Franklyn Quinlan (Fed)

Franklyn Quinlan is a Physicist and Leader of the Precision Photonic Synthesis Group in the Time and Frequency Division at NIST in Boulder, CO. He joined NIST in 2009 as a postdoctoral researcher, partly as a National Research Council postdoctoral associate. While at NIST, his research has focused on the development of optical frequency combs and ultrastable optical frequency references, new models and measurements of noise in the photodetection of ultrashort optical pulses, optical pulse shaping, low noise microwave signal generation, and photonic interconnects to cryogenic platforms. Over the years he has served on various technical committees for IEEE and OPTICA conferences, including co-chairing the IEEE Summer Topicals meeting on Portable Ultrastable Frequency Sources and Applications in July 2022.
