Ultra low phase noise frequency comb based microwave generation and characterization
We report on the generation of ultra low phase noise microwave signals at 12GHz by photodetecting the pulse train of an Erbium doped fiber based optical frequency comb phase locked to a ultra narrow linewidth ultra stable laser at With advanced photodetection techniques and homemade phase noise measurement apparatus, our experiment demonstrates generation of a microwave source with absolute phase noise below 170dBc/Hz at 10kHz and above, and below 100dBc/Hz at 1Hz from a 12GHz carrier, which pushes even further the best results reported so far.
