The oscillator has an optoelectronic closed loop (10') including an optoelectronic modulator of an optical bi-frequency laser (1'), an optical fiber (12'), a photomixing photodiode (13'), and a filtering unit for filtering a frequency of oscillation. The laser includes two sections (1'a, 1'b) to emit two optical signals of two frequencies (V1, V2), respectively. The photodiode detects the optical signals and outputs an electrical signal. The modulator is connected to one of the sections, where the laser, photodiode, and the modulator produce the filtering unit.
