Management Team


Dr. Charles H. Cox
President & CEO

Dr. Cox, president of Photonic Systems, Inc., is one of the inventors of the field that is now generally referred to as analog photonics, and has been active in the field for more than 25 years. He has participated in 8 government-industry studies in the area of photonics, served on the committees of 16 conferences in a variety of roles including general chairman and technical program chair. He holds 6 US patents, has given 45 invited talks on photonics and published over 70 technical papers. His textbook, Analog Optical Links: Theory and Practice, was published by Cambridge University Press in 2004. He has also co-edited another book and written two book chapters. For his contributions to the analysis, design and implementation of analog optical links, he was elected a Fellow of the Institute of Electrical and Electronic Engineers in 2001. Dr. Cox is an active member of the Advisory Group on Electron Devices (AGED) in the Office of the Secretary of Defense. Before founding PSI, Dr. Cox was employed at MIT and MIT Lincoln Labs. Dr. Cox received his SBEE and SMEE in Electrical Engineering from the University of Pennsylvania and his ScD in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology.

Dr. Edward Ackerman
 Vice President - Research & Development
Dr. Ackerman is PSI’s vice president of research & development. Before joining PSI, Dr. Ackermann’s experience includes more than 10 years as a photonics engineer at GE Electronics Laboratory and MIT Lincoln Laboratory. Among his notable accomplishments are: the first narrow-bandwidth amplifierless direct modulation analog optical link with RF gain (+3.7 dB at 900 MHz); the lowest noise figure ever demonstrated for an amplifierless optical link (2.5 dB at 130 MHz), and; a patented linearization technique that enables improved dynamic range across broad bandwidths and at higher frequencies than other linearization techniques allow.  Dr. Ackerman has co-edited a book and has authored or co-authored three book chapters as well as more than fifty technical papers on the subject of analog photonic subsystem performance modeling and optimization.

Doug Dillon
 Vice President - Business Opertions

Doug Dillon leads PSI’s sales, marketing, operations, finance and administrative activities.  Mr. Dillon brings over 30 years of sales, marketing, business development and engineering experience with leading fiber optic, radio frequency, electronic component and system manufacturers serving the telecommunications, defense and aerospace markets. Prior to joining PSI, Mr. Dillon led the sales and marketing teams at kSARIA and EM4 Photonics and was the VP Business Development at Clare Corporation.  He has also held senior sales and product marketing management positions at Lasertron and Radiall. After receiving a BS in electrical engineering from Tufts University, Mr. Dillon started his career as a design and development engineer at defense contractors Raytheon and Signatron.
