Abstract:
An architecture for an optoelectronic oscillator uses Stimulated Brillouin Scattering (SBS) to seed, filter and amplify the oscillation signal in an overlapped oscillator loop for both a RF modulated optical sideband and a SBS signal. By phase matching the RF modulated optical sideband generated by SBS with the SBS signal, the feedback will collapse the bandwidth of the SBS signal and in turn the bandwidth of the Brillouin frequency signal, which also serves as a filter to filter out multiple undesired OEO loop modes. The embodiments herein result in reduced phase noise and increased stability.

Claim (Index 15):
The system of  claim 14 , further comprising an electrical signal filter in the electrical signal path between the photodetector and the electrical input of the optical modulator in order to filter out frequencies other than the beat frequency between the laser carrier signal and the SBS signal so that the frequency of the modulating signal supplied to the electrical input of the optical modulator matches the beat frequency between the laser carrier signal and the SBS signal.
