We demonstrate a single-sideband opto-RF oscillator, based on a monolithic InGaAsP chip containing two DFB lasers. The heterodyne signal is stabilized by a hybrid method, combining optical and electronic feedback. It leads to a locking of the beating frequency onto a filtered version of itself. Our table-top setup provides a phase noise level down to-75 dBc/Hz at 1kHz offset from a 10 GHz carrier. Potential phase noise improvement and integration scheme in a single component are discussed.
