Abstract

We propose and demonstrate a passive compensation based stable radio-frequency dissemination system based on a mode-locked laser (MLL). The MLL is used as a timing signal source, which can provide multiple frequency references so that avoiding the use of multiple frequency multipliers. In the experiment, an 8.032-GHz signal is obtained with phase being compensated at a 3-km away remote site. Its single-sideband phase noise is reduced by 8.7 dB@10 Hz and 19.8 dB@10 kHz respectively compared to the uncompensated signal. The phase fluctuation of the compensated signal is kept around 2.7-degree level within 600s.
