Abstract
Optical microwaves have the potential for ultra-low phase noise and high frequency signal generation, which becomes increasingly important for a variety of applications, e.g. in radar [1] and communications [2]. We report on the generation of ultra-low noise and long-term stable 9.6 GHz microwaves through optical frequency division of an offset-free comb, utilizing a novel scheme for GPS referencing. Instead of detecting and locking the carrier envelope offset frequency (fceo), the comb (DFC CORE 200 +) is based on difference frequency generation (DFG) [3], which cancels the fceo for each optical pulse. Thus, all actuators (temperature, piezo, oscillator) can be used for the stabilization of the comb repetition rate (frep) without the risk of crosstalk between frep and fceo. The error signal for frep stabilization is generated by a beat note of one comb mode with a low-phase noise continuous wave (cw) reference laser.
