Optical Time and Frequency Transfer

Our group is pursuing frequency comb based optical two-way time-frequency transfer to support state-of-the-art optical clock measurements. Optical clock networks will enable fundamental physics tests, increased sensitivity for coherent sensing, improved timing and navigation and the distribution of an optically-defined time standard. However, these networks will require the parallel development of optical links. We have leveraged the advent of robust optical frequency combs along with advanced digital signal processing techniques...
