Dr. Jonathon S. Barton

Dr. Jonathon S. Barton has over nine years of experience working with integrated photonics including, modeling, design, fabrication, testing and packaging of photonic integrated circuits. Prior to co-founding Freedom Photonics LLC in January 2005, he was employed by Agility Communications Inc.; a start-up company recently acquired by JDSU Inc. which pioneered monolithically integrated widely-tunable SGDBR based lasers and transmitters. At Agility, Dr. Barton was responsible for successful implementation of device modeling and design, fabrication and antireflection coating process development, and testing. Additionally in 1998, Dr. Barton worked at Sandia National Laboratories on the reliability testing of radiation-hardened VCSELs.

Dr. Barton earned his B.S. in Electrical Engineering and Material Science Engineering, at the University of California, Davis. He was an Intel fellow in 2004 and completed his Ph.D. in Electronic Materials at UC Santa Barbara. At UC Santa Barbara, he pioneered, designed and developed the world’s first C-band tunable monolithically integrated Mach-Zehnder transmitter in Indium Phosphide, operating at 40 Gbps. Currently Dr. Barton leads the research and development efforts of Freedom Photonics. He is actively involved in photonic chip design, pilot production and prototype development. Furthermore, Dr. Barton has coauthored over seventy papers, invited and contributed talks on tunable lasers and photonic integrated circuits, at various international conferences.

Dr. Leif Johansson

Leif Johansson is Chief Scientist at Freedom Photonics. Following his PhD at University College London, UK, he joined UCSB in 2002 as a Research Scientist working on InP photonic for digital and analog applications and in RF photonic systems, and has authored or co-authored over 100 publications in these areas. He has played a leading role to define and lead several high-profile projects and has been PI or Co-PI on a range of RF photonic related programs, most notably the recent UCSB/PHOR-FRONT effort, where he oversaw systems integration and system analysis efforts. In 2005 he co-founded Freedom Photonics together with Dr Jonathon Barton and Dr. Milan Mashanovitch to commercialize high-performance, advanced InP photonic integration technologies.

Dr. Milan L. Mashanovitch

Dr. Mashanovitch brings to the team a diverse engineering background, including more than 8 years of experience in working with integrated photonics, spanning over modeling, design, fabrication, testing and packaging of photonic integrated circuits. Dr. Mashanovitch is actively involved with seeking new business opportunities in diverse markets within Freedom’s scope of competence. Additionally, he is in charge of overall chip manufacturing operations, and involved with prototype testing and qualification.

Prior to co-founding Freedom Photonics LLC, Dr. Mashanovitch designed the world’s first integrated C-band tunable wavelength converter operating at 10 Gbps, and more recently at 40 Gbps. There, Dr. Mashanovitch acquired direct experience in planning, budgeting, and oversight of execution of new and ongoing research projects, as well as management and planning of the research projects’ resources for timely execution of research tasks and goals. In addition, Dr. Mashanovitch was in charge of the photonic device outsourced manufacturing and coordination of related efforts with other industrial and government research team members and partners.

Prior to joining UCSB, Dr. Mashanovitch worked as an engineer at Lucent Technologies in the Netherlands with the wireless IP hardware networking group, as well as the Jet Propulsion Laboratory in Pasadena, CA, in the Planetary Science Division.

Dr. Mashanovitch has coauthored over seventy papers on photonic integrated circuit technologies and packet switching, and has given numerous invited and contributed talks at various international conferences. Dr. Mashanovitch earned his Dipl. Ing. in Electrical Engineering, University of Belgrade, Serbia, 1998, and holds a M.S and P.hD in Electrical Engineering, from the University of California, Santa Barbara. During his graduate studies, he earned several awards, including the prestigious Graduate Student Fellow, IEEE-Lasers and Electro-optics Society in 2004 and the Best Student Paper Award – XIV Indium Phosphide and Related Materials Conference in 2003.
