Abstract

We report the generation of ultra-low phase noise microwave signals using electro-optical frequency division. Two, independent 30 GHz eOFD oscillators are constructed and the measured phase noise for each oscillator is -151 dBc/Hz at 10 kHz offset and -109 dBc/Hz at 100 Hz offset. Phase locking to an external reference for long term synchronization is also demonstrated.
