| Title: |

| Abstract: |
We demonstrate a 10 GHz hybrid oscillator comprised of a phase stabilized optical frequency comb divider and a room temperature dielectric sapphire oscillator. Characterization of the 10 GHz microwave signal via comparison of two independent hybrid oscillators yields a combined phase noise, L(f) = -100 dBc/Hz at a 1 Hz offset and L(f) < -185 dBc/Hz for frequencies > 1 MHz. The associated absolute timing jitter is 0.6 fs (1 Hz to 5 GHz). |
