Abstract :
We demonstrate a 10 GHz photonic oscillator based on optical frequency division of a high-stability optical reference with a modelocked fs laser. Characterization with a second independent photonic oscillator reveals a close-to-carrier phase noise that is <; 100 dBc/Hz, reducing to a shot noise floor of -156 dBc/Hz at a 1MHz offset.
