Frequency-Independent Phase Noise in a Dual-Wavelength Brillouin Fiber Laser

An in-depth analysis of the phase noise of a microwave oscillator based on dual-wavelength stimulated Brillouin scattering is presented. The system is investigated under the influence of injection-locking and also in a regenerative-frequency configuration. Measurements from 1 to 25 GHz demonstrate t...

Summary:An in-depth analysis of the phase noise of a microwave oscillator based on dual-wavelength stimulated Brillouin scattering is presented. The system is investigated under the influence of injection-locking and also in a regenerative-frequency configuration. Measurements from 1 to 25 GHz demonstrate the invariance of the phase-noise spectrum with respect to carrier frequency. Phase noise of -90 dBc/Hz at 1-kHz offset is shown, and is compared to the best reported performance of optical heterodyne sources. The frequency stability of the oscillator is also discussed.
