FIG. 1.

Setup schematic. FOFC: fiber-based optical frequency comb; USCW: ultrastable continuous wave laser; and VCPS: voltage controlled phase shifter.

FIG. 2.

Phase noise power spectral density of the difference of the two 11.55 GHz microwave signals extracted from FOFCs. Assuming identical uncorrelated behavior of the two systems, the phase noise for a single FOFC is 3 dB lower. Curve 1: no noise reduction technique was applied; Curve 2: with VCPS phase correction and stabilization of the optical power incident on the microwave generating photodiode (both AOM and pump power feed back give the same result); Curve 3: readout system floor.

FIG. 3.

FFS measured by Allan standard deviation (left scale) and time deviation (TDEV, right scale) for a single optics-to-microwave FOFC system. Top continuous line: FFS with power stabilization on AOM; diamonds and circles, respectively, FFS and TDEV with power stabilization on pump current control; bottom continuous line: FFS floor of the measurement system.
