Coupled optoelectronic oscillators are establishing themselves as stand-alone low-noise frequency sources and short optical pulse generators at multi-gigahertz rates, with applications including arbitrary RF waveform generation and RADAR.  Transforming the COEO into a self-contained optical frequency comb source with multi-gigahertz line-to-line spacing would open it up to a host of new applications in coherent communication and signal processing, such as arbitrary optical waveform generation and optical code division multiple access (OCDMA) systems.  This talk will cover our work in developing an intracavity etalon-based COEO with 10 GHz comb spacing.  In this oscillator, both the optical carrier frequency and the comb spacing are actively stabilized to the etalon, producing ~200 10 GHz-spaced stabilized comb lines and low jitter sub-picosecond pulses.  Investigations into the comb dynamics via measurements of fixed-point frequencies of this oscillator will also be discussed.

 

Franklyn Quinlan received M.S. and Ph.D. degrees from CREOL, the College of Optics and Photonics, University of Central Florida, Orlando, in 2005 and 2008 respectively.  His research interests include low noise mode-locked lasers and their applications in coherent communication and microwave photonics.  Dr. Quinlan has published approximately 15 journal articles as well as numerous conference proceedings papers.  He was selected as a finalist for the 2008 Optical Society of America (OSA)-New Focus/ Bookham Student Award and won first place in the Student Paper Competition at the 2007 Joint Conference of the European Frequency and Time Forum and the IEEE International Frequency Control Symposium.  Dr. Quinlan has served as OSA Student Chapter President and is a member of the IEEE Lasers and Electro-Optics Society (LEOS) and the IEEE Ultrasonics, Ferroelectrics, and Frequency Control Society (UFFC).
