We report on an optoelectronic oscillator (OEO) at 10 GHz based on a single 1 km long fiber delay, and exhibiting simultaneously an ultra-low close-in phase noise (-94 dBc/Hz @100 Hz) and a low spurious level (below -110 dBc/Hz). These results are well predicted by a model taking into account the frequency and intensity noise from the laser source that are converted into phase noise.
