All-passive multiple-place optical phase noise cancellation

We report on the realization of delivering coherent optical frequency to multiple places based passive phase noise cancellation over a bus topology fiber network. This technique mitigates any active servo controller main link and at arbitrary access as opposed conventional technique, in which an compensation circuit has be adopted stabilize link. Although residual power spectral density proposed turns out factor seven higher than that multiple-access when place is close end link, it could largely suppress introduced by bumps, improve response speed recovery time, minimize hardware overhead systems with many stations connections without need for circuits including discriminators compensators. The considerably simplify future efforts make precise signals available users, required some large-scale science experiments.
