. Ing. Degree from University of Zagreb, Faculty of Electrical Engineering and Computing, in 1982, and his M. Sc. and Ph. D. in Electrical and Computer Engineering at University of California, Santa Barbara in 1984 and 1995, respectively.
Between 1982 and 1985 he worked as a graduate student on the measurement of AlGaAs/GaAs heterojunction band-offsets by capacitance-voltage profiling with prof. Herbert Kroemer at UC Santa Barbara. From 1985 to 1989 he worked at Avantek, Inc. (Santa Clara, California) as a Design Engineer, on the development of microwave and millimeter-wave diodes.
In 1989, he joined the Ultrafast Optoelectronics Group at UC Santa Barbara, as a graduate student to work on the development of vertical-cavity surface-emitting lasers (VCSELs) where in 1995 he demonstrated the world’s first room-temperature continuous-wave operating long-wavelength (1550 nm) VCSEL. From 1995 to 1999, he was a Member of Technical Staff at Hewlett-Packard Laboratories (Palo Alto, California) working on VCSEL development using wafer bonding technology.
In 1999, he founded Alvésta Corporation, manufacturer of 10Gb/s multichannel fiber-optic modules, where he served as the company's first Chief Executive Officer and then in 2001 as Chief Technical Officer. Between 2003 and 2008, he assisted Clariphy Communications, Inc, (Irvine, California) as a member of the company's technical advisory board, and XLoom Communications, Ltd (Tel Aviv, Israel) as Vice President US operations on developing high-speed optical components and electronics. During this time he also served as an expert witness in multiple intellectual property litigation cases.
Between 2008 and 2013 he managed the development of RF and millimeter-wave amplifier modules based on GaN-on-diamond technology as Vice President RF Electronics and co-founder of Group4 Labs, Inc. (Fremont, California), where in 2009 his team demonstrated the world’s first GaN-on-Diamond X-band power amplifier module. After Group4 Labs he co-founded and served as Vice President RF Electronics in Eridan Communications, Inc. (Santa Clara, California), a start-up company developing software-defined RF transmiters for wireless communications based on direct polar amplifier architecture. In 2012 he joined the faculty of University of Zagreb, Croatia.
Dr. Babić’s research interests include high-speed communications-component technology (semiconductor lasers and detectors, microwave amplifiers and other semiconductor devices) and optics. He has over 120 publications presented at conferences and in peer-reviewed journals, thirty granted patents, and one book chapter. His Web of Science h-index is 23 and Google Scholar h-index is 30.
