Leif A. Johansson received the Ph.D. degree in engineering from University College London, London, U.K., in 2002.
He is currently a Research Scientist with the University of California, Santa Barbara. Leif’s research interests include design and characterization of integrated photonic devices for analog and digital applications, and analog photonic systems and subsystems. In 2005, he co-founded Freedom Photonics to commercialize indium phosphide integrated photonic circuit technology.

Milan Mashanovitch (Mašanović)
Dr. Milan Mashanovitch (Mašanović) is a project scientist/adjunct professor at the Electrical and Computer Engineering Department of the University of California in Santa Barbara.
Milan received his Dipl. Ing. degree from the School of Electrical Engineering, University of Belgrade, Belgrade, Serbia, as a valedictorian, in 1998. He started his graduate work in the field of integrated photonics at the University of California Santa Barbara in 1998, where he obtained his M.S. (2000) and Ph.D. (2004) degrees. Since 2004, he has been working as a staff scientist/adjunct professor at UC Santa Barbara.
Dr. Mashanovitch is the author or coauthor of more than 85 research papers in peer reviewed journals and conferences. He co-authored the second edition of the book, “Diode Lasers and Photonic Integrated Circuits” with Larry Coldren and Scott Corzine, published by John Wiley in 2012. His current research interests include InP photonic integrated circuits (lasers, transmitters, wavelength converters, optical routers), technologies for packet packet-switched optical networks, as well as optical switching technologies for local area networks and harsh environments.
Dr. Mashanovitch has successfully contributed to a number of DARPA funded photonic integration programs: Next Generation Internet (NGI); Chip-Scale WDM (CS-WDM); and Data in the Optical Domain Networks (DOD-N) as a member and photonic integration effort lead on the LASOR (Label Switched Optical Router) team.
Dr. Mashanovitch is a recipient of numerous awards, scholarships and travel grants, including the 2004 IEEE Lasers & Electro-Optics Society Graduate Student Fellowship Award, the 2003 Best Student Paper Award at the Indium Phosphide and Related Materials Conference, and the Studenica Foundation Graduate Student Fellowship Award.
In 2005, Dr. Mashanovitch co-founded Freedom Photonics LLC, a successful photonic integration company based in Santa Barbara, California, which commercializes advanced photonic components and subsytems for defense and commercial markets.
