Stable radio-frequency transfer over optical fiber by phase-conjugate frequency mixing

He, Yabai; Orr, Brian J; Baldwin, Kenneth; Wouters, Michael J; Luiten, Andre N; Aben, Guido; Warrington, Richard B


We demonstrate long-distance (≥100-km) synchronization of the phase of a radio-frequency reference over an optical-fiber network without needing to actively stabilize the optical path length. Frequency mixing is used to achieve passive phase-conjugate cancellation of fiber-length fluctuations, ensuring that the phase difference between the reference and synchronized oscillators is independent of the link length. The fractional radio-frequency-transfer stability through a 100-km "real-world"...[Show more]
