Dr. Charles H. Cox, President and CEO

Dr. Cox, president of Photonic Systems, Inc., is one of the founders of the field that is now generally referred to as analog photonics, and has been active in the field for more than 15 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 a 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.

Dr. Edward I. Ackerman, Vice President of Research and Development

Dr. Ackerman is PSI’s vice president of research & development. Before joining PSI, he worked for five years each 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. He 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.
