Scott Diddams

Last updated

Scott Diddams holds the Robert H. Davis Chair [1] at the University of Colorado Boulder, where he is also Professor of Electrical Engineering and Physics.[] [2] He carries out experimental research in the fields of optical frequency combs, precision spectroscopy, nonlinear optics, microwave photonics and ultrafast lasers. He was previously a group leader and Fellow of the National Institute of Standards and Technology (NIST) based in Boulder, Colorado.

While a postdoc in the lab of Nobel laureate John L. Hall, Diddams demonstrated the self-referenced optical frequency comb [3] and subsequently used it to realize the first optical clocks [4] . Throughout his career, he has continued to pioneer the development of frequency combs in multiple platforms and use them in numerous applications--including astronomy, low-noise microwave synthesis, and spectroscopic sensing. He has also been active in the miniaturization of optical frequency combs and atomic clocks. [5] [6]

He is a Fellow of Optica, American Physical Society, and IEEE. Among other awards, he is recipient of the 2017 IEEE UFFC Rabi Award [7] , the Presidential Rank Award in 2021 [8] , and the 2023 C.E.K. Mees Medal. [9] In 2025, Diddams was elected to the National Academy of Engineering. [10]
