We report the experimental realization of a photonic oscillator based on dedicated monolithic dual-wavelength DFB lasers. The oscillator is locked to a master RF synthesizer using an all-optical feedback loop. A [3-10] GHz tuning range is reported, with a phase noise level lower than -55 dBrad2/Hz at 10 Hz from the carrier, instrument-limited.
