Item Open Access Long range fiber noise cancellation(Colorado State University. Libraries, 2024) Helburn, Noah, author; Sanner, Christian, advisor; Brewer, Sam, committee member; Wilson, Jesse, committee memberOptical atomic clocks are beyond timekeeping applications an increasingly important tool for testing fundamental physics and pushing the quantum science frontier. Being able to compare remote optical clocks by sharing coherent laser light between them opens exciting scientific perspectives. Optical fibers are almost ideal guides for sending light over long distances, but they induce phase noise on the light travelling through them. We demonstrate an actively phase-stabilized optical fiber link over a distance of 80km. A fractional frequency instability of 7 × 10−15 at 1 s and 6.3 × 10−18 after 1800 s was achieved.
