Abstract
We present a novel frequency comb-based system for optical two-way time-frequency transfer to support very long distance free-space links between clocks. Our Photon-Efficient Agile Comb Optical Clock Synchronization (PEACOCS) system supports sub-femtosecond oscillator synchronization with up to 90 dB of link loss equating to few picowatt levels of received power. Such low power operation is a promising step towards terrestrial links in the 100s of kilometers as well as ground-to-satellite links.Proceedings Title
