Branching optical frequency transfer with enhanced post automatic phase noise cancellation
Ruimin Xue, Liang Hu, Jianguo Shen +2
We present a technique for coherence transfer of laser light through a branching fiber link, where the optical phase noise induced by environmental perturbations via the fiber link…

Fundamental Limitations of Rayleigh Backscattering Noise on Fiber-Based Multiple-Access Optical Frequency Transfer
Liang Hu, Xueyang Tian, Guiling Wu +2
While it has been shown that backscattering induced phase noise can be suppressed by adopting acoustic-optic-modulators (AOMs) at the local and remote sites to break the frequency…

Multi-node optical frequency dissemination with post automatic phase correction
Liang Hu, Xueyang Tian, Guiling Wu +3
We report a technique for coherence transfer of laser light through a fiber link, where the optical phase noise induced by environmental perturbation via the fiber link is compensa…
