Hybrid Solution for Joint Transfer Time Signal With Both RF Frequency and Optical Frequency
IEEE Photonics Journal, 2021 We demonstrate a hybrid solution for simultaneous transfer of ultra-stable optical frequency, RF frequency and time signal on a 100 km fiber spool with the same wavelength based on coherent demodulation and optical phase-lock-loop (OPLL).

Noise characteristics of a polarization-duplex dual-comb fiber laser based on a single gain fiber
Results in Optics, 2023 We demonstrate gain-sharing polarization-duplex dual-comb laser. Here, a nonlinear amplifying loop mirror (NALM) with a single gain fiber is used to achieve simultaneous mode-locking for the generation of the two frequency combs with slightly different ...
