A photonic oscillator, locked to a master RF synthesiser, was built by using a monolithic dual‐wavelength DFB semiconductor laser submitted to a frequency‐shifted optical feedback. A [3; 10] GHz tuning range is reported, with a phase noise level lower than −70 dBrad 2 /Hz at a 10 Hz offset from the carrier.
