	"description": "\u003Cp\u003E\u003Cstrong\u003ETitle:\u003C/strong\u003E\u0026nbsp\u003BFrequency\u002DComb\u002DBased Optical Timing Networks\u003C/p\u003E\u000A\u003Cp\u003E\u003Cstrong\u003EAbstract:\u003C/strong\u003E The optical frequency comb has enabled a wide range of frequency, time, and distance metrology applications due to its precise, rigid, and referenced optical output. However, the very rigidity that makes the frequency comb an excellent time\u002Dfrequency ruler limits its applicability to comb\u002Dbased sensing, with many operating far from quantum\u002Dlimited sensitivity. For instance, frequency\u002Dcomb\u002Dbased two\u002Dway time transfer relies on the detection of an incoming optical comb pulse train from a distant location. These incoming comb pulse trains may be weak, and amplification is costly \u0026mdash\u003B operation close to the quantum limit would dramatically increase the scope of what is possible in terms of range, SWaP (size, weight and power) and link loss. In turn, that increased scope would enable comparison of state\u002Dof\u002Dthe\u002Dart optical clocks for the future redefinition of the second, a wide range of fundamental physics tests, and chronometric geodesy.\u003C/p\u003E\u000A\u003Cp\u003EHere, I\u0027ll present our development of a quantum\u002Dlimited approach to optical time transfer that relies on a time\u002Dprogrammable frequency comb to overcome the inherent trade\u002Doffs that arise from the rigid operation of a traditional comb. These programmable combs have pulse time and phase that can be digitally controlled with \u0026plusmn\u003B2\u002Dattosecond accuracy, enabling their use as an optical tracking oscillator. Using frequency combs as optical tracking oscillators to reach the quantum limit for optical time transfer, we have demonstrated sub\u002Dfemtosecond time transfer across a 300\u002Dkm terrestrial free\u002Dspace link with more than 100 dB of loss, a factor of 10,000 lower received\u002Dpower threshold than previous frequency\u002Dcomb\u002Dbased approaches. I\u0027ll show results from this 300\u002Dkm demonstration as well as more recent work connecting optical atomic clocks across open\u002Dair paths.\u003C/p\u003E\u000A\u003Cp\u003E\u003Cstrong\u003EAbout the Speaker: \u003C/strong\u003ELaura Sinclair is the optical time transfer project lead in the Fiber Sources and Applications Group, which is part of the Communications Technology Laboratory at the National Institute of Standards and Technology (NIST) in Boulder, Colorado. She received a bachelor\u0027s degree in physics from the California Institute of Technology in 2004, a doctorate in physics from the University of Colorado Boulder in 2011, and was a post\u002Ddoc at NIST Boulder, including a National Research Council post\u002Ddoctoral fellowship, before joining the staff. She\u0027s was awarded a Presidential Early Career Award for Scientists and Engineers (2019), a Department of Commerce Gold Medal for Scientific/Engineering Achievement as part of the Boulder Atomic Clock Optical Network Collaboration (2019), a NIST Excellence in Technology Transfer Award (2024), the Arthur S. Flemming Award for Basic Science (2024) and an Optica Fellow Award (2026). Her research focuses on the development of optical frequency combs and their wide\u002Dranging applications, particularly to optical time transfer and ranging. With the optical time transfer project team, she has recently demonstrated optical time transfer at the quantum limit, achieving sub\u002Dfemtosecond time synchronization over 300 kilometers of air.\u003C/p\u003E",
