Analog optical links are finding increased usage in a variety of commercial and military systems. Applications including analog storage, beamforming, and antenna remoting require links which demonstrate electrical performance rivaling state-of-the-art microwave devices. This talk will cover the fundamental principles of analog link operation and will detail recent work in low-noise, highly-linear analog optical links at the Naval Research Laboratory. New optical comb-based techniques for characterizing photodiode nonlinearities and addressing the challenges in extending link lengths to > 100km will also be discussed.
Jason D. McKinney received his PhD in electrical engineering from PurdueUniversity, West Lafayette, IN, in 2003.After completing his PhD, Dr. McKinney was a Visiting Assistant Professor (2003-2005) and Research Scientist (2005-2006) in the School of Electrical and Computer Engineering at PurdueUniversity where his first-of-its-kind research focused on photonically-enabled dispersion measurements of ultra-wideband wireless links and compression and shaping of ultra-broadband waveforms. Since 2006 he has been with the Applied Microwave Photonics Section, Optical Sciences Division of the U.S. Naval Research Laboratory. His research interests include low-noise, high-power analog optical links, ultrafast optical pulse processing and applications of photonics in ultrabroadband microwave systems. Dr. McKinney's research accomplishments at NRL include the first analog optical link demonstrating a noise figure below 10 dB over a multiple-GHz bandwidth, new linearized link architectures, and broadband optical comb-based techniques for photodiode characterization and analog signal transmission.Dr. McKinney has authored or co-authored more than 20 journal articles and over 30 conference presentations. He is the co-author of one book chapter and has two patent applications. Dr. McKinneyhas received a variety of awards for his research including the Chorafas Prize for doctoral research (2003) and as a finalist for the Optical Society of America / New Focus Student Award (2002).Dr. McKinney is active in both the Optical Society of America (OSA) and the Institute of Electrical and Electronics Engineers (IEEE).He is currently Chair of the Sub-Committee on Ultrafast Optics and Electronics for the IEEE Photonics Society.
