Abstract

50 GHz repetition rate optical frequency comb with very low phase noise is experimentally demonstrated by incorporating an optical frequency comb generator (OFCG) in an optoelectronic oscillator (OEO). To the best of our knowledge, this is the highest repetition rate optical frequency comb ever achieved by an OFCG. What more important is that, the OFCG is driven by the 50 GHz millimeter-wave signal oscillating in the OEO, and no frequency synthesizer is needed. The singlesideband (SSB) phase noise of the 50 GHz signal oscillating in the OEO is theoretically analyzed by the Leeson formula. The calculation result shows that the SSB phase noise could be as low as -125 dBc/Hz at 10 kHz offset with our experimental parameters.
