Abstract :
We report on the generation of a low phase noise millimeter-wave signal at 100 GHz with a dual-frequency laser and a high-speed photodiode. The laser beatnote is phase-locked on the 10th harmonics of a 10 GHz synthesizer through an original photonic down-conversion scheme. The spectral purity of the millimeter wave signal has been fully characterized: it is spurious free over a large bandwidth and its phase noise is limited by the synthesizer itself (-90 dBc/Hz at 10 kHz).
