Low jitter optical and microwave synthesis with frequency combs

An optically-stabilized femtosecond laser optical frequency comb can serve as a source of optical and microwave waveforms with absolute integrated timing jitter on the scale of a few femtoseconds. This ultralow jitter is due to the stability of a passive optical cavity, which is the frequency reference for the system. We will present recent results in the generation of low phase noise 10 GHz signals and will discuss our progress towards the synthesis of more complicated waveforms.
